Hidizs MP145 Pro – we’ve said, they’ve listened

February 23, 2026 ZMarketChangers

The best inspiration for me in writing this article about Hidizs’ new MP145 Pro IEMs is that finally, I can clearly depict facts to support the statement that Hidizs, as a company, listens to its auditory and approaches the new products with the feedback in mind. MP145 Pro is the derivative of the original (og) MP145 magnetic planar IEMs that were and still stay quite rare on the market. The pros of this technology is obvious – agile diaphragm with faster response time, more precision due to even flex driven from both sides and naturally more air pushed with the larger diaphragm area. Such IEMs produce highly resolving, thick sound with outstanding instrument / voice separation.

Original MP145, released back in 2023, are excellent planar IEMs for the price, with just a few complaints mentioned by the owners: slightly prone to hiss/sibilants (skewed towards upper mids) and not that ergonomically perfect for everyone. Both issues were addressed in MP145 Pro. But even more…

This is the comparison of MP145 V/S MP145 PRO specs:

FR curve closer:

Main structural changes:

1T fully symmetrical magnetic circuit (+40% magnetic flux for enhanced clarity, stable magnetic field, and greater driver efficiency)
14.5mm ultra-precision nano-grade planar diaphragm (+30% more copper & wire density for better detail, faster response, and a wider dynamic sound)

Changes in sound:

Sound Signature: transparent, more controlled bass, a reference-grade midrange with reduced coloration, and exceptional treble extension for a more expansive soundstage.

The main changes in sound are the results of the final tuning with more even response distribution in upper mids/treble, slight elevation in bass region and some heavy changes in treble. Whether it is for good or worse – we shall see in the sound comparison section.

What’s in the box:

Hidizs did not disappoint with the bundle contents, as always. Here, in a small but sturdy box you’d find:

IEMs
24 pairs !!!! Carl!!! of silicone ear tips (3 x vocal, 3 x bass, 3 x balanced, 3 x anemone)
3 pairs of sound filters (rose gold – balanced, silver – high freq, red – low freq, 2 pairs in a separate storage case and 1 pair applied to IEMs)
large storage case for IEMs
audio cable
SE 3.5mm plug
balanced Pentaconn 4.4mm plug
some papers

I’ve also got WDC badge along with the bundle which reminds that Hidizs actively collaborates with WDC organization for whale and dolphins preservation program. Learn more about it here:

The first and the most crucial update in MP145 Pro, for me, personally, is the change in audio cable and plugs provided. I’ve been communicating with Hidizs about such option since the release of the og version which I thought lacked the connection versatility out of the box. Such product is an investment that builds joy for their fans for a long period of time and people want to have everything packed together to get the most satisfaction from their purchase. Why would I want to search for third-party balanced or SE cable options if I already made a vote for Hidizs and believe that their equipment worth it… I wanted all components to be provided and tested by Hidizs, and included.

Anyway, I am impressed that Hidizs have listened and now we have the possibility to connect to either SE or balanced source straight out of the box and in the most convenient way. Just detach one plug and connect the other one. Great!

The other notable change is the new shape and overall ergonomics deriving from that. Shape is still very complex, based on whale tale inspiring design with lots of CNC time involved.

Here is some great video of how MP145 Pro are made:

But despite that the weight added a couple of grams, IEMs appear smaller or more rounded. The main change that adds to the ergonomics is the prolongued and thinner sound nozzles that allow for more natural and deeper fit. I would say that MP145 Pro would definitely fit more people.

The only question that I have left is the choice of color for the storage case. I don’t understand why black box with either gold, blue or black IEMs contains turquoise case. The only clue is that it should address the color of the ocean. If so – that’s fine,, there is a logic, at least.

The sound:

I’ve tested MP145 Pro and the og MP145 with Hidizs AP80 PRO MAX DAP (balanced output + balanced ear tips + balanced filters)

First of all, the best part that stay the same for MP145 Pro and it predecessor is the ability to drive those IEMs with low/mid power portable sources. Not a smartphone, of course, but the DAPs with >80mW power like AP80 Pro and above do a great job when set to HIGH gain. Other planar IEMs that I posses are more power-hungry and require >200mW and more to be driven this well. Hidizs gone to low impedance / high sensitivity combination for planars which is an achievement by itself.

Secondly, all the best virtues of the sound of this technology are here: excellent dynamics, layering and intstrument separation, high resolving potential and lots of texturing, especially in mids. Thick mids and overall warm timbre is usually defining and revealing this tech, which is also true for MP145 Pro.

I do like how Hidizs has retuned treble part. It is not that prone to sibilants anymore as it was in og version with low quality recordings and some bright tracks at higher volume. Now, it sounds less aggressive, still maintaining good clarity, presence and extension. Feels more balanced in the sound picture.

Mid bass has the least changes – slappy, fast, dynamic and tight, while the lower bass has been slightly brought forward and the presence is now larger, to my ears. The original MP145 was pretty warm already, due to the elevated bass exposure, but MP145 Pro is another step forward towards bassheads. It is not enormous – just larger than expected for planar IEMs with good control and fast decay. Not smudgy.

So, while the nature/timbre/signature of the MP145 Pro and the og version sound stay close, some obvious changes were made, most notable on refined, less edgy treble and slightly amplified bass. My verdict is that those changes are for good, since IEMs sound wider and smoother in overall, exposing planar advantages and keeping the rest of the prime characteristics untouched.

I also like the synergy of AP80 PRO MAX & MP145 PRO pair. Having more powerful balanced output with 4.4mm plug allows AP80 PRO MAX to reveal planar IEMs potential sonically, with more robust and secure physical connection between the two. Along with more drivability, balanced port also eliminates more noise on the background, slightly widens stereo panorama and separates channels better. The amount of output power is enough even at SE 3.5mm plug, but feels like there is more room ahead on balanced output that positively affects the dynamic range in overall.

Conclusion:

My collection of planar magnetic IEMs grows. While the choice is still quite limited, rare products that are available shape this segment and deliver impressive results. It is obvious that Hidizs is concerning this technology as the cutting edge and investing its time and efforts to bring each single products in this niche close to the entire excellence. This is a flagship model with all positive outcomes of such treatment. Furthermore, this is the 2nd gen release, all rough edges indicated by the auditory are now polished. With MP145 Pro release Hidizs literally declares that feedback matters and that their community response shapes the future. As to the product itself – MP145 Pro IEMs have matured technically, ergonomically, in connectivity and, what is the most important, in its refined, more delicate sound.

MP145 Pro are planned to be released at Kickstarter on March 5th, 2026, 10:30AM EST. Prices are planned as follows:
