One device for one function – I admire Anson’s unique and stable approach of developing masterpieces in every audio hardware niche… Let’s be honest, even a perfect device with limited functionality is risking to be buried down by millions of all-in-one mere consumer choices just because it is more convenient to use… DSLRs are almost out of the consumer market, as well as voice and video recorders, book readers, DAPs, etc. Most of the users would still agree that prosumer or pro-level stand-alone devices deliver much better quality but who cares if the content is made for and consumed in social networks? Personally, I regret the times when everyone tried to acquire the best shot out of 24-36 frames instead of storing thousands of useless files… That is why all Dethonray products impress me this much – they build a reference to those good old times when everything was designed for “pro”, forcing users think and progress.

Pegasus SG1 is not an exception. It is a sixth masterpiece developed by Anson and released in June 2022 that fills Bluetooth audio niche in Dethonray lineup. DTR1 DAP was the first, followed by Honey AMP. Later came one of the best bundle in portable HiRes audio world consisting of DTR1+ and Tender 1 planar IEMs and now comes the Pegasus. Here is the corresponding retrospective picture from the official Dethonray website:

All of those devices are highly rated by the reviewers and respected by both – audio “fans” and “philes”. Personally, I am using DTR1, DTR1+ and Tender 1 for a long time and can state that both DAPs and Tender IEMs still remain the ultimate audio performers with no problems in technical aspects either. Moreover, those devices had already gained some magic aura around and turned to collectibles. I still wouldn’t call Dethonray a “boutique” brand since boutique means something extravagant and limited in amount but not necessarily having high quality of the production. Opposingly, Dethonray is managing to deliver high quality of functioning along with similarly high quality of the production even despite smaller volumes compared to market mastodons. Therefore, I would rather name Dethonray as high-end brand working in the respective niche.

So, the Pegasus SG1 – what is it designed for? Here are the specs first:

As can be seen from the specs – Pegasus main and the only purpose is acting as Bluetooth receiver -> processing the incoming stream -> converting to audio signal. It incorporates various popular audio codecs, including the HiRes LDAC (24bit/96kHz). Outputs presented by both – 3.5mm SE and 4.4mm BL ports. The main feature shared across all Dethonray devices is also present in Pegasus technical design – DPPU (Desktop Plus Power Unit)：

DPPU adapts dual high-density battery customized power system, designed for High-Fidelity while ensuring separation of digital and analog power to eliminate digital circuit noise from the source, alike an enhanced DAP + Amplifier system but with a minimal path and hard soldered joints with no compromises.

There is one additional feature that is very important but rarely stated about Pegasus: the ability to change sound signature by different FW versions. It comes with “Rhapsody” FW by default and can be changed to “Serenade” FW on behalf of a user. I’ve seen such implementation once before in Tempotec / Hidizs USB DACs that really did a job of changing the sound to user preference. This is much more convenient than replacing Op-Amps or any part of the hardware but still requires some understanding and PC skills.

Back to Pegasus SG1 description:

It comes in black box regular for all Dethonray devices. Box is stiff and perfectly does a job of securing its components. Single layer inside consisting of foamy insert with the cutout that holds Pegasus at place. Than goes the beauty – Pegasus SG1 resting there with its perfectly polished glass top cover facing outwards and tiny aluminum bezel around.

I’ve seen 4 body colors available: purple, red, black and mint and I can say that red and purple look punchy.

Dethonray logo underneath front glass panel has multicolor LED backlight that resembles the device current state.

Another beautiful element is the volume knob that combines clever design for comfortable grip with peculiar shape, appropriate color and matt finish.

Both output ports are located on the top edge. All control buttons gathered on the left edge.

Bottom edge holds type-C charging port and the additional LED indicator that duplicates front facing logo in its behavior.

Very neat, strict and beautiful design at the same time. Feels rigid and comfortable in hands. The only drawback is that placing it in a pocket with keys, phones or other stuff might leave the marks on its perfect surfaces. Jello-stickers would definitely help here.

Pegasus SG1 in operation:

Since the Pegasus is a BT receiver, first thing to do after initial charging is to connect it over Bluetooth to any audio source. Of course, the best performance can only be achieved with the sources capable of LDAC or apt-X HD codecs. Most of the recent phones, tablets and DAPs would surely support at least one. Although, Apple users would still be limited to lossy AAC codec instead due to Apple closed politics on that (devices for the professionals, I bet).

There is no multipoint feature in Pegasus, therefore – only 1 device at once. But the previously connected would be stored in BT controller memory for fast reconnection in the future.

The process of pairing is very fast, LED comes of a help to show whether Pegasus is still pairing (blinks) or has already paired (constantly lit). You would only have to choose PEGASUS SG1 under phone BT available devices and tap on connect. Most of the sources would state codec that is being used for audio transfer between the devices. In my case it is the most capable LDAC (Xiaomi Redmi Note 8Pro). Unfortunately, battery status is not being transferred from Pegasus to phone. Dethonray claims around 8 hours of continuous performance with SE and 6 hours with BL output. Real world tests proved those figures right.

Upon the connection, there are 3 buttons on Pegasus that work as expected: PLAY|PAUSE, NEXT and PREVIOUS. Buttons feel tight, no rattling. The additional two-way switch is designed to change from low to high gain depending of the headphones impedance. It is really better to stay off selecting high gain for IEMs lower than 16Ohms or it might be damaged. Volume knob has pleasing feel of tight travel and comfortable grip. It acts pretty accurately, delivering smooth volume change in both directions. Much more convenient than discrete volume buttons found in phones, USB DACs and in some DAPs that change it quite abruptly. Here you can select any desired levels, starting with the barely heard ones.

Pegasus stays stays cold during operation with only slight warming up while the battery takes charge. Type-C port is only used for charging | FW upgrades but the function of USB DAC is not available.

FW change:

As said before, this BT DAC has two different firmware versions. Rhapsody (default) is more assertive and Serenade is more calm and melodic in its signature. Changes in sound are audible but not vital. It is more about rounding some edges and slightly changing the entire timbre. Personally, I prefer Serenade version over Rhapsody for its slightly added warmth and smoothness. Phapsody is better for more aggressive and rhythmic genres.

Here is the link to FW download on Dethonray website: LINK

The process of switching to another FW is quite cumbersome but doable. Here are the steps:

The sound:

Pegasus SG1 is impressive. Sounds linear with the emphasis on mids which sound thick and pleasingly warm. Sound perception is natural and balanced. Quite hard to notice any discrepancies that would disclose its wireless connection.

Bass is well-resolved and emphasized. This bleeds into mid bass and affect the entire sound with such pleasing warm and thick strokes. Fortunately, mid bass section is still maintaining great dynamics and tightness to sound juicy. Mids stand out as the central part of the presentation and deliver voices and instruments naturally. No hisses or sibilants even with sensitive IEMs. Lows definitely have more impact on mids than treble. Slight lack of texturing due to BT connection but still feels very musical due to accurate and smooth delivery. Despite wireless connection, treble is well-extended, with no abrupt nuances. Good clarity and correct balance with other ranges without any emphasis makes treble very accurate and appealing, leaving the whole sound closer to the dark side.

Great choice of tuning for such BT DAC. Possibly the best to go away from dry and analytical approach to very musical one that also hides some imperfections.

Conclusion:

Pegasus SG1 is the best sounding Bluetooth DAC among all BT audio devices of al types I’ve tried so far. IEMs with BT lace, BT earhooks, TWS, BT ultra-portable DACs – all suffered from apparent wireless connection limitations especially noticeable on abrupt treble and limited extensions. It might be the outcome of device hardware size, design or multifunctional abilities when some are developed appropriately and some are just for show. Pegasus, on its turn, is made for one function and made perfectly: in terms of design, logics and performance. It uses the best BT codecs possible, shows no hiccups in operation and makes the sound truly appealing. Moreover, it sounds almost indistinctive to very good portable wired setup combinations. Feels like with the Pegasus SG1, going wireless is no longer a compromise either with headphones or in desktop use with active speakers or amps.

Sennheiser, as a brand, doesn’t need our presentation. It is among the largest and oldest manufacturers of personal and professional audio products, located in Germany and existing for more than 75 years. No doubt that their professionalism allows to create the most polished used experience mixed with the highest functionality at the forefront of the progress. A bit of conservatism that stops them from releasing raw products just to overtake the competition only show brand strength and differs it from smaller, less patient and picky ones. As the result, the end customer might play with the latest technology from the smaller brands, but the will to try similar products from the industry leaders still remains.

Couple of more words about the vendor which plays and important role in this review: we are rarely dealing with the largest and the most famous audio brands due to a simple reason – its price. Most of the hundreds of IEMs and other products that has been reviewed on our website are less expensive rivals which we can or cannot recommend to others according to our expertise. There are a lot of products which became a real bargain even in comparison to matured brands. Whereas some are just a shade of what it is meant to be… For brands of the first echelon like Sennheiser, Audio-Technica, Yamaha, Beyerdynamic, JBL, etc, 99% of their products is the win, with almost no mishaps. But the price bar is much higher, in similar 99% of the cases. The only option to have a bargain here is to find the best price from trusted vendor. In case of Sennheiser and Audio-Technica (more brands would show up there soon) there is Voonaudio store that lists 100% authentical products with the best price compared to other online stores (excluding when brands provide the additional seasonal super sales/deals on Amazon or other official online shops). This finally makes us possible to test some famous products that were quite pricy before (product price + logistics). Momentum TW 3 set was provided for the review for free but considering the offer, we can finally plan some spendings on less common items like turntables, for instance.

Back to Sennheiser Momentum True Wireless 3:

Technical specs:

Most interesting features to outline in this product:

• Supports aptX and aptX Adaptive (24bit/96kHz, up to 620Kbps) Bluetooth codecs
• Active Adaptive Noise Cancelling technology with Transparency mode
• 3 mics / channel
• Smart control application for iOS and Android
• Wireless and wired charging
• IPX4 waterproof
• Multipoint support (2 devices at once)
• Great fit by exchangeable ear tips and fins

Device packaging and bundle:

Momentum arrived bit later than expected due to reasonable problems in the logistics between China and Ukraine. We were still surprised that it took only 16 days by a regular air parcel method to arrive. European hub reported that it arrived from China in 8 days, the rest was truck transportation from Germany to local hub and to its final destination afterwards.

The appearance of the product was definitely created with the intention to greet the customer with Christmas and New Year celebrations. Creativity and care stands behind the additional outer wrappage which also contains Voonaudio CEO (Samantha Lind) signature.

Thanks guys, happy New Year too!

Here is the standard Momentum True Wireless 3 box without the additional cover:

Box contains large amount of product and company information but the most important is the availability of counterfeit protection sticker that shows that it is 100% original Sennheiser TWS.

The insides are split in two vertical compartments, one holds IEMs with charging case and another stores all provided accessories.

Apart from TWS and its case, the bundle consists of:

• 4 pairs of silicone ear tips (XS, S, M, L)
• 3 pairs of fins (with slightly different shape)
• type-C to USB A charging cable
• user manual, warranty card and couple of leaflets

Can’t tell that this is the best bundle we’ve seen among all TWS that we’ve tested, but the availability of different sizes of fins and tips builds the confidence that the fit should be great.

Design, feel and fit:

As the representative of TWS IEMs, Sennheiser Momentum True Wireless 3 consists of left and right channels and charging case that plays a role of a power bank. Case is made of plastic, fully wrapped with cotton material. Sennheiser logo at the top, type-C charging port with LED indicator at front.

Top case cover holds quite tight by the large integrated magnet. No way it would open by itself. Inner IEM contacts also hold each channel in the compartment with relatively strong magnetic force that would secure it from falling out if turned up side down. Case build quality is excellent, everything is perfectly aligned and crafted.

IEMs have similarly perfect finish and crafting – made of plastic but feels rigid. Perfectly aligned parts, clear openings and neat look. Top covers consist of brand logo, couple of mics and touch sensitive panels:

4 contacts, additional mic, proximity sensor and LED indicators on the bottom.

Sound channels are covered with nylon mesh for dust protection purpose. Additionally, each ear tip has its own dust protection in a form of foamy insert. Glad to have that since the most of the problems with IEMs happen due to dust and dirt getting inside the shells.

At first we were not confident about the fit – IEMs look pretty large and feels heavy. Although, its shape together with different fins and ear tips allowed to find the most comfortable and tight sitting option that even allows to use Momentum True Wireless 3 during active workouts. Weight is not causing any inconvenience either. When fit is great you just forget about IEMs in your ears. Of course, it would not win over any custom-shaped wired IEMs, but surprisingly good and gives the additional freedom due to being wireless.

One of the most important questions – how good is the fit comparing to other types of TWS, like earbuds (certain Apple products) or IEMs with long leg (like Huawei FreeBuds 4i), for instance…. Unfortunately, it is still a question of compromise:

• Earbuds are the most comfortable for long and calm use but least secure for fitness and worst in sound quality due to lack of passive noise isolation
• IEMs like Huawei FreeBuds 4i are less secure than Momentum TW 3 during active movements and have worse sound due to lack of room inside the case but should have better voice pick up due to lower position of microphones.
• Momentum feels much more secure but heavier. It might not be as comfortable than other two through the whole day.
• As to such types of TWS as ear hooks with IEMs (FiiO UTWS 3) – best sound quality due to optional preferred IEMs but the worst fit – feels bulky and not too natural.

Apart from physical comfort and fit, there is also such very important aspect of TWS IEMs as its acoustic feel. Some people might have bad experience with wearing in-ear monitors for a long time. It really might cause a lot of discomfort, physically as well as psychologically. Constant pressure against tympanic membrane may cause dizziness, headache, nausea, etc. But we can assure you that it is not about the Sennheiser Momentum 3 – it has the necessary transparency modes among all of its features to completely remove any negative effect during the long-time wearing session.

Functions and user experience:

Momentum True Wireless 3 is quite sophisticated products that features all expected functions that should exist in modern TWS. Besides, all declared functions tailored well in its logics, which is one of the main advantages of having more expensive product from the leading brand. We would like to go over main functions to describe the implementation quality and our feedback about each one:

• Active Adaptive Noise Cancellation: can be activated in two modes (only wind noise reduction or full noise cut off), controlled with the touch on sensor panel (types of tap and channel side can be set in the app). Does really impressive job in full noise reduction mode. No audible change in sound quality but leaves most of the distracting external noises out. Active noise reduction in Huawei, Xiaomi, Apple TWS is definitely less capable (never tried Sony though, people say that it is pretty darn good as well). Of course, if using Momentum 3 only to isolate from the surroundings, without listening to anything, the effect of extra pressure would be apparent. Switching to wind noise reduction only or to transparency mode totally removes possible negative feel. In real usage scenarios, when listening to audio or speaking over the phone with ANC activated to its full potential – you would barely notice any external noises and can totally focus on the sound coming to your ears from IEMs. One note about ANC control: touch sensors on IEM housings allow only to switch between OFF and one of ANC modes (wind reduction, full), whereas the app allows to select any ANC mode in real time and to set which one would be activated with the touch.
• Transparency mode: can be activated in 2 modes (along with audio and activating pause when enabled), controlled with sensor touch (types of tap and channel side can be set in the app) or by the app. Again, app allows to select either of 3 modes (OFF, along with audio, pause the audio) and sets which of the modes would be selected apart from OFF. Similarly to ANC, does a very good job on amplifying surroundings right to your ears. Releases any type of pressure that might annoy during long wearing sessions. Of course, the best effect is when the audio is set on pause, but the incoming voices are quite audible even when the music plays (if it is not very loud). Most of the amplification applied to upper mids rather than treble or lows.
• Multipoint connection: when updated to the latest FW, Momentum 3 can be connected to 2 devices simultaneously. It would allow audio and phone calls from either device, whichever initiates it first. At the same time, we can connect to other devices and store it in TWS memory but only two of those would be active at a time. The rest would be inactive until one or both of the active two would get disconnected. New device pairing process can be initiated by tapping and holding both channels for 3 seconds. Channel LEDs flash red/blue when pairing takes place. The entire list of all stored and currently active devices is shown in the app.
• aptX and aptX Adaptive BT audio codecs: first of all, base or enhanced codec that would be used to play audio with Momentum 3 is defined by the smartphone. If it is relatively modern and supports aptX / aptX Adaptive – aptX would be selected by default with the ability to switch to aptX Adaptive from the app. The difference is mostly vital for lossless audio tracks and respective music player apps that can handle it. aptX is commonly known as 16bit/44.1KHz while aptX Adaptive is substituting more recent aptX HD and bringing 24bit/96KHz, 620Kbps stream with lower latency. Therefore, being almost similar to LDAC and UAT, aptX Adaptive the the best codec currently available for Bluetooth audio – the closest match to the full-frequency quality over the wires. Currently used codec is displayed upon connection in the app itself and under BT connection settings of a smartphone. If aptX is not available, regular codecs like SBC would be used instead.
• Separate use of channels: either left or right channel can be used independently for audio and phone calls. It takes only about a second to activate and synchronize when the second channel is taken out of the charging cradle. The difference between left and right would maintain in types of controls programmed for each one. If some side functions are programmed for the left – the right one would not activate it if you pick it instead. And vise versa. But main functions would remain the same for either one. Another way to control missing functions when using single channel – is to use the app. Both channels equipped with the proximity sensor which means that audio would be stopped or initiated when wearing it. Transparency mode would work and can be manually activated even with a single channel.

It seems that Sennheiser did a great job on developing the application for its TWS products. It is the first time in our practice when the app really helps to see what’s going on and allows to use various additional functions. Therefore, we would like to describe what it is capable of:

The initial screen allows to connect new and see the list of all Sennheiser products that has been located on this device:

First app screen shows the main functions:

• Shows cradle and active channel battery level
• Shows current connection status
• Allows to see the list of connected/paired devices
• Allows to tune and set EQ (it is possible to create own 3-way EQ profile or select one of the presets)
• Allows to run sound check and tune the sound (means running any audio and selecting different presets in special wizard which finally creates your own preferred sound profile)
• Allows to select Transparency mode and to set which one would be activated with the touch
• Allows to select ANC mode and to set which one would be activated with the touch
• Allows to create sound zones based on the location (activating functions in different GPS locations)
• Allows to set touch controls for each channel

Discover tab is for the product and interest related news feed

Settings tab:

• Allows to see and update FW version: updates take about 12-15 minutes, no matter whether earbuds are placed in or outside the case. LEDs would flash green/purple during the process until finished. Smartphone should stay in the area of BT coverage.
• High res audio mode: allows to force aptX Adaptive codec if supported by a smartphone
• Smart pause: allows to set music on pause when either one of the channels is removed
• Allows to automatically accept calls: picks up the phone if any channel is removed from the cradle
• Sets auto-power off interval when removed from ears but not placed in cradle
• Activates and deactivates tone & voice prompts
• Shows currently used BT audio codec
• Displays model name
• Allows to select app language
• Allows to select tiles (functions) that would appear on the main app screen
• Allows to perform factory reset
• Allows to send user feedback
• Lists FAQs and short help on different functions

Pretty powerful and informative application in comparison to most of the app from other vendors which are used once per quarter to check if there is an update. You would definitely use it for ANC, Transparency mode activation, EQ tuning along with FW updates or new device connections. For example, Huawei TWS app feels too heavy and slow with its smart hub and plugins. Moreover, it is not that informative. You visit it once to learn how to control TWS and never go back. Better to skip Huawei updates as well – the last one made ANC almost unusable (non-existent). We’ve already had one FW update for Momentum True Wireless 3 – its changelog was clear and promising as well as the final TWS performance became even more comfortable. We think that such consistency and wise approach from Sennheiser would remain and this is another valuable side of purchasing products from a leading brand.

Momentum True Wireless 3 audio/voice quality:

We’ve tried Momentum 3 with Xiaomi Redmi Note 8 PRO, Windows 11 E14 ThinkPad Notebook, Hidizs AP80 Pro DAP and Xiaomi Qin F2Pro. There were no problems with connecting to either one of these devices; discovery process and connection went fast. Connection keeps stable within one room and shows rare frame drops behind 1 concrete wall. For example, Huawei TWS start to loose the connection when smartphone is placed in back pocket. Nothing like this with Momentum 3 IEMs.

Voice pick up quality is great, responders say that my voice sounds naturally, clear and close to the mic. There were no problems with environmental noise during calls either. Wind noise / evenly spread noise is reduced to the point when the responder doesn’t notice it at all, only some sudden and sharp sounds might break in. Considering all that said, our worst expectation about possible bad quality of voice pick up due to physical shape of IEMs faded away.

Now, about the music: years and hundreds of tests of wired IEMs made us very sensitive and demanding in this respect. Earbuds (apart from some very rare ones like certain Smabat or Ourart models) don’t work at all even when connected with wires. Therefore, similar types of TWS definitely fall short of sound quality expectations adding BT codec problems over its physical fit problems. As to IEM-type TWS, we’ve found the direct relation between the size and shape of channel shell and its resulting sound quality. TWS IEMs with long-protruding leg (battery and mics inside this leg) and small-sized shell sound pretty similar to each other: mostly focused on middle part of the spectrum (which is logical for better voice pickup), with limited abilities on both ends. Tight speaker chamber and insecure fit cut the lows, while BT codecs (especially regular ones like SBC or AAC) severely affect treble. Momentum 3 is addressing both issues with large speaker chambers and the most enhanced BT codec so far. At the same time, more secure fit and much better passive noise isolation creates more linear AFR feel, with even spread across the entire range. Bass is present, pleasantly wide and deep, feels much closer to some regular, wired high-quality dynamic IEMs. Middle section and mid bass sounds dynamic and rich, although a little bit shallow to our liking. Better for linearity but leads to kind of congested stage. Treble is pretending to be extended and bright but still not this airy, sparkling and natural as we got used to with wires. Instrument separation is moderate, stage is pretty small. Resolution is surprisingly good for bluetooth IEMs throughout the entire range. In fact, the good thing is that in overall Momentum True Wireless 3 sound quite balanced, pretty warm and accurate. No will to take if off and switch back to wires. Which is the most important for us.

Comparing with Huawei FreeBuds 4i:

Different shape result in different sound. Huawei is not doing that good in any respect. Fit, passive noise isolation are much worse. ANC performance is not good at all with the latest FW update. Sound is focused mostly on mids.

Comparing with Xiaomi Buds 3T Pro:

Slightly better than Huawei but similar problems with ANC. Moreover, the app is not that useful – feels less consistent. Sound is close in its nature but lacks the extension at both ends as well as the balanced feel of Momentum 3.

Comparing with Divinus Ostia:

Ostia are great TWS IEMs for music. Apart that it neither features ANC, nor the transparency functions. Much less functional but pretty good for audio purpose. Sound is very close and we would say that even more accurate on treble, although not that extended on lows.

Comparing with FiiO UTWS2 + HiRes IEMs:

If to compare like this, you should understand that BT ear hooks would never be as comfortable and cannot stay for long time with you as a result. One hour is ok, but not for the whole day. At the same time, it is the best sound quality what we can get in comparison to wires. With UTWS3 we can use any of our preferred IEMs while BT hooks would work with the latest BT codecs like LDAC. What really suffers in such pair is the quality of phone calls (mics are less sensitive, ANC is not present). Moreover, we had some slight problems in synchronization between 2 channels after short periods of using single one for calls.

Conclusion:

Despite that we are still not convinced that Sennheiser Momentum True Wireless 3 IEMs can totally satisfy audiophiles, this is definitely one of the best TWS on the market. All of the declared features and functions work perfectly, assisting app is great, ANC and transparency modes are very effective, sound is linear and balanced, voice calls sound natural, fit is secure… Even touch controls and proximity sensors behave precisely. All chances that Momentum 3 would become everyday companion no matter the surroundings – loud, extreme or calm. One of our main conclusions is that the overall Momentum 3 performance clearly defines its price and demonstrates the might of Sennheiser brand. So many details are polished and so satisfying is our user experience. Great modern product.

*This review is based on the review of the first version on Hidizs AP80 Pro with the additional findings, highlights and details of the PRO-X successor.

For the last few years I’ve been observing how Hidizs has developed from a small domestic single-product company to the international and respected portable HiFi gear brand. My experience covers each single piece of their audio technology: AP100, AP200, AP60, AP60Pro, AP80 DAPs, all IEMs, cable DAC converters, stand alone DAC, etc. Can’t state that all of those had flawless performance but none has fallen short of expectations in terms of audio quality. Still love my old AP100 and still use AP80 as the most convenient one. Furthermore, Hidizs was the first to utilize HiBy OS with its excellent HiBy link option which has become a golden standard for various current DAPs from other brands.

Today I would like to review Hidizs latest incarnation of very popular AP80 DAP series — AP80 PRO-X. There were couple of revisions of AP80 in the past, mostly dedicated to physical user experience, but AP80 PRO-X inherits the best features of its predecessor (AP80 PRO) and makes a huge leap of completely different nature — Pro version brings balanced circuit with the additional 2.5mm audio output and more power to drive higher loads…

Hidizs AP80 PRO-X technical data (differences / advantages over the previous AP80 PRO are in bold):

• CPU: Ingenic X1000
• DAC: Dual ES9219C
• Decoding: DSD64/128/256, PCM 384kHz/32Bit

• Buttons 3 physical: play/pause, previous track, next track
• Maximum Storage Expansion: 512GB with MicroSD
• Battery: 800mAh 3.7V Li-Polymer Battery
• Work time: PO interface: 8-11 hours runtime, LO interface: 6-8 hours runtime (depends on actual usage)
• Standby: 40 days (depends on actual usage)
• Charging Time: ~ 1 hour (5V, 2A)
• Net Weight: 72g

Going through new specs it is clear that the main change between AP80 PRO and PRO-X are next gen dual DACs (much better channel separation figures, less battery consumption in running and standby modes), better MQA support (8X unfold instead of 4X). Power output has not changed – 190mW per channel on BAL output.

It also happens so that I currently have both versions of this player and would be able to compare their musical and functional performance with similar IEMs.

Packaging and design:

Many visual changes in that part. The box stayed similarly cute and small but it is now more appealing from a glance since containing glossy product graphics, more trademarks and initial information imprints. The insides are similarly well protected and neatly packed.

First goes soft podium that holds AP80 PRO-X, the rest of accessories in their boxes rest underneath. Here you would find:

• AP80 PRO-X DAP with front and back screen guards pre-applied
• USB type-C -> USB A cable
• USB type-C -> microUSB cable
• 2 additional front and back screen guarding film
• couple of leaflets

In contrary to its predecessor, there is no silicon case this time. I am not too upset since I wasn’t very happy with the case quality but I wounder why has Hidizs removed it from this bundle… Perhaps the new design has its own consequences…

More appealing and significant changes found in AP80 PRO-X housing design compared to its previous version: it got even more complicated and definitely consumes even more CNC machine time. Right side edge acquired additional curves and edges that visually lead us to the main element – ALPS volume encoder. It now sits pretty tight, with no apparent rattle or free play. I would say that AP80 PRO-X design is now over complicated for such portable device and starts to remind about A&K shapes.

Left edge displays carries “designed for Hidizs” text which probably means that Hidizs has turned to a new, more advanced design company, which has managed to keep familiar look, bringing some fresh details at the same time. The rest of its virtues remained the same — beautifully looking back covered with stereoscopic glass, intuitive controls, shiny flanges, comfortable physical buttons with tangible clicks.

Screen size and performance didn’t change at all. It is the same 2.45″ IPS  touchscreen with more than enough resolution and sensitivity for this type of a product. It behaves perfectly, has wide viewing angles and enough brightness to interact with it outside, even in the bright light environment.

Performance and UI:

AP80 PRO-X is based on HiBy OS 3.0 and Ingenic X1000 CPU. This combination stays unchanged since the initial release of AP80 DAP and still demonstrates smooth behavior of the user interface. First scan is very fast even with 128GB cards full of different format tracks, all operations are quite snappy.

Seen couple of interface freezes when scrolling through large list of songs but 99% of other interactions are naturally responsive. Haven’t spotted any FW glitches with the latest 1.0 FW version, neither found any severe bugs or translation errors among function list. If you are using any smarpthones based on iOS or Android — you’d feel like being home. Each feature or program is represented by a separate icon.

All general device and audio settings are gathered in Settings Menu, whereas all deep and more precise audio preferences like EQ and filters are located only in HiBy Music application. By the way, HiBy Music looks very similar to its versions for other platforms. No surprises here.  It also features such function as HiBy Link that allows you to control this DAP from a smartphone.

Should say that the pedometer function was not reliable in AP80 PRO-X, don’t see much changes with the AP80 PRO. My Amazfit GTR2 watches show more steps for the similar period. Therefore, I wouldn’t use this function too much. The rest are working as it should.

In order to update FW: we have to download FW from Hidizs website, unpack it and place update.upt file to the root of SD card. Than run FW update from System menu. It would take about a minute to get it done.

One of the most convenient function of HiBy OS — HiBy Link — that allows  full remote control over HiBy Music player from a smartphone works great. Album covers, song list, play mode, volume — all major functions can be controlled from a smartphone. Love this function that makes AP80 home audio integration and remote control in such user case very convenient.

USB DAC:

I always check this function and spending some time watching live or recorded concerts on Youtube or other platforms. Short audio lag and good driver is what I would chase in this test.

USB DAC mode works perfectly either with the dedicated TUSB (ASIO) driver available at Hidizs website or with the native Windows 10 driver (USB DAC). But note that ASIO version might produce more audio lag which would not be very comfortable for watching videos. USB native DAC driver is completely free of this lag. There is no problems in video to audio stream synchronization while watching videos and sending sound through AP80 PRO-X to phones. Neither there are any problems of using it with Foobar2000 player over Wasapi (event or push).

Using AP80 PRO-X as external DAC for Xiaomi Redmi Note 8Pro smartphone with the provided microUSB type-C -> microUSB cable works fine. HiBy Music app recognized this device and allowed us to send bit-by-bit perfect stream.

I have also checked such rarely used function as «transport»: sending digital audio stream though DAP USB to another DAC USB that drives home audio system. Even this scenario worked as expected.

Same scenarios of sending / receiving stream may also be used over bluetooth. So called bidirectional bluetooth DAC. Bluetooth supports aptX, LDAC and UAT codecs (along with lower audio quality standard codecs). I’ve been able to check aptX IEMs and UAT 1.2M device (HiBy W5 bluetooth receiver) — both worked fine while sending data from AP80 PRO-X. The distance was about 8-12 meters away before audio started to show some severe interruptions. The other way around was checked by sending audio stream from Redmi Note 8Pro to AP80 PRO-X over Bluetooth — no problems there either.

Audio quality:

First, I would like to share AP80 general impressions and than I would compare it to AP80P PRO and AP80 PRO-X by pointing out the changes. Such approach is logical because 3.5 audio output has not changed at all (or there are only subtle changes). Therefore, the main difference and new experience would come from balanced 2.5mm output. To keep this comparison precise, I’ve used AP80 + Hidizs Seeds 3.5mm V|S AP80 PRO and PRO-X + Hidizs Seeds 2.5 balanced IEMs. So, similar IEMs with different types of connection, same settings, same audio material.

Initial AP80 impressions: 

What I like the most is that AP80 sounds neutral with slight tendency towards bright/cold tonality. Lows, mids and highs are in good balance making this DAP universal to feed it with any kind of music genre. I would call it a precise source for connecting any further audio equipment like headphones, large power amps, active speakers, etc.

Good clarity and crispness on higher frequencies with the further ability to switch filter effects; precise texturing and presence of lows; powerfull, fast and punchy midbass; natural sounding at midrange with pleasing vocals and its weighted presence in the entire mix. ATH-M50 40Ohms load is easily driven by AP80 creating the feel of mature and balanced sound picture. Price niche (in comparison to more expensive DAPs) is only evident on higher frequencies (simplified, slightly rough, not that gentle) and overall texturing (not that over detailed).

The signature is a bit on the brighter side, no moody or tube-like performance, no cattle effect. Bass is completely enough to hear its nuances with ATH-M50, at least. Neither I’ve found the disturbing presence of sibilance in highest octave. Besides, I didn’t even try to play with HibyMusic MSEB feature that gives additional control over such aspects as:

• sound temperature
• bass extension
• bass texture
• note thickness
• vocals
• female overtones
• sibilance LF
• sibilance HF
• impulse response
• air

all of that was kept at default settings during out tests and the resulting sound didn’t require any changes. But the availability of such features, along with gain and filters, gives you a huge field for further experiments of tuning this source for the final audio equipment in chain.

Channel separation is better than entry-level models demonstrate but not so distant as in case with flagship DAPs or AMPs with coupled DAC chips. The resulting sound stage width, depth and instument location is equal or even a bit more than we would expected from such portable device. Monaural recordings show good distance and instrument placement on stage with clear horizontal and vertical position.

I also tested AP80 with Hidizs Seeds IEMs and found that they make a great pair. ATH-M50, sometimes, might emphasize low frequencies and are very straight forward. Excellent for detail analysis and tests but too strict for getting some rest… Seeds IEMs are softer, warmer and smooth. They create the additional fluency while maintaining the same amount of details.

If to think about the best pairing: I would say that using AP80 PRO/PRO-X with tube amp like xDuoo MT601/602 makes a great effect of smoothing out timbre and tonality, making music more calm and delicate.

AP80 SE V|S AP80 PRO Balanced output: 

The main advantage of using AP80 PRO/ PRO-X balanced output instead of AP80 3.5 SE is the amount of power it produces which inevitably leads to more juicy presentation, more dynamics (especially in midbass section), more clarity and transparency in overall.

Of course, this difference only becomes apparent with high impedance headphones or IEMs which require more power to be driven to an appropriate level. If pairing both DAPs with the same low impedance | high sensitivity IEMs the differences in sound get less apparent… Perhaps, the main difference is better instrument separation and larger imaginary stage. In other words — I like balanced output sound more due to extended assertiveness in combination with less cramped feel under the same circumstances. Difference between PRO and PRO-X alone is not that evident, at least I cannot spot such.

Freedom to choose more demanding output head gear and having enough power in reserve under the hood — this what makes AP80Pro superior to its predecessor even if the changes in audio signature and characteristics are on the subtle side.

The difference between PRO and PRO-X alone is not that evident. Perhaps the stage became wider (at least it seems so to me). But in overall, sonically, both versions sound very similar and I wouldn’t be able to distinguish between them in a blind test.

Conclusion:   

Since the first day of arrival the initial version of AP80 became the main portable source of audio for me and was serving its role perfectly up till now. There were some bugs at the beginning which were eliminated by Hidizs with the new FW releases. The only arguable spec was its output power resulting into a range of final gear limited to a lower impedance.

AP80 PRO-X, being the latest generation, takes a huge leap and represents the most of the ultra-portable HiRES DAP nowadays. It inherited all the virtues of all previous generations, also comes with more polished and stable FW, incorporates huge amount of modern features and visually appeals too. It is balanced, powerful enough to drive all types of IEMs, earbuds and even some large overheads. Can’t even imagine which other new virtues would Hidizs introduce in the next generation in case if AP80 PRO-X is planned for future upgrades. It is already hell lot of powerhouse in a such tiny package. Perhaps – only the modern 4.4mm BL output is desired, although it is hardly possible due to tight space inside (you can check my AP80 teardown article LINK)

And the last, but not the least – should anyone upgrade from AP80 PRO? Only in case if better MQA handling is vital. Otherwise – probably not. But shifting from regular AP80 or something like Shanling M0 is a must. AP80 PRO-X is just so much better in all aspects.

Thank you for reading.

As TWS victorious march on mass market continues, even highest audio quality focused individuals (as us) are sometimes turning their heads to see whether wireless technologies are getting closer, or to find the most convenient compromise for a regular use. Large amount of TWS options that are currently available for purchase are always divided in three segments (at least in our heads): utilitarian TWS, musical TWS and wireless buds that would never serve a purpose for an audiophile (like Apple EarPods) due to its shortcomings in physical design and lack of latest high-grade codecs. The rest of the two can draw our attention but with lots of “if”.

Currently, we have came up with the following conditions for each of two types:

Utilitarian TWS: best to be high-quality earbuds with detachable cables (Ourart ACG, etc) accompanied by high-quality Bluetooth modules (like FiiO UTWS3, etc). In this case we are getting the most of audio quality with the latest BT audio codecs, ability to detach and change earbuds, good quality of phone calls, and the last and most important – buds are not creating vacuum and don’t make you feel uncomfortable throughout the day.

Musical TWS: it should be high-quality IEMs with latest BT audio codecs, with excellent fit and ergonomics.

Now, when we have defined TWS types, we can introduce our new review topic and try to define which type it belongs to…

DIVINUS OSTIA (DVT-100) – TWS IEMs from quite new brand that has some essential peculiarities: first, it is from South Korea (R&D and QC are domestic), second – it is based on in-house DD driver and third – it is music-oriented TWS. Here is the link to official product page: LINK and here is the page to read about DIVINUS brand: LINK

OSTIA tech specs:

• IPX7 (perfectly finished housing protects product from water)
• Light weight, compact size, total weight 39.1g including charging case
• Custom designed DV1 driver (6mm DD Driver)
• Bluetooth 5.0 connection with TWS
• C-type charging port
• Wireless charging
• 20 hours of total usage time, 5 hours playtime per charging
• Voice assistant
• Touch control
• AAC/SBC codec supported
• In-ear type earphone

Official AFR:

The most interesting parts in OSTIA specs is that it has IPX7 protection and wireless charging built in to its charging cradle. Although, no charging base is included. Furthermore, the absence of HD audio codecs makes us doubt its audio performance which we would describe in the sound quality section.

DIVINUS OSTIA available for purchase here: LINK

Packaging and design:

OSTIA comes in pretty small box that contains product graphics and information. Inner part of the box is split into two parts: one holds the cradle with IEMs inside and the other contains two boxes with the accessories. The full box package consists of the following:

• OSTIA cradle
• OSTIA IEMs
• 3 pairs of silicone ear tips
• USB type C charging cable

Along with this set, we have received a set of memory foam ear tips and a set of sound filters. As we’ve understood, those two are the options and can be purchased separately. We would say that sound filters should actually be a part of the product bundle since those act as a dust protection and significantly normalize sound performance on treble… Absolutely a must for OSTIA TWS.

Both OSTIA cradle and IEMs are very compact in size and lightweight. Perhaps, the smallest cradle so far among all we’ve seen. Everything here is made of plastic with the main design element in a form of polished plate with shiny silver DIVINUS brand logo at the top/facing side. Cradle exterior is equipped with 4-segment LED charging indication, type C charging port and integrated carrying lace. Inner compartment has separate L/R IEM beds with magnetic charging pins.

Magnetic force is enough to keep IEMs at place when cradle is opened and held up side down. Despite its low weight, cradle battery capacity is enough to charge a pair of IEMs 4 times. Considering that IEMs can last for 5 hours per charge, it gives around 20 hours of playtime in total.

OSTIA IEMs shell is made of two perfectly aligned parts. Each channel is equipped with a mic under aluminum grill, channel indication, multi-color status LED, compensational opening, charging contacts and sound output nozzles. As mentioned before, nozzle opening are not protected by any means out of the box and require optional sound filters to be fitted. Shape of the nozzles is regular which makes it possible to use any common after market tips. Facing sides of each channel represent touch control sensors. All commands are listed in English user manual. Here we should state that most of the expected controls are embedded (start/stop, back/forward, pick up/hang up), except the volume. It adds some inconvenience since the volume can only be controlled from a source.

Fit:

OSTIA IEMs have good ergonomics and excellent universal fit. Nozzles are long enough, tips provided in 3 sizes and the weight is very small. No problems with the fit even during active movements. Moreover, considering that it has IPX7 protection – no worries about sweat or rainy conditions.

In use:

OSTIA cradle and IEMs takes the charge from empty to full for about 2 hours. Can be charged simultaneously. Pairing is initialized when IEMs are taken out from the cradle and there is no known source is available to connect to. Switch off happens when IEMs are placed back to its place. Each channel can be used separately or in pair. This logics works seamlessly, no problems met with Xiaomi smartphones as a source. Although, there is no multipoint connection function which means that IEMs would produce sound from only one source at a time. On the other hand, it would store multiple device in pairing memory for lighting-fast connection to any previous one.

Touch controls and voice assistance work as expected, quite smooth and reactive. The only inconvenience with that might appear when removing and fitting IEMs from you ear – accidental single touch of facing plate might occur which would result in music start/stop or call pick up/hang up.

Mics are doing a good job in phone calls. No bad response from other party during calls in office or home environment and some light noise interruptions outside.

In overall, we like how OSTIA TWS are made, feel and perform in everyday usage scenarios. FW and logics made good, no errors or flaws in the performance, fast and stable connection and seamless IEM swaps.

Sound quality in comparison…:

Due to the brand background and declared product qualities, we were expecting OSTIA to be musical enough to keep on par with IEMs with Bluetooth hooks combination or with musical TWS like TFZ X1, at least. And it appears to be somewhere in between. Bluetooth hooks like FiiO UTWS3 that support AptX codec, have dedicated amp and based on more advanced elements are several steps ahead of OSTIA in terms of sound quality, especially in retrieving textures /depth on lows and clarity / extension on treble. FiiO modules also bring more details and overall resolution over entire range and better dynamics / articulation in mid bass region. OSTIA feels more tending to show it V-shaped nature with excessive accent on treble and bass areas, lacking maturity and naturality on mids. But mind that FiiO UTWS3 were paired with such great examples of DD IEMs as Hidizs MS2, for instance. Such bundle has much higher price and much less convenient in everyday use.

If to compare to TFZ X1 – another musical TWS with very similar specs – OSTIA keeps up very good and has some significant advantages in sound and overall performance. Sound wise, OSTIA is doing a better job on lows – extension is better, bass sounds deeper and more pronounced in overall. Treble is much closer in its performance, but slightly more delicate and less abrupt and straight-forward. Mids are quite similar, shifted back in both cases and emotional due to tendency towards upper mids area.

In overall, our conclusion that the sound quality of OSTIA is quite far from the best wired DD IEMs which we’ve got used to but its performance as TWS for everyday is very good. Sound quality in such scenarios is totally enough and what is the most important – user experience is close to perfect.

One more word about optional sound filters – it is a must for OSTIA IEMs. Treble section gets quite lisping with no filters attached.

Conclusion:

The main conclusion for us is the proof that Bluetooth TWS are still a good option for general usage, but yet too young to play on wired audio IEM ground. On the other hand, OSTIA definitely belongs to TWS vanguard with the best user experience due to its stellar functional performance, excellent fit, convenient operations and good sound quality. It has the advantages in sound and logics over some more popular brands even despite being quite new to the market. Almost flawless first attempt, worth of attention for general use even on highly saturated mass-market. Audiophiles pass by, but less sophisticated listener should appreciate.

Since the first encounter with devices by FiiO we had a strong feeling of playing with something accomplished, well put together to the extent that missing some additional functions fade away under the tons of positive experience of working with such devices. At the first glance FiiO products doesn’t scream of its superiority in the related niche, but when digging deeper suddenly comes the understanding that there are lots of interesting functions wisely developed and perfectly integrated inside its logics. Recent FiiO UTWS3 (universal Bluetooth ear guides) with its totally revised functionality became the revelation for us for its stellar performance, now comes another Bluetooth device – BTA30 – which leaves pleasant aftertaste and becomes a part of Hi-Res setup.

FiiO BTA30 is a desktop USB DAC. Although, despite being able to accept and process audio data over USB, its main purpose and virtue is to act as Bluetooth audio transceiver. Not only it received Bluetooth audio, decodes and converts it to analog on RCA outputs but also is able to pack and send audio data over Bluetooth. Anyway, details would show up later in this article, let’s go over device specs first:

FiiO BTA30 specs:

As seen from the list above, Bluetooth part is based on mighty CSR8675 (5.0) and supports most sophisticated codecs such as aptX HD and LDAC. Not many standalone or portable devices, apart from Hi-Res audio players or expensive DAC/amps, would license SONY LDAC codec and have this feature. Moreover, in case of BTA30 it is bidirectional – those codecs are also used to pack and send audio data to other Bluetooth equipped devices. Furthermore, instead of using DAC abilities of CSR8675 chip, FiiO processes audio through AK4490 DAC, CT5302 DSP and uses OPA1662 as operational amplifier. Such architecture is far more superior than using Bluetooth chip alone which results in much more resolving and accurate sound competing with many Hi-Res DAPs.

Packaging and design:

FiiO BTA30 comes in relatively small box with outer cover and stiff inner base. Cover contains prints of the product, logos, technologies, trademarks and company contacts. Besides that, there is a counterfeit item protection sticker at the top right corner at the back.

Soft foam insert securely holds BTA30 inside, all accessories are located in a separate box underneath. Full list of items in the box:

• BTA30 with antenna
• 2 protective caps for optical ports
• 4 extra rubber legs (stickers)
• USB A – USB type C cable

What is missing in this bundle is a power adapter. Supposing that BTA30 would be commonly used as desktop Bluetooth transceiver, it would require external USB power. Since it can be powered with any source device over USB, we would recommend to use any adapter with 5V, >=1000mA output and better if it would be linear (for less amount of interference).

FiiO BTA30 design is perfectly clean and accurate. Perimeter unibody frame acts as a chassis for top glass and bottom plastic covers. Facing edge is not overloaded with the control elements, labels are neat.

Here you would find main power and Play/Pause (Pair) sensor buttons along with MODE 3 positional slider switch and smooth volume control knob. Back side is responsible for all inputs/outputs (USB type-C, separate optical IN/OUT, combined coaxial IN/OUT, Line OUT) and antenna. By the way, top glass panel is covered with protective film from the factory. Bottom cover equipped with 4 silicon legs which hide chassis screws.

Personally, we love this kind of neat design with high quality crafting of each element. Everything is accurately assembled with no gaps between main body parts. Nothing rattles and squeaks.

Device in use:

One note for the future users: since the antenna is detachable and has female SMA port, not only we can remove it, but also there is a possibility to enlarge the distance of Bluetooth reception/transmission. Stock antenna is ~2 – 2.5dB whereas most of the current home WiFi routers would use 5dB instead. Such 5dB SMA antennas for 2.4GHz would also fit this unit. Although, as a rule – never switch Bluetooth transmission mode ON when antenna is not attached. This might burn RF amplifier elements. It is better to always use this device with the antenna in place.

There are a lot of usage scenarios, thanks to the functions integrated to this outstanding device. We would point out each one:

• As desktop DAC/preamp for active speakers or home audio setup. In this case we can connect BTA30 from any audio source over USB/COAX/Optical and use Line OUT (DAC MODE).
• As wireless transport for other DAC – connecting audio source over Bluetooth and sending this data over COAX OUT/Optical OUT (BT RX MODE)
• As wireless receiver for active speakers or home audio setup – connecting audio source over Bluetooth and using Line OUT (BT RX MODE)
• As wireless transmitter for Bluetooth devices – connecting any audio source over USB/COAX/Optical and sending data over Bluetooth (BT TX MODE)
• We can even build a wireless bridge (if we have 2 BTA30 devices) – one BTA30 would be in BT TX MODE and taking data from any source over USB/COAX/Optical and the other BTA30 would be in BT RX MODE and sending data to any source over COAX/Optical or just converting and amplifying through LINE OUT.

In those scenarios which do not require source to be connected over USB – we should supply power from a separate power adapter.

Most of the operations are straight-forward. Supplying the power and pressing power ON/OFF switch at the front would indicate in device power state with a dedicated LED. Press once to switch on and hold a bit to switch off. Constant emerald – power ON. At the same time, LED above Play/Pause button would indicate other states according to the position of MODE switch and audio sampling rate. It would request pairing with fast change between GREEN and RED, active connection with single or double GREEN flashes and different other colors for sampling rate (look at the table above).

In case of USB connection, BTA30 would identify itself as FiiO BTA30 under Windows 10 environment. We haven’t found any ASIO drivers on FiiO website and this device is natively supported in modern OS. Although, the output quality in device functions are limited to 16bit/48kHz. Optical and coax inputs would process much better quality (24bit/96kHz optical and 24/192 + DSD64 DOP coaxial), pack it to or unfold it from Bluetooth data or just decode for Line OUT. So, to get the most, it is really better to use BTA30 as DAC with Optical / Coaxial inputs/outputs or Bluetooth.

In case of Bluetooth – it gets more interesting. Not only you can pair with BTA30 from any Bluetooth equipped source, but you can also use FiiO Control APP for Android/iOS and have the additional tuning and functionality. Here is the list of what this app can do:

• Change status indicator light colors / disable it
• Auto-power on function
• Select Bluetooth codecs for TX and RX modes
• Select DAC inputs
• Select between 4 LPFs
• Adjust or fix volume
• Adjust source volume
• Change channel balance
• Enable digital upsampling
• Select streaming quality of selected codec
• Show the guide
• Change device name
• Reset pairing
• Clear settings to defaults
• Power off the device

Moreover, this app works with BTA30 even if it stays in DAC MODE.

We had no problems with sound hiccups or any kind of interference with the stock antenna connected to a regular smartphone 10 meters behind 1 concrete wall. Strong reception/transmission quality that can be improved with third-party antennas. Audio lag while streaming video from a smartphone is present but not large and comfortable. What the the most important – the output power of BTA30 (3Vrms) is totally enough for active speakers to sound very loud. Many current portable Bluetooth receivers are not capable to supply enough power and active speakers would increase noise floor when trying to a amplify incoming signal to an appropriate level. Absolutely not a problem for BTA30 and this is one of the main reasons why BTA30 suits out setup.

Pairing is fast, further connections are lightning-fast. No clue about multipoint function (seems none) but BTA30 stores more than 5 different devices (which we’ve tried so far) in its memory and connects to the first discovered after enabling Bluetooth on anyone of those. No need to pair previous devices again.

Since there is a choice of TX or RX modes for Bluetooth, we cannot simultaneously receive audio from a source and send it to the end gear. Such capability is met only in some recent feature-packed DAPs.

Volume knob feels nice and smooth, has special surface finish to add some additional grip and utilizes full mechanical travel. It can be disabled through FiiO Control app.

Since there is no battery inside – we should not be worried of leaving BTA30 ON or on charge. Nothing heats up, nothing drains down.

Sound quality:

To carry out adequate test we have decided to describe the sound of BTA30 in comparison to other desktop DACs/amp such as Tempotec Serenade iDSD and Hidizs Sonata DH1000.

Speakers: Edifier M1100.

Lows and midbass:

BTA30 is quite resolving on lows – more than average amount of textures and details. It acts on bass delicately with good control on outlines and good balance with other ranges. Extension of lows is very good, bass is decaying neither too fast or too slow. Great clarity, good volumetric feel and separation from mids and treble. Bass is totally perceptible, enlarges the stage and has no extra emphasis. Mid bass is similarly good: the amount of dynamics is perfect for good articulation and energy.

Mids:

Mids retain most of the resolving potential and sound neutral in overall. Vocals are quite thick and full-bodied. No emphasis is made on female vocals and upper treble range instruments feel naturally bright but not screaming. Voices sound natural and have pleasing warmth. Good instrument separation. In overall, mids feel smooth, little bit warm and natural, with adequate resolution and with no piercing peaks.

Treble:

Treble sounds balanced to mids and lows but its extension, clarity and presence would depend of the type of connection. In DAC mode treble is clear and crisp, not hidden by other sounds. Extension and micro-dynamics are both great, not too cold or vivid. With Bluetooth connection (RX or TX) treble gets slightly less extended and crisp. Like a thin blurring layer has been added to clean window. Nothing strange for the regular Bluetooth sound. In overall, this range is accurate and perfectly balanced to other ranges and allowing long listening sessions.

Compared to Tempotec Serenade iDSD:

Serenade iDSD is not equipped with Bluetooth and can be used only as DAC/preamp or amp for the headphones. This makes iDSD and BTA30 quite different in purpose and gives some advantages in sound to iDSD. It sounds slightly better and more extended on treble if to compare BTA30 in Bluetooth mode. It also gives a better understanding of quality of the sound when connecting headphones which is not possible with BTA30. But with the same active speakers, both devices sound virtually the same.

Compared to Hidizs Sonata DH1000:

Another device that is not equipped with Bluetooth and made for portable use with headphones. This allows to perceive sound quality more delicately until connected to active speakers. With this type of connection, DH1000 sounds similarly detailed but more thin on mids, resolving and putting more emphasis on treble. Lows are not that well-developed as with BTA30, thus loosing stage size and extension. It is better to leave DH1000 for headphones only, while BTA30 really shines in desktop setup.

Conclusion:

All of our initial expectations of what desktop Bluetooth transceiver should be were met by FiiO BTA30. It is perfectly built piece of technology, with neat design, smooth operations, lots of functions and good sound quality. Bluetooth performance is stellar due to its sustainability to RF interference and signal quality, the best so far among all tested devices in both TX and RX modes. A spoon of tar is present in a form of limited USB DAC processing ability but it goes beyond the main purpose of BTA30 and compensated by other more capable interfaces. In overall, this Bluetooth DAC/preamp is great and would fit nicely to any home setup, enabling wireless audio feature and incorporating best widely used Bluetooth audio codecs that are currently available.

Another look at Bluetooth wireless receiver from a different perspective (means another formfactor). This market is trending and so many options are available that it is hard to make the right choice from the very first try. We’ve already been playing with TWS IEMs, Bluetooth neckband wires and standalone devices but not the “ear hook” type DAC/amps. Seen those couple of times before on sales but not from a trusted brand or a supplier. Although, such formfactor always looked promising and intrigued with the possible comfortable fit, battery capacity and max. power potential due to a larger compartments and its universality for different types of IEMs. To be honest, looking at the picture of such type of product, we are not making another idol: yes, it should be better than any other all-in-one TWS or Bluetooth receiver in certain aspects, its universality would stay limited to several IEM shapes or connection types and the product would be worthy to try only after it has passed several iterations and came to a stage of maturity…

With all that in mind, FiiO UTWS3 was kind of a surprise – coming from a well-known portable audio brand, full of features and impressive specs. For us, the most important is that this product represents the next iteration with heavy upgrades to its predecessor – original FiiO UTWS (UTWS1). At least, it means heavy usage, collecting feedback, thinking over, bug fixing, improving and upgrading various aspects, both software and hardware which eventually leads to a better product with polished user experience. Whether it is that mature already? – we would tell in the conclusion. Meanwhile, here is some infromation about the company, a small flashback to FiiO UTWS history and the idea behind its new version:

First of all, about FiiO brand in short:

Guangzhou FiiO Electronics Technology Co., Ltd. was established in 2007 by several former senior staff and tech experts of OPPO, which is a high-tech enterprise focusing on researching and developing portable music products, with current main products being Hi-Res music players, headphone amplifiers&DAC, and headphones/earphones.

There are over 300 employees in total, including a core team with nearly 30 years of R&D experience in audio products, an R&D engineer crew dedicated to software, hardware, industrial design, structure and electroacoustics. The production factory covers an area of 3500 square meters, including an all-new updated dust-free workshop and 4 two-way assembling production lines, with an annual production of up to 1 million pcs.

FiiO specializes in self-research and development, and sells FiiO-branded products through sales agents worldwide which cover 5 continents spanning 65 countries and regions. Since its establishment, FiiO has built a good brand reputation in the industry. In Nov. 2017, the Headphone Branch of China Audio Industry Association was found, while FiiO was honored to join and elected to be the vice-chairman; 3 years in a row from 2017 to 2019, FiiO has been on the Top 10 HIFI Headphone and Digital Audio Brand list, as well as Chinese Top 20 Cutting-Edge IP Enterprise and Guangzhou Little Giant Enterprise of Science and Innovation; By virtue of outstanding product designs, FiiO has received 47 valid patents, including 2 invention categories, and countless well-known awards, including iF Design Award, Reddot Award, EISA Award, VGP Award, and Spring/Autumn Headphone Festival Award.

FiiO has been continuously carrying on the music proposition of “Born for Music”, placing great importance on user needs and ceaselessly pursuing perfection in product design and manufacturing, to supply users with the best audio products at the best prices.

FiiO has already been long involved into Bluetooth audio devices and released full bunch of products with different usage scenarios in mind:

• BTR series Bluetooth AMPs (for use with a smartphone, PCs, etc with the regular IEMs or headphones)
• FB1 IEMs with integrated neckband Bluetooth cable
• EH3NC Bluetooth overheads with noise cancelling feature
• TWS IEMs (popular model of the trending market)
• UTWS1 – Bluetooth ear hooks to use with any IEMs

Considering the popularity of UTWS1 (and its shortcomings on the other hand after some heavy usage) – FiiO has decided to give it a new birth when the product would be free of any previous bugs and inconvenience. Initially, UTWS1 were based on the third-party product that already had some hardware limitations in its core. Therefore, the new generation was decided to be given in-house design, research, development and production processes. The main points of concern (i.e. upgrades) during UTWS3 development were the introduction of independent amplifier, significant increase of the output power and decrease in noise floor, more convenient charging scheme and longer battery life, better noise cancelling ability, IPX4 protection, new volume and power cycle logics and dedicated control application. All of that eventually leads to much better ergonomics and user experience. As far as we are concerned, all of the known and reported issues and inconvenience of the first generation UTWS1 were addressed and claimed to be resolved.

To finalize about the difference to its predecessor, here is the full list of upgrades in UTWS3:

• Now uses independent TPA6140A2 AMP
• Power output increase from 5mW to 25mW at 32Ohms
• Noise floor decrease from 25uV+ to <8uV
• No need to charge each channel with a cable, both take charge from a cradle now and charge faster
• 2nd microphone added for better noise cancelling ability
• Added IPX4 environmental protection
• Volume controls better now (26 levels, better physical buttons)
• Power ON|OFF is now controlled with cradle top cover
• Uses FiiO Control app for settings, upgrades and tuning EQ

Done with the history… Let’s get back to FiiO UTWS3. The specs are as following:

• Chip: Qualcomm QCC3020, Bluetooth 5.0
  • TWS+ Low Latency (2 channels connected at once)
  • 2 independent amps

Packaging and design:

FiiO UTWS3 comes in relatively small and visually attractive box consisting of outer cover with product graphics and company information and the inner more sturdy black cardboard insert that holds the product itself. FiiO has added a special sticker on the back side of the outer cover as a solution to counterfeit item protection.

Inner box compartment has a special soft insert that holds UTWS3 cradle at place while the cable, user manual and warranty card are stored in the separate envelope underneath. Not much of the accessories, though. Only ear hooks with the cradle and charging USB type-C -> USB B cable. Wonder why FiiO has not included any carrying pouch for the sake of the product long-lasting protection.

Ear hooks are stored inside the cradle and have special stickers pre-applied to charging pins in order to avoid charging during the delivery. Good way to prevent early battery deterioration before it gets to the end user. Just don’t forget to peel it off before use. Cradle, itself, makes a good impression and feel – little bit rough surface, accurate and even strict design. Someone might say that it is boring due to lack of design elements but we’d rather call it – functional. Lightweight, though, We expected its weight to be much more than it really is. There are 3 LED indicators at the facing side of the cradle and USB type-C charging port at the back. Nothing more.

Top cradle cover opens with little effort, totally enough to keep it at place under any circumstances when the external force is not applied. Can’t tell for sure whether it is retained with a magnet but there should be some kind of element like this that enables power off|on logics for the ear hooks. Anyway, folding mechanism looks to be quite durable and feels natural.

The insides of the cradle look more appealing than the externals – neat ear hook profile cutouts at the top cover and base aided by the combination of grey (scratch protection soft material adhesives) and black colors, deep lodgments designed to store third-party IEMs or earphones of virtually any size and shape. Plus the additional button at the most convenient place that does some vital tricks. Don’t worry, it won’t be used too often, only for some initial procedures.

Apart of the cradle, FiiO UTWS3 ear hooks are much more sophisticated devices that contain all the magic. In terms of a design, they consist of the plastic base and flexible ear guides (perhaps, made of a silicone with inner channel for 20 strands of monocrystalline silver plated copper wire). Both channels have FiiO logos on the facing part along with large, easy to reach multifunctional button.

Furthermore, both channels feature 2 microphones protected by aluminum grills, white LED indicators (same opening with the backside mic), magnetic charging pins, aluminum rings acting as channel indicators (left – blue, right – red) and MMCX or 2-pin, 0.78mm connectors (both versions are available for a purchase). And the weight/channel is only 6.5g (without IEMs). Additionally, since UTWS3 features IPX4 protection, both units have special dust/moisture gaskets protecting button and mic openings.

In overall, the design of the whole set is varying from strict and functional (cradle) to clean and practical (ear hooks) with only few eye-catching elements. But what is unquestionable is the precise manufacturing, perfect alignment of all elements and decent build quality.

Fit:

The main point about the fit concerns the type of IEM connector selected during the purchase. MMCX type seems to be the most universal option since the connector allows IEMs to rotate over Y-axis. It gives certain freedom of adjusting the angle at which any MMCX IEMs would go into ear channel. With 2-pin option, it seems that some IEM shapes might struggle to fit into the ears correctly, especially if the output nozzles are given some irregular angle (that deviates much from 90-degrees). It is only our thought that might not be the truth. But we would really appreciate if FiiO would consider redesigning the connectors. The best option would be to have MMCX ear hooks only + the additional MMCX->2-pin, 0,78mm adapter in a bundle. Such approach would solve 2 issues: it would make UTWS3 even more universal out of the box (no need to choose and stick to connector type) and it would also allow 2-pin adapter to rotate on MMCX connection base.

As to our version – MMCX – we have tried it with different types of IEM shapes (custom, bullet, droplet, round) – all seem to fit nicely. The least comfortable for a long ride were bullet-like shaped IEMs since the physical pressure to ear channel increases when UTWS3 ear guides flex more. This happens when IEM body is quite long, which is kind of rare. Short bullet-like IEMs as HiBy Beans, for instance, do not produce any discomfort.

One more aspect to mention in this section is the type of end gear to use in overall. FiiO UTWS3 is designed to be used on a constant basis, for music or videos, during workouts or simply to talk over the phone. The possibility to use each channel independently also makes UTWS3 a great substitute for a handsfree device. In either scenario that involves long sessions (except music or videos), full immersion with total real world isolation is not necessary and even dangerous. Outer noises should be coming in to save yourself from a possible incident, especially outside. Ok, you can use only 1 channel… But in this case, when only 1 IEM is used – you are risking to get a headache, or worse. Therefore, the best option in such usage would be to use earbuds instead of IEMs. For example, such excellent options as Ourart ACG or Ti7.

Device in use:

Since FiiO UTWS3 is quite sophisticated device it requires some learning of control operations. Initially, you would have to charge the cradle and ear hooks (inside the cradle). It takes time, but all 3 devices take charge simultaneously which is a step up from a previous version where you would have to charge each channel separately. Just wait for all 3 LEDs on the cradle to go off – it means that charging is compete. As soon as the cradle top cover is opened – both ear hooks come into life with auto power on function (power goes off when top cover gets closed) and the initial pairing process starts (center cradle LED flashes white and red). Now you can proceed with Bluetooth device discovery on your source device.

You should be able to locate FiiO UTWS3 L (or FiiO UTWS3 R or FiiO UTWS3 L/R) at this stage and connect to it, responding with “allow” whenever requested. This would result in device pairing with both channels connected at the same time. Compatible sources should report aptX as Bluetooth audio codec currently in use. FiiO UTWS3 is ready from now on. We would also recommend to get FiiO Control app from Android/iOS store to gain full control over this device. This application would allow to:

• check each channel battery state
• check and upgrade FW version
• change button functions
• set idle state power off timeout
• enable and tune EQ
• tweak audio settings and change voice language
• reset the device, clear pairing
• read user guide

By the time of writing this review FiiO has already released the new FW: 0.2.46 which has bug fixes and new volume logics listed in the changelog. The process of upgrading requires that only one channel should be upgraded at at time – means, the second channel should be in OFF state. It takes about 2-3 minutes/channel to upgrade and can be performed with OTA or local FW *.bin file. Further pairing reset and reconnect is also mandatory. Done in the following steps:

1. Place both channels in cradle
2. Press and hold button on cradle for 12 seconds to reset and power off
3. Ear hooks would get back to life automatically in couple of seconds and synchronize to each other
4. Now it is possible to connect again

Other cradle button functions:

• Long press for 3 seconds – enter pairing mode
• Long press for 12 seconds – reset pairing
• Short press – remaining battery in cradle

Indications:

• R and L white LED pulses – ear hooks charging (for 15 seconds with no USB power supply, constantly – with USB power supply)
• R and L white LED pulses go OFF – ear hooks charged
• Central white LED ON for 5 sec after opening top cover of pressing button – cradle remaining battery >20%
• Central red LED ON for 5 sec after opening top cover of pressing button – cradle remaining battery <20%
• Central white LED pulses – cradle takes charge
• Central white LED ON – cradle fully charged
• Central LED pulses white and red – ear hooks pairing in process when in cradle

Left ear hook button:

• Single click:
  • Resume playback
  • Decrease volume
  • Answer call
• Double click:
  • Pause
• Triple click:
  • Activate voice assistant
• Long press:
  • Previous track
  • Hang up
  • Decline a call

Right ear hook button:

• Single click:
  • Resume playback
  • Increase volume
  • Answer call
• Double click:
  • Pause
• Triple click:
  • Activate voice assistant
• Long press:
  • Next track
  • Hang up
  • Decline a call

For both channels when not in cradle:

• In OFF state – press for 1 second to power ON
• In On state – press for 5 seconds to power OFF

Huh… Requires some time to memorize…

As stated in the description, full charge would allow to use each channel for ~5.5 – 7 hours (which is close to real world figures) and the cradle would also allow to fully charge both channels for 5 times.

No problems were met during pairing process, real world usage, charging or upgrading the firmware. FiiO UTWS3 declared functionality seems to be fully implemented and thoroughly polished. Phone calls don’t disappoint either, providing good voice quality and smplartphone-level noise cancelling performance. Buttons do the job as expected and defined above.

Sound quality:

Now, to the most interesting part. Our testing setup would be HiBy R5 Sabre DAP + FiiO UTWS3 + ArtMagic DH3 (15Ohms) IEMs and aptX codec. We would leave out examining sound with SBC or AAC as less capable codecs, not worth of attention if you have already spent more than $500 for the entire setup. Qualcomm QCC3020 chip over AptX, at least, gives you 16bit/48kHz at 384 kbit/s and frequency response 20Hz – 22.7kHz. More than CD quality but not HD yet.

DH3 are hybrid, easy to drive IEMs with only 15Ohms impedance and 105dB sensitivity. It results in ~55mW of power from UTWS3 which is more than enough to squeeze out the appropriate dynamics and volume level. Such IEMs would get very loud, almost unbearable. Anything sensitive up to 50Ohms should be driven adequately.

Since UTWS3 feels quite linear in tuning, there won’t be any accents on either range other than IEMs would produce on its own. In comparison to cable connection, a certain model of IEMs would sound quite similar, with slightly less clarity on treble, slight decrease in overall resolution and texturing. First addresses Bluetooth codec potential that usually strikes the highest octaves, while the resolution suffers from the limited potential of hardware processing packed to a single chip with significantly reduced element base. But this is only in comparison to HiRes DAP as a source. If to compare UTWS3 to a regular smartphone output sound – some of its aspects would even get improved. For example – midbass dynamics.

In overall, UTWS3 lows feel quite collected and contoured rather than deep or extended, midbass has appealing dynamics and power, mids are linear, with moderate resolution and good balance between male and female vocals, lower treble feels calm and delicate while the extension is slightly below the average. We wouldn’t insist that UTWS3 is capable to substitute wire for a quality-aware listener, neither we would say that UTWS3 cannot substitute wire when necessary for any audio fan. Since it doesn’t add any coloration to regular sound of your favorite IEMs or earbuds – it is a good option whenever wires limit your mobility.

Compared to Hidizs H2: completely different formfactor, still portable, much more capable in terms of Bluetooth codecs (aptX HD, LDAC, UAT) but at the same time – more limited in power output and more susceptible to audio lag. Yes, Hidizs H2 has its numerous strong points but FiiO UTWS3 are far better if the usage scenario is portable everyday use. Especially with a smartphone, when you want to answer calls. Sound-wise, both are neutral sources for IEMs and both behave quite similar. H2, of course, has more potential due to HD codecs but cannot drive similar loads as FiiO UTWS3 do.

Compared to ColorFly BT-C1: almost similar to Hidizs H2, ColorFly represents a standalone product with less portability in mind. It is a closer match to UTWS3 due to only aptX codec support and same power output level. It is very neutral, if not to say boring. Mostly designed to be used as a shelf receiver for active speakers. Not a contender for its planned way if use and less appealing tuning.

Compared to TFZ X1: perhaps the closest match of those, but in a formfactor of IEMs with inbuilt Bluetooth receiver. Less universal, limited to only 1 sound character, less sophisticated in terms of functions and much worse during the phone calls. Overall user experience of TFZ X1 is far from ideal – buttons are too small, LEDs are almost invisible, noise cancelling not good. But the build quality is decent, aptX is supported and sound is quite impressive. FiiO UTWS3 definitely wins, thanks to the possibility of connecting different IEMs.

Conclusion:

Perhaps, FiiO UTWS3 is currently the best representative of what Bluetooth TWS product should be like. Polished in a second iteration, free of bugs or limitations, with adequate revised logics – this product provides strong user experience and stellar performance in the most universal formfactor. Neckbands, TWS IEMs, standalone receivers – all would be less capable or portable in everyday use, either not allowing to switch end gear or to perform routine activities in the most convenient way. FiiO UTWS3, with the idea of universal wireless receiver for any IEMs or earbuds, does the trick in a best possible way, providing audio fans with enough quality and regular user with the appropriate level of comfort and functionality. Or the mixture of those, as the most valuable result. We would definitely stick to this product for a long period as the most universal option currently available on the market…

Update: here is the link to our FiiO UTWS3 review: LINK

FiiO has announced a release of significantly revised version of True Wireless Bluetooth amplifier in 3 days. The original news post was shared at FiiO official Facebook page. New product – UTWS3 – is a successor to UTWS1 Bluetooth ear hooks but with numerous improvements in hardware architecture as well as in software functionality and optimization.

The most important is that changes in UTWS3 are inspired by and derived from the feedback of 1st gen. owners that should result into perfect performance and user experience.

Full list of improvements and changes are yet to come, but we can already give a short summary:

• HW part would now include TPA6140A2 independent amplifier
• Better noise floor handling
• Increased power output
• Increased battery life
• Better noise cancelling function
• Device control with special smartphone application

Again – the full list with more details would be available in few days.

Just to remind: FiiO UTWS3 represents TWS Bluetooth ear hooks with 2pin|0.78mm or MMCX connectors to equip any IEMs with wireless audio functionality. Features Bluetooth 5.0 and SBC|AAC|aptX audio codecs.

Our sample is on the way for further tests and review. Stay tuned…

Couple of days ago, together with Black Friday discounts for the entire lineup, Hidizs has announced their new product — H2. My sample unit has landed about a week ago and here is my presentation and in-depth write up of this device.

So, what is Hidizs H2? It is a small DAC unit that is positioned by Hidizs as Bluetooth receiver. Although, its functionality goes beyond that definition. Along with acting as a Bluetooth DAC, it allows USB connection as well. I have already been dealing with other Bluetooth standalone receivers from HiBy (W5) and Colorfly (BT-C1), Bluetooth cables for IEMs (Hidizs H1) and tabletop DAC|amps with Bluetooth audio reception (Audinst HUD-DX1 Blue24) but neither one of those was similarly capable in terms of HD audio codecs support or didn’t have USB DAC function. Of course, H2 is not free of some limitations which would be described here later. For now, my point of what makes Hidizs H2 almost unique is that it combines the support of all known Bluetooth HD audio codec and USB DAC function.

Hidizs H2 specs:

As we can see from the specs published by Hidizs, the supported HD Bluetooth codecs cover Qualcomm aptX HD, Sony LDAC and even 192kHz, 1.2Mbps HiBy UAT. Of course, less sophisticated regular codecs such as aptX, SBC, AAC are also supported.

From the standpoint of HW architecture H2 is based on 24bit|192kHz Qualcomm CSR8675 SoC which incorporates Bluetooth 5.0, TrueWireless, WirelessBroadcast and active noise cancelling cVc technologies (yes, H2 does have a mic onboard and allows regular calls with noise cancelling). Amplification is done on behalf of MAX97220 differential amplifier chip. Although, despite theoretical datasheet power output stated as 125mW @ 32Ω, H2 is only producing 8mW|channel with the same impedance. This is the only arguable specification of this device. Nevertheless, as derived from further tests, it still drives 32Ω to an appropriate level and the rest of the specs remain quite impressive.

Packaging and design: 

Hidizs H2 comes in a small black matt box standardized across most of the product produced by Hidizs. Box contains silver imprints of specs, manufacturer info and logo together with glossy device outlines.

As a matter of fact, this box could have been much smaller in size since H2 is pretty tiny device and consumes just a fraction of the space inside. It is stored in the special top level insert while all accessories are located in another compartment beneath. Accessories include:

• USB type-C -> USB type-C (host|slave) cable
• USB A -> USB type-C cable
• plastic case|clip
• leaflets, warranty card

H2 housing is made of solid piece of resin (German Makrolon) with front and back glass panels. Such choice of material not only looks great and resembles overall Hidizs design principles, but also stays transparent for the radio waves ensuring the best reception quality.

The design looks clean, simple and attractive at the same time. Personally, I admire the approach of placing logos and text behind glass panels — it makes it shine and protects from any damage. Unfortunately, scratches on the panels are inevitable in future due to the absence of protective film. At the same time there are factory protection films from the box but those are used for transportation purposes. The best way, probably, would be cutting off special peel off projections from this film and leave the rest on the device.

Since H2 has NFC module for easy pairing, it contains NFC logo under the front glass panel. Right edge contains power button and 3-color LED, left — volume up and down button. Mic opening and 3.5mm audio output is located on the top edge while USB type-C port is on the bottom. Buttons are not rattling and have a good actuation feel.

Plastic case|clip is a great accessory which is familiar from Hidizs S9 DAC|amp. It is made of transparent plastic with rough surface finish, securely holds H2, allows easy access to all buttons and doesn’t cover mic opening. Clip spring tension is more than enough to be confident that H2 would not get lost during a workout.

Preparing H2 for use:

Very straight forward: H2 requires ~1.5H to reach the full charge and indicates the process with flashing red LED. There are 2 scenarios after that: either to connect H2 to a smartphone or PC with a cable or to pair it with any device over Bluetooth. Second scenario can be achieved by a regular pairing process or by using NFC of H2 for faster identification and connection. Long press Power button to enter pairing mode. H2 would quickly flash blue LED to indicate that the process has started (and would go into slow flashing mode when paired).

When paired with a smartphone, it is better to use HiBy Blue from the corresponding app market in order to monitor connection quality, codec in use,  battery state, use the additional EQ and to be able to upgrade the firmware. Most of the functions of this app are not required if H2 would be used with HiBy Music app over Bluetooth or USB. EQ and audio codec would be pushed by this app instead of HiBy Blue.

By the way, H2 has multipoint function and allows 2 device to be connected over Bluetooth simultaneously.

H2 in use: 

There are different stated of LED that indicate device operation:

• Charging — flashing Red
• Pairing — fast flashing Blue
• Up to 48kHz — slow flashing Green
• 88..2 up to 192kHz — slow flashing Blue

Button functionality:

• Power button
  • Short press — play|pause
  • Long press — on|off
  • Very long press in OFF mode — pairing
• Volume up|down
  • Short press — volume up|down
  • Long press — next|previous track

There are integrated voice prompts for standard functions such as power on|off, connection state and pairing.

Switching between LDAC, aptHD and other audio codecs is done from a smartphone under the Developer options menu. Initially, H2 would be pushed with the best possible supported codec from a smartphone. In my case it was LDAC (Xiaomi Redmi Note 8Pro). Although, in order to switch to the supreme HiBy UAT we would have to run either HiBy Music or HiBy Blue (if other music app is used). The connection distance free of any hiccups for LDAC and UAT can reach up to 10 meters at open space. Even one thin concrete wall is not a severe obstacle but the distance gets limited to 2-3 meters from a wall at one side.

When using cable connection with a smartphone — USB DAC gets recognized and everything works correctly. Bit-perfect mode is allowed be HiBy Music app. The only concern is that the cable has host and slave sides and should be connected in a correct way. Microphone with noise cancelling function works great, allowing to accept and answer the calls. No complaints from the other party in terms of voice quality.

H2 runs flawless in Windows 7,8 and 10 environment as well. The device is getting recognized by the system as Hidizs H2 USB sound card with integrated mic. No driver is needed. Furthermore, there is no driver available from Hidizs till now. The maximum audio quality listed in device properties is 16bit/48kHz what makes me wonder about the possible release of special monopoly mode driver later by Hidizs. Current native Windows driver does not occupy H2 and allows all sounds with no lag in videos. Which is good.

The difference in device operation time from a single charge in Bluetooth or cable mode is hard to tell since H2 starts charging when connected to USB port of any device. Therefore, it would drain source battery before running out of charge. Stated battery life in Bluetooth mode is close real time figures. I’ve got 6,5H battery life of playing audio with LDAC codec.

One good function that should be mentioned is the ability of H2 to play music and take charge at the same time. This allows to stay connected even if the battery has drained. Or to use H2 as Bluetooth receiver in home setup.

Sound quality:

I would not get too deep in this section since my perception of Hidizs H2 purpose is very subjective. The main scenario for me is integrating Hidizs H2 into home stack as a Bluetooth receiver, allowing LDAC and UAT decoding and passing the signal to external amp or active speakers. Such scenario is not that demanding in terms of output power.

Of course, the initial tests were done using IEMs (Hidizs Seeds, 25Ω) and full-sized AudioTechnica (ATH-M50, 38Ω). Surprisingly,  in both cases the audio quality does not disappoint and both models are driven adequately. IEMs with such impedance even have some room to increase the volume further, while full-sized IEMs are just on the edge of H2 potential. This also leads to properly driven IEMs showing better overall dynamics, integrity of lows and midbass, separation of each instrument and more perceptible resolution. ATH-M50 sounds more dirty and tends to leave out some details by mixing instruments together at higher volume levels. But this is expected behavior with such output figures.

In overall, when paired with low impedance | high sensitivity IEMs, H2 sounds clean, while tending to warm sound in signature. It shows moderate amount of details across the entire range, good midbass dynamics and power, pretty thick mids and has no irritating peaks on highs or upper mids. Cable connection delivers better extension and clarity at both ends (especially on higher frequencies). As always. I should mention here that the audio lag in Bluetooth is more apparent which should be considered when watching videos. It is acceptable but close to the point of getting a  desynchronized with the video stream.

To summarize: H2 should not be regarded as a potential competitor for such products as Hidizs S8, S9 portable DAC|AMPs and AP80 DAP lineup — it is not capable to deliver the same level of audio quality due to a limited power output. On the other hand, it sounds more balanced, clean and impressive that a regular smartphone or PC with the appropriate IEMs or in active home setup.

Conclusion:

Hidizs H2 perfectly does the job of HiRes Audio Bluetooth receiver in active home setup by supporting the most sophisticated audio codecs, multipoint connection and simultaneous charge. While in the portable usage scenario the user should be aware of its limited driving ability. Other than that, Hidizs H2 is a good performer with rare combination of Bluetooth receiver and USB DAC functions. Moreover, its implementation and user experience is flawless. Therefore, it is recommended to consider if its main features and virtues fit the desired setup.

Couple of days ago, HiBy introduced a significantly reworked version of quite popular R6 DAP in a livestream event. First version of HiBy R6 was initially launched on Indiegogo back in 2017 and shown high interest of the audience by exceeding campaign target and finishing as a successful project in overall. Later came the R6Pro which had several HW tweaks to improve the performance.

Recently introduced R6 is not just an increment but looks to be a total revamp of the previous generations. According to the shared data and information that was already added to the official website — new R6 looks better, has better ergonomics, based on updated SoC and runs Android 9 OS. Furthermore, audio HW part was also improved to deliver the best possible quality.

Let’s see the changes in table view. Some specs are still missing but the idea is clear:

Together with lots of HW & SW improvements, the design has also changed drastically which claimed to make the ergonomics more comfortable due to new form factor, size, weight and depth. Here are some pictures:

Our own perception of the changes is very positive. We see that HiBy has addressed some issues that users were facing with previous models. Like the quality of WiFi reception, for instance. If the antenna was wisely updated — we can expect much better performance and speed… Same goes to many other major and minor concerns and should make this generation ideal. Hope so…

New HiBy R6 sales should begin in November with a price tag of $799 at HiBy official store.

Stay tuned, more news to come…

Always wanted to have portable HiRes audio setup from a respected brand in which each of the components would be wisely designed and developed, fitting each other in the best possible way, while still staying perfectly usable in standalone applications. Having everything designed by a single brand usually means better integration of the most complicated functions, which creates a synergy that people would often call brand «ecosystem». HiBy has travelled a long way since creating very first parts of such synergy and can already bear some fruits by providing different hardware components run by HiBy OS, music application and with the help of HiBy protocols.

Packaging and design:

R2:

This little DAP comes in a relatively small black box with colorful graphics, trademark information and company contacts. Box is pretty stiff, does a perfect job of protecting this gadget during the transportation. Inner compartment is split to three sections: top soft insert holds R2 at place, some accessories located underneath and one more little box contains USB cable. Full list of accessories is as following:

• R2 DAP
• plastic case
• USB type-C -> USB A cable
• user manual + leaflets

Moreover, R2 screen and back glass panel are both covered with a protective films out of the box. You would only need to peel off the extra protection layer.

This DAP is a small unit but still a little bit larger than its main rival — Hidizs AP80Pro. Chassis are made of zinc alloy with dark edge toning, beautiful glass back panel and large screen at the front.

Сontrol elements have сomfortable size, tight and well pronounced actuation. This, in overall, creates a feel of holding tough and durable device.

Two buttons (Volume + / -) are located at the left edge while three more buttons (Play/pause, Previous / Next) are placed on the opposite side. There is another beautifully designed element at the top — power button — that is encircled by the multicolor LED facing that shows different states and also synchronized to the sampling rate of the currently playing track.

Since R2 is capable of recording audio — it features two microphones that can do stereo recording and cancel out some significant noise. By the way, this function works perfectly, also allowing to choose the audio quality of the recording and the resulting file format.

Screen is definitely a virtue of R2 — 2.45 inches, IPS, vivid colors, good factory calibration, having snappy response and precise touch sensor positioning. Maximum brightness level is totally enough for outdoor use in a shade and little beat weak for sunny areas. Crispness and screen density are perfect for such physical size.

The only arguable part of this gorgeous screen is a quite large width of upper and lower frames. While it seems that frames are almost absent in power off state (borderless) — everything becomes clear when the screen becomes lit. Sides are almost touching the edges while upper and lower frames are unexpectedly wide.

Bottom edge contains USB type-C port, 3.5mm SE output and microSD card slot that supports up to 2TB capacity.

Semi transparent plastic case is a great accessory that protects R2 from physical damage. Moreover, it looks pretty elegant and gives an easy access to all control elements.

FD1:

HiBy FD1 is shipped in a small white box with shiny silver device outlines and company data imprints. Box is not that thick and holds only 1 layer consisting of soft insert for FD1 and small compartment with the accessories below. Full list of accessories are:

• FD1 DAC&AMP
• soft adhesive insert
• L-shaped USB type-C -> USB type-C cable
• straight short  USB type-C -> USB type-C cable
• long USB type-C -> USB A cable

Logically for the bundle, HiBy FD1 DAC&AMP has similar physical size and even the thickness comparing to R2. It resembles its shape but made of aluminum. One of the design elements is a beautiful recessed imprint of HiBy logo at the facing side.

Moreover, FD1 features its own controls — Play/Pause, Vol UP and DOWN buttons at the left edge, plus the additional USB 2.0 / USB 1.0 slider on the right that changes the connection mode and allows to run FD1 in Windows environment with or without a driver.

There is also a multi color LED that would show the running state and sampling rate of the track. Furthermore, when bundled together, R2 and FD1 LED colors would be synchronized.

Both 3.5mm SE and 2.5mm balanced output are located at the lower edge together with the USB type-C port.

FD1 is also equipped with small silicon standoffs at the bottom to make it less slippery on surface. Wise!

Beans:

Even though R2 and FD1 are more complicated devices, true delight of design admiration comes from IEMs side…

Anyway, the design of the box reminds of R2, has similar matt black appearance with gold outlines and white imprints. When opened — huh, perfect first impression.

Not only BEeans catch a sight with its excellent gold/silver/black color combination but also the case looks very attractive. Perhaps, Beans are the best looking IEMs so far that have gone through my hands.

Full list of accessories:

• BEANS IEMs
• 2-pin, 0.78mm cable
• case
• 3 pairs of memory foam eartips

Beans are made of two aluminum parts — silver body with perpendicular rough notches and top golden glossy cover, all formed to a bullet-like shape.

HiBy / Beans text is present in black color and cute font on both channels, as well as both channels have the corresponding indicators (left and right) represented by the blue and red dots on the transparent acrylic 2-pin cable connector bases. Output nozzles are protected with the aluminum grills.

Stock cable looks pretty good, declared to be OFC, features transparent resin connector housings with polarity indication, aluminum limiter and aluminum housing of the SE plug. Hopefully, HiBy would also include 2.5mm balanced cable version to Beans as an option and as a mandatory accessory when it would be sold with R2 + FD1 as a bundle. It would allow to disclose its full potential.

The case deserves some additional words regarding its design. The material chosen is great — feels like a fabric and looks expensive. The cover is securely held with the help of a magnet. Such case would not only fit IEMs, but also all of the accessories and couple of additional cables if necessary.

HiBy R2 in use:

Of course, R2 is a complete all-in-one DAP, packed with lots of modern features. When sold as a bundle with FD1 — it would only generate more power and allow 2.5mm balanced IEMs to be plugged in. The rest of the features are provided by R2 itself.

R2 uses X1000E CPU which is familiar from the previous experience with Hidizs AP80 family products. HiBy OS and UI are running smooth with no UI freezes or visible glitches. Touch screen is responsive, interaction feels linear and adequate. Screen size is completely enough for the DAP in all applications except such a rudiment function as E-reader which is present here on board. The text in this application is very small that limits its use.

Despite being positioned as entry-level DAP and priced so low, R2 still inherits some outstanding HiBy functions initially presented in their flagship / middle segment models:

• MSEB (MageSound 8ball, equalizer for the true audiophiles)
• HiBy Link (full remote control from a smartphone over Bluetooth)
• UAT (supreme Bluetooth codec, better than LDAC quality)

Besides that, R2also features:

• Bluetooth 5.0
• Bluetooth audio: SBC, AAC, aptX, LDAC, UAT
• Dual band WiFi: 2.4/5.0Ghz
• Paired mic with noise cancelling function
• Dedicated application to record stereo sound (only from inbuilt microphones, no support for external mic)
• Streaming audio: Tidal application (Qobuz should come to R2 a bit later)
• MQA 4x unfold (2x unfold when FD1 is connected)
• USB DAC
• Bluetooth Bi-directional DAC
• HiRes + HiRes Wireless standards approval

Pretty damn full-packed tiny little monster. What other entry-level DAP would feature and offer that much for the price? None…

Let’s get back to the user experience. R2 accepts up to 2TB microSD card and doesn’t have any storage on board. For those who already owned other HiBy players or even DAPs from Hidizs or other vendors that use HiBy OS — most of the UI functions and logics would be very familiar. Home screen consists of the application icons, controlled with slide gestures and has a couple of additional function to quickly go to playing now screen or see wireless connection toggles, time and state. Full application/shortcuts list is as following:

• Music (HiBy Music app)
• Recorder (sound recording)
• Tidal
• Books
• HiBy Link (remote control setup)
• MSEB
• Equalizer
• Import music via WiFi
• Update database
• Wireless settings
• Play settings
• System settings

Settings worth to be mentioned here:

• Import music via WiFi
  • opens the web access to this DAP over WiFi (shows IP address and port) to transfer songs from other devices
• Wireless settings
  • Bluetooth
    • toggles Bluetooth and allows to search and pair with other devices. Also gives the possibility to control which audio codec is used
  • WiFi
    • toggles WiFi and allows to search and connect to WiFi networks. Also gives the possibility to check network state, current IP and setup DNS
  • DLNA
    • just a toggle. Probably should be used to connect to DLNA server or setup DLNA server. Couldn’t find more information yet and hope that this function would be finalized in the nearest updates.

The rest of the settings are self-explanatory, all vital and regular functions are provided.

The only not very user-friendly UI function is a keyboard that pops up when there is a prompt option. Virtual keyboard buttons are very small and sometimes it gets quite hard to press it.

Main application is HiBy Music that handles all types of LQ and HQ audio formats, sorts files by favorites, recent, albums, artists, genres, formats and file names. It also supports playlists and can do the search. Main player screen shows album art, audio format, track time, amount of songs in current list, file properties, lyrics, gives the access to EQ and provides such functions as: seeking through track, adding to favorites, adding to playlist, deleting the file and changing play mode (shuffle, all, repeat 1, repeat all).  Unlike in Android version, audio settings on R2 are called not directly from HiBy Music app but are represented by a separate Audio settings shortcut from one of the main screens.

Audio streaming is provided by Tidal application which requires WiFi internet connection and asks for the login and password right after the initial launch. HiBy has announced adding Qobuz a bit later. My personal preference is Deezer which would probably not appear on this device. Nevertheless, Tidal HIFI account now acts as MQA provider for R2 which can do 4X unfold on its turn. What is peculiar, that even when connected to FD1, R2 would still support MQA unfold but would be limited to 2X only. Still its a good news for the fans who want to have HiRes sandwich and use Tidal or Qobuz applications. BTW, WiFi reception is quite strong and no interference coming in to the sound.

This DAP is able to work in USB DAC mode with either native Windows 10 driver or with the dedicated ASIO driver that would hopefully be released soon by HiBy. One of the drawback of Windows native driver is the maximum of 24bit/48kHz that it can process. Again, hopefully, dedicated ASIO driver would handle all modes in future.

One more strong side of R2 is its battery. Continuous play consisting mostly of the HiRes formats can reach 12-13 hours which is much longer compared to middle and upper class DAPs based on Android OS. Of course, using WiFi, streaming services and Bluetooth would put much more load on the battery. R2 would also get a bit warmer under such circumstances.

Our device is running on 1.0 FW version and there were no FW updates yet for this DAP. There are two option to update: using microSD card or doing OTA update over WiFi.

Anyway, as a summary: even though there are a couple of negative points in R2 user experience (control buttons rattle a bit, couple of functions are not yet fully developed) — it is a strong performer with groundbreaking functionality. UI is fluid, interactions are logic and smooth, battery is long lasting. Plenty of features packed into such a small device.

HiBy FD1 in use:

First of all, FD1 is designed to be used with any source, not only R2 DAP. It perfectly functions when connected to either PC or a smartphone. But concerning its physical shape and software capabilities — R2 seems to be the best pair for this DAC&AMP. We assume that the main idea was to allow R2 users to expand the functionality of their DAPs by adding balanced circuit and squeezing out more power for the end gear…

Since FD1 is not equipped with its own battery — it fully relies on USB power and drains the battery of the source. Ideal situation when you don’t have to worry about the battery level but the drawback is a limited output power. For instance, R2 produces 70mW/channel on its own, while FD1 would produce just a fraction more — 75mW/channel on balanced terminal. SE output is limited to 25mW/channel which is almost similar to any regular smartphone. Despite that, FD1, as a stack component, is able to improve the sound is many aspects which we would review in sound quality section.

FD1 doesn’t get hot during operation and the only sign of life is represented by LED light. Since the shape is similar to R2 — it perfectly fits this DAP underneath and the provided soft adhesive layer does the job in sandwich construction. Unfortunately, HiBy has not provided rubber bands or special plastic case to hold both devices together. Hopefully, they got the point of this complaint and would develop such accessory in future.

On the other hand, HiBy included three types of cables that would make the life easier. L-shaped type-C -> type-C cable perfectly fits sandwich setup, whereas other two straight cables are better to be used for smartphone or PC. All cables have aluminum connector housings and all seems to be durable. This is important because all cables have host and slave side and couldn’t be easily exchanged if lost or damaged.

FD1 is also equipped with its own Play|Pause, Vol UP / DOWN buttons that allows to avoid waking up the screen of a smartphone or DAP.

The situation with the drivers is similar to R2 — native driver support in Windows environment can be expanded to Windows 7/8/10 by switching to USB 1.0 using a special slider button. Although, to be able to play DSD — USB should be set to 2.0 and special driver is required. This driver has not yet been released.

Sound quality: 

Tested with Xiaomi Redmi Note 8Pro, Lenovo Y500, Hidizs Seeds SE and Hidizs Seeds Balanced versions of IEMs.

R2:

HiBy R2 sound makes the impression of a pretty neutral DAP with a slight tendency towards the warmth. Lows, mids and highs, in overall, are in a good balance making this DAP universal for any kind of music genres.

Midbass is powerful, fast and punchy, its expression and dynamics are impressive. Lows are well pronounced, moderately outlined and have a slight touch of lift that adds a bit of warmth and some extra body to the sound.

Clarity and crispness on higher frequencies are moderate, their presence is not overwhelming or irritating. Just enough for a good balance and shows good amount of micro details. Mids are naturally sounding with reach vocals and weighted presence in the entire mix. Female vocals are neither screaming, nor too thin.

Again, R2 signature is a bit on the darker side by very slightly emphasizing lows, no tube-like performance, no cattle effect. Do not forget about MSEB feature that gives the additional control over such aspects of the sound as:

• sound temperature
• bass extension
• bass texture
• note thickness
• vocals
• female overtones
• sibilance LF
• sibilance HF
• impulse response
• air

Channel separation and entire scene are moderate, neither revealing, nor disappointing. Let’s say that it is pretty similar to other entry-level DAPs.

Further sound improvement is achieved when FD1 is connected to R2. And here we have some contradictory feelings. As a matter of fact, we did like SE output of R2 more than when paired to FD1 and its SE output is used. R2 SE output seems to be more detailed, clean (regarding mixing of instruments), highs have better extension and resolution. Sound is more balanced. FD1 SE output makes the sound brighter, puts an accent on highs and sound less intimate and holistic. But this is the case of direct comparison. By itself, FD1 SE output stays significantly better than a regular smartphone or laptop sound in terms of overall dynamics, resolution, instrument separation and power output.

In contrary to FD1 SE output, when Balanced port is used — sound improves in many aspects, leaving R2 behind. First, the signature looses aforemended warmth and becomes a bit brighter but with no further negative effect. Other aspects affected: textures and details get more evident, midbass gets more dynamics and drive, highs are treated better as well — more extended and accurate. Stage also spreads to sides and creates a feeling of larger room.

R2 V/S Hidizs AP80Pro:

For us, the main competitor in terms of audio quality as well as the functionality is the latest Hidizs DAP — AP80Pro. It has quite different philosophy, shows some pros and cons in the direct comparison but stays close to R2 in its nature. R2 is packed with lots of features unavailable for AP80Pro but requires the additional device to manage balanced output. Whereas AP80Pro is not that sophisticated in terms of function list but has balanced circuit on board that is able to drive higher loads due to more output power (190mW/channel).

Concerning the sound — R2 and AP80Pro are pretty close with SE outputs. The slight difference is obvious in the signatures — R2 sounds bit more warm and thick, while AP80Pro doesn’t make any accent on lows. This difference is only fractional, gets evident during A/B tests. The rest of the sound characteristics feel to be similar. AP80Pro Balanced V/S R2 + FD1 Balanced output literally removes the difference even in signatures and the devices get even closer (still AP80Pro balanced output is much more powerful). Therefore, AP80Pro is the main rival indeed, but the decision would be tough since the usage scenarios and philosophy are completely different.

Beans:

Similar to the first positive impression about Beans design, sound quality is most revealing out of three components of this HiBy bundle. Being priced as low as $59 — Beans are the best bullet-like shaped dynamic IEMs so far. Slight and engaging V-tuning serves a good role here, instead of irritating with overly bright highs and overemphasized lows. Everything is smooth, accurate and delightful. Good extensions on both extremes, impressive clarity of highs for single dynamic model, excellent control with clear instrument outlines, more than moderate texturing and resolution.

Beans can easily compete with more expensive dynamic IEMs from Periodic Audio, DUNU, TFZ and other brands. Furthermore, the fit is surprisingly comfortable as for the bullet-like IEMs. Achieved by the combination of weight and stock memory foam tips.

One recommendation: if you like R2 + FD1 + Beans bundle — consider getting 2.5mm balanced cable for Beans. This would significantly improve sound quality resulting from FD1.

Conclusion: 

HiBy released three HiRes components at once, each one represents a great performer, either used as a bundle or separately. R2 is a groundbreaking entry level DAP, packed with lots of modern functions typical for flagship models and delivers audiophile-grade sound quality. FD1 is handy little DAC&AMP that equally improves the sound from a smartphone, PC or even R2 DAP while expanding the functionality by adding balanced output. Beans IEMs make a perfect match to this capable bundle, especially with 2.5mm balanced connection. All three are underpriced judging by the offered features and performance level in comparison to the corresponding rivals. Therefore, this HiRes sandwich or its separate ingredients are all tasty and highly recommended.
