Magaosi K6 — straight to the podium



Going back in time to the point when this blog has just started — the very first IEMs for the review were K3HD and HLSX-808 from Magaosi brand. Thanks to that positive experience, my interest towards writing about IEMs didn’t fade away and grew into long journey with lots of other brands. Now, when another model from Magaosi reached me — it is like going back to those good old times of tube sound 🙂


Anyway, current review model is K6 — way much more technically sophisticated and belongs to the upper price segment. It is based on 6BA units (2 of which are from Knowles and the rest are custom made) with 4 crossovers. Just for the note: there is another «Upgrade version» of K6 available at PenonAudio store which comes with extra Bluetooth wire and pink audio cable. But, technically, K6 and K6 Upgraded are similar. The only difference is that regular K6 have wooden plate under the layer of resin while upgraded version doesn’t have such luxury element.

Packaging, design and materials:


What you cannot blame Asian brands for is their constant attempt to build high quality, attractive packaging. Magaosi K6 comes in a matt black box with extra cover and a window exposing IEMs. Lots of technical information printed on the cover while the box itself has a single element in form of brand name imprint.


Top box cover has folding design and also contains a pocket for user manual on the inner side. Inner box compartment is devided in two parts: top part with soft insert for IEMs and bottom part for accessories.


Box contents:

  • Magaosi K6 IEMs
  • Kimber audio cable
  • 3 pairs of white soft silicone eartips
  • 3 pairs of 2 flange eartips
  • 2 pairs of silicone eartips
  • 3 pairs of foamy eartips
  • carrying case
  • user manual


Eleven pairs of eartips should be totally enough to find the best fit for any ear 🙂 Carrying case is neat but not unique — this design of the case is commonly used by different brands.


K6 IEM shells are made of transparent resin with stabilized wood inserts. The whole structure has unibody injection-molded construction with no compensational openings since BA units don’t require to have such.


The only extra elements are aluminum output nozzles (with aluminum grills) and MMCX connectors. Both elements seem to be inserted during the process of molding — no glue spotted.


In overall, the build quality is perfect while the design is georgeous. Wood panels are beautifully painted with attractive vivid colors, Magaosi brand name golden logo is neatly placed there as well and protected by the layer of resin… Technical structure is also perfectly exposed by the transparent shell material. You can easily count all drivers and even see the marking on Knowles units. Love such IEMs where you can get some extra understanding how it is made in a combination with the exciting look.


Stock cable: first time I see such thick and telling audio cable straight from the box. Seems that it is the best what Magaosi might propose sound and build quality wise.  8-core twisted copper, with aluminum Y-splitter, MMCX connector and 3.5mm jack housings + transparent plastic limiter and transparent silicone braid. Audio jack housing also has the carbon fiber insert. Channel indication is provided by red and transparent plastic rings on MMCX connector housings… But the most impressing is still the thickness of the cable…


By the way, there is another cable by Magaosi which is called «upgrade cable» for K6. I don’t know what else to desire and what else to upgrade… The main difference is that upgraded cable has more cores, seems to be made of silver-plated copper and has some minor differences in the design of furniture. Soundwise, both cables are similarly good. This violet cable comes as a stock one with K6 Upgraded model (together with extra Bluetooth cable).


Magaosi K6 shell design goes to the most comfortable one in terms of fit for all kinds of activities. I call it «pseudo» custom because it reminds of the shells of very expensive IEMs which were aquired after auricle casting process in customer based approach. All of the mass market IEMs from different brands with the same pseudo custom shape had the best fit so far. Under any circumstances. For example: Kinera Idun, HiFiBoy OSV3, Hidizs Mermaid MS1 and MS4. Therefore, you shouldn’t be worried about the fit of K6. The most comfortable and universal shape (for mass market IEMs) along with great choice of eartips and soft but curved earguides should do the trick for anyone. Very tight and secure fit.


Sound quality:

Tested with HiBy R6Pro DAP

Lows and midbass:

Bass side is always different with balanced armature drivers compared to dynamic units. Here is the same: bass is perfectly detailed, well-exposed and plays with lots of textures. But the reach and extension is not as deep as in case of dynamic IEMs in the same price range. It feels more controlled, fast and contoured rather than very deep and emphasized. Lows are always present in the sound picture of K6, moreover — always weighted, apparent and accurate. Although, it would not get that boomy and dimensional even with the most bass-oriented tracks. I would say that perfect performance of bass by a pair of Knolwes BA per channel in Magaosi K6 is suitable for the most of the music genres where the congregated interpretation with excellent layering is a must. Dance music, hip-hop or rap — not as good as soul, rock, orchestra or blues…

Midbass performance is similarly stellar — powerful, rich and tight sound of drums accompanied by the perfect dynamics and articulation. Treble does bring some influence here but not to the extent of making the sound of drums irritating. My favorite test tracks which would sound harsh on drums with some overly bright IEMs didn’t tend to show any inadequacy here.


Mids and vocals:

Although K6 have apparent V-shaped tuning, mids are quite full-bodied and naturally exposed. Main advantage is the mix of good thickness to all voices and instruments together with enormous amount of micro-details BA units are capable of. Resolution is very high, string, bow and wind instruments capture whole lot of attention. Moreover, each sound is perfectly distinguishable in the entire mix. Female vocals don’t seem to be shouting and distructing even with that much of the influence from the lower treble side.



Guess what — yes, the strongest side of high-quality BA units again… Crisp, clear and icy-cold sound of extended treble. Some people might be more susceptible to high frequencies and would vote for less bright presentation… Some (as me) would say that such bright picturing would not let to relax and have a long listening experience. Yes, this is true…, but others would love this sound. What is definitely true is that anyone would be overwhelmed with the clarity and transparency of this range.



Excellent instrument separation + perfect layering of the ranges = quite dimensional soundstage. The only thing that it lacks is the width which would regularly be defined by the extension and volume of lows… which is not perfect in case of most of the pure BA IEMs.


Sound in overall:

Magaosi K6 sound could be described as V-shaped and bright with high resolution throughout the ranges, excellent instrument separation, very good layering, textured lows, well exposed mids and transparent treble. Sound is perceived as being on the brighter side of the tonality, detailed and crisp, with good overall balance and some extra emphasis on treble.

Compared to LZ HIFI A6:


LZ A6 are hybrid IEMs, also based on 6 driver package with extra HF piezo unit and dynamic driver for lows. Plus the ability to tune sound to a great extent by using the stock set of different filters. Altoghether, this make A6 a better and more secure option to consider during such a costly purchase. The only thing that you would not be able to tune in A6 is the fit. Magaosi K6 have much better fit and similarly good sound which reminds of A6 with the least vivid filters (like purple one, for example). Of course, the extension of both ends in K6 would not be as good as dynamic and piezo drivers of LZ A6 would produce but the price is not the same either…

Compared to Hidizs Mermaid MS4:


MS4 is also a hybrid model with Knowles BA units and large dynamic driver for lows. Consequently, lows have more volume and extension but not as textured, fast and detailed as in K6. The rest of the sound characteristics are quite similar. As well as the shape and fit.



Magaosi K6 IEMs go straight to the podium of my personal preferences. Whenever there is a desire to get some juicy, detailed and engaging performance — K6 would be a perefect contender for its combination of great fit and impressive sound quality. Build and design are also nothing more to be desired for the price given, even the cable is the most advanced one that ever came out straight of the box. Therefore, the conclusion is very definite and positive — great option to consider with the ultimate set of all pertaining features, packed in comfortable shape and presented in the attractive package…!
