RATING B

Go ahead, the final note it's because on that price competition that exists today in the planar market, and the tuning selected for the MP145 perhaps the biggest handicap of this headset. It had everything to succeed, a groundbreaking design, a driver that at times invades you and transmits sensations that are difficult to achieve in this price segment.

Although it's a headphone designed and thought for enjoyment, even for a lover of electronic music, they are a better choice than the LETSHOUER S12, which is saying something. Problem is that the relaxed character in the upper zone weighs too much on some recordings. Add to that a booming character in the lower zone, and you end up with all the technical-loving audiophiles off your list of potential buyers. The HIDIZS MS3 was a much more aggressive tuning in that aspect, with a more defined and shorter bass; Of course with much more load at high frequencies.

The more headphones I review, the more I realize the tonal preferences and how personal they are... this headphone reminds me a lot of the FiiO FH7S and the ARTII R1 and they are much closer to my preferences than more HARMANIZED headphones. On some tracks, because of the imaging on, I could even compare to the LETSHOUER 07jm, for its warmth presentation without being excessively intimate.

At the end this is about where to put your money, and sadly I can't recommend them. Apart from the sound reasons that can turn away all those who are not looking for warm tones, it has 2 other problems: The fit is horrendous, wide and short, almost impossible to stick it to the shell of the ear (which would probably would give even better performance) and it is exhausting to have it on for hours; And then comes the issue of packaging, for €150 this cable and the box do not seem to me to be up to par, I can think of several headphones that make better use of our money.



A shame, HIDIZS, really, you had an incredible driver here, perhaps the following review will be the definitive one. I loved the HIDIZS MS3, and this planar its on the right track, but both the extension of the bass and the adjustment of the headphone itself need to be improved.

Strong bass, good Sub-bass performance
Presentation and natural image
Excellent construction, fragile paint
Voices and instruments sink into the scene easily
Some resolution is missing
Below price packaging. The cable is 3.5 mm.
Huge capsule, horrendous fit

An iem that works wonderfully with metal and rock, where those electric guitars can be a bit grating with bright iems. I had never enjoyed L.A. Woman by Doors or The Number of the Beast by Iron Maiden as much as I did with these.

Thanks to Hidizs and gadgetgod for the review tour of the MP145.I know this is quite late in coming, but here it is.

As always, the reviews are all mine, and am not compensated in any way by either cash or kind.

The MP145 is a special iem in that 1% of every MP145 order goes directly to supporting Whale and Dolphin Conservation (WDC).

Build

The MP145 is a fairly large iem with a full metal body with an interesting faceplate. The plate's grooves represents a whale's tail, in effect representing the Whale and Dolphin Conservation effort.

The Tin P1, in the picture is dwarfed by the iems. The MP145, still weighs in as much as the Tin P1! The nozzles are fairly large and I was able to find a fit with the Penon Liquer tips.

I have small ear canals and dont prefer large nozzles due to comfort issues. However, with the Liquer tips, the iems sat comfortably in the ears.

The stock cable is a nice braided litz cable and sport a 14.5mm planar driver to do the sound duties. The iems also come with replaceable nozzle filters, which I did play with during the review.

Sound impressions

For the review I used a Lotoo Paw S1 in High gain mode and was able to drive the iems well at 50 volume.

The filters dont seem to change the sound by much, from my A/B ing, and will continue the rest of the review with the Gold filters, for the sake of convenience.

Tuning

The MP145 is tuned against the Harman 2024 target and this shows very clearly, with a sort of pleasing V shaped signature with slightly boosted bass and treble.
The tuning is very reminiscent of the Tangzu Zetian Wu in terms of tonality and resolution.

Imaging is excellent with fast decays and excellent instrument placement. There is some mid thickness that borders on fuzziness in the vocals. Could be the tips or source, I am not sure.
There is a very little bit of treble sizzle on high hats that works for a lot of tracks, but could get fatiguing on poor recordings and bright tracks.

Bass is quick and thick, but not the same quality as a DD, but again not as short a decay with other planar iems. There is a little more sustain, adding to weight of percussion tracks.
The sustain almost has a little bit of influence on the lower mids, lending a little bit of weight to the mids.

Mids are quite decently done, but a tad bit recessed, especially male vocals. Female vocals benefit a bit more than the male vocals. A lot of the nuances are translated especially with female vocals.

Stage is wide, but quite 2D.

I did briefly watch the Joker: Folie à Deux trailer with the iems, and boy they sound good. Looks like a special usecase in addition to music with the iems.

Conclusions

While the review is fairly short, this summarizes the MP145 in a very crowded mid-budget market of excellent iems. The MP145 does hold out on its own and is a choice that could outlive other planars in its price range, eg, Tangzu Zetian Wu and the Hook X.

This is post the kickstarter and marketing controversies, therefore with an undiluted view of the iem with its competition

Unboxing and Quick Summary







Packaging

• Hidizs MP145 with rose gold nozzle attached to it
• Soft carrying pouch
• Wide selection of ear tips.
  • 3 pairs of balanced, generic silicone ear tips (S, M, L)
  • 3 pairs of bass, generic silicone ear tips (S, M, L)
  • 3 pairs of vocal, generic silicone ear tips (S, M, L)
• 6N Silver-Plated Single-Crystal Copper Wire
  • Build quality is ... fine. Not good but not bad, feels a bit on the cheaper side
  • Ear hook's shape are really weird for my ears, so they do strain and make my ears a little pain after longer listening sessions.
• A small case containing nozzles
  • 1 pair of silver nozzle
  • 1 pair of red nozzle

Build Quality

• Build quality is very good, shell is made entirely out of metal.
• Very sturdy but is very heavy.

Fit

• Nozzle is HUGE in terms of width, while being slightly longer than average.
• Fits is excellent. Very lightweight and the shell is super comfortable.

Tonality

• Mild V-shaped

Tuning Nozzles

• Rose Gold
  • Balanced mild V-shaped signature.
  • Most balanced out of the 3 nozzles to my ears, nice mix of clarity and warmth.
  • This will be my go to pick, and will be used throughout this review.
• Silver
  • Bright tilted mild V-shaped signature.
  • Adds a little more sparkle and air, providing extra clarity and brightness, but also becomes a bit more metallic and thin at the same time.
• Red
  • Warm tilted mild V-shaped signature.
  • Favors male vocals, but will mask some clarity especially for female vocals, and boominess will be even more apparent.

Bass

• Bass is quite balanced between sub bass and mid bass, with a slight emphasis on the mid bass.
• Rumble and slams well, with decent definition & texture and good speed & decay to it.
• However, the bass lacks a bit of tightness, sounding a little boomy.
• Overall, the bass performance is quite decent and satisfying for a planar, but the combination of boominess and quick decay of the bass makes it sounds a little weird.
• Quantity is slightly on the bassy side, but not quite basshead level yet.

Midrange

• Low midrange comes with some warmth, giving male vocals and instruments a nice weight and body without being muddy or bloated.
• Upper midrange is very smooth and has just enough energy for vocals to pop out from the mix without being shouty at all to my ears.
• Note weight is on the slightly thinner side due to the elevated treble response.
• Timbre is surprisingly natural for a planar IEM, which isn't as metallic as other planar IEMs such as the S12, but there is still a small hint of planar sheen.
• Overall, the midrange is very well done in my opinion, especially for a planar IEM.

Treble

• Treble has plenty of sparkle and airy, yet it remains quite smooth.
• Treble extension is very good, giving a great sense of air to it.
• However, there is a audible peak at the mid to high treble region, which does adds some harshness and sibilance to vocals.
• Details in the treble can be perceived easily due to how sparkly, smooth and extended the treble is.

Technicalities

Resolution

• Resolution and detail retrieval is great, on par with other planar IEMs that I have tried.

Soundstage

• Soundstage is on the wider side and is quite spacious, with a decent depth to it.

Imaging

• Imaging is quite accurate, as I am able to pick up direction of sounds with good accuracy.

Separation

• Separation and layering is good, no issues with congestion on busy tracks other than the bass and midrange transition.

Comparison
Hidizs MP145 vs TANGZU x HBB Wu Heyday Edition

• Accessories:
  • I can't compare this element as I only borrowed the Heyday from one of my good friends.
• Fit and Comfort:
  • Heyday is a lot more comfortable to my ears, as the MP145 is just too bulky and big.

• Bass:
  • Heyday is significantly tighter with a bit more punch but less slam compared to MP145

• Midrange:
  • Lower midrange on the Heyday is cleaner than the MP145, with a slightly more emphasis on the upper midrange.
    • Female vocals will be the star of the show on Heyday instead of male vocals, as they sound thinner and less natural.
    • However, while female vocals isn't as good on the MP145, it has a much more balanced midrange, where both vocals are pretty decent
• Treble:
  • Different story from what the graph tells, the Heyday is actually a bit smoother to my ears, probably because of the better fit and deeper insertion, which I could not achieve with the MP145.

• Technicalities:
  • Both have similar technicalities and they trade some blows but not by a large margin.
  • The MP145 has a slightly larger stage while the Heyday has a slightly cleaner separation.
• Overall, I enjoy the Heyday a lot more due to fit and comfort, and the overall sonic performance fits a little bit better to my preference.

Conclusion

• Overall, the MP145 is one of the better sounding planar IEMs that I have tried in the price, but I can also see that the fit and comfort of the MP145 can be a huge problem for many people, considering that I already have larger ears than most of my friends.

• Is it going to dethrone the Heyday to be the king of planar IEMs under $200? I don't think so.
  • The Heyday pretty much still remains my favorite planar IEM for under $200
  • However, the MP145 can compete directly with the Heyday in terms of sound, with some trade offs such as comfort.

Thanks for reading!

Being in this hobby has been full of ups and downs. I have seen planars like oBravo Cupids which were highly divisive at the time at their launch and I still have them in my collection. Then came the classic TinHifi P1, something that people still look for in the Pre-Loved sections. I have been lucky enough to have used mostly all of the Planars that i could have managed to get my hands on . Off-late, the S12 has been my favorite. However MP145 is here to lay stake to the top tier Planars that i have used and that is what i am going to explain in this review.

Before we go any further, the MP145 has been forwarded to me by Hidizs as a part of the India tour. The thoughts, however, are my own and are not, by any chance, influenced.

Build Quality:
Constructed with premium materials, the MP145 exudes durability and reliability. Its robust build ensures longevity, making it a worthy investment for audiophiles seeking long-term satisfaction.



Comfort:
Thanks to its ergonomic design, the MP145 offers a comfortable fit for prolonged usage. The included selection of ear tips ensures a personalized fit for every listener, enhancing both comfort and sound isolation.

Sound Signature
The MP145 boasts a balanced sound signature that caters to audiophiles seeking clarity, detail, and depth in their music. Let's delve into its performance across the highs, mids, and lows:

Highs:
The high frequencies on the MP145 are nothing short of mesmerizing. With its extended treble response and exceptional clarity, every shimmering cymbal crash and delicate string pluck is rendered with precision and finesse. There's a sense of airiness and openness in the highs that adds a layer of excitement to any track without ever veering into harshness or sibilance. The White filter is the one if you are a treble-freak.

Mids:
The midrange on the MP145 is where its true magic unfolds. Vocals are presented with a lifelike presence, conveying emotion and nuance with astonishing realism. Instruments come alive with clarity and texture, allowing listeners to discern every subtle detail in the music. Whether it's the warm timbre of a guitar or the rich resonance of a piano, the MP145 reproduces midrange frequencies with captivating authenticity. It also goes without saying that it hughe;y depends on the source as well. The rose gold filter is the way to go for Mids.

Lows:
In the realm of bass, the MP145 strikes a perfect balance between impact and control. The lows are deep, powerful, and well-defined, providing a solid foundation for any genre of music. From the thumping kick drums of electronic dance tracks to the resonant basslines of jazz and hip-hop, the MP145 delivers bass with authority and precision, never overpowering or muddy. The red filter offers you more bass slams but then mids also gets recessed so if you love mids, go for the Rose Gold Filter.



Included Filters:
One of the standout features of the MP145 is its customizable sound tuning system, which includes three interchangeable filters: Bass Boost, Reference, and Treble Boost. Each filter offers a unique sonic profile, allowing users to tailor the sound signature to their preferences: My Favorite is the RoseGold(Balanced) Filter

Bass Boost(Red): This filter enhances the low frequencies, providing a more pronounced bass response for those who crave extra impact and warmth in their music.
Balanced(Rose Gold): The reference filter maintains a neutral, balanced sound signature, faithfully reproducing the artist's intended sound without any coloration or alteration.
Treble Boost(White): The treble boost filter accentuates the high frequencies, adding sparkle and brilliance to the sound while maintaining clarity and detail.

With these interchangeable filters, users can effortlessly customize their listening experience to suit different genres, moods, and preferences, making the MP145 a versatile companion for every musical journey.

Conclusion:
In conclusion, the Hidizs MP145 IEM is a true masterpiece of audio engineering. With its balanced sound signature, customizable filters, and premium build quality, it sets a new standard for portable audio excellence. Whether you're a discerning audiophile or a casual music lover, the MP145 promises an immersive and captivating listening experience that will leave you spellbound.

Planar IEMs have always attracted me with their speed and dynamics. Over the past few years, I have been following the rise and development of Planar driver-based IEMs. The journey for me started with the Tin HiFi P1 Plus, 7Hz Timeless, LETSHUOER S12, KZ PR2, etc. Earlier back in the day, Planar Magnetic Driver-based IEMs used to be quite power hungry like the Tin HiFi P1 and P2 IEMs were used to be tested on desktop amplifiers. And they had that amazing sense of scalability as well. But as time passed, the technology evolved and we got some new IEMs that don’t exactly require such absurd amounts of power. I am talking about the LETSHUOER S12, 7Hz Timeless AE, etc. This generation of Planar Magnetic Driver IEMs obviously benefits from good quality DAC/AMP or Dedicated DAP, but they never showed me such high requirements. Okay a lot of blabbering about the recent history and development of Planar Magnetic driver for IEMs in the recent times, now let’s get to talk about the product at hand today. Today I am going to share my review of this brand-new planar IEM, the Hidizs MP145. Hidizs MP145 packs a 14.5mm massive planar magnetic driver unit on each side with large-sized metallic shells. At the time of this write-up, the pair retails for about 150$ available across different retailers worldwide. I have spent a decent amount of time with the set(like 4-5 weeks now), with multiple sources and music genres, let’s start with the review today.

A Short Disclaimer:-

Hidizs MP145 was sent to me by Hidizs as a part of a review tour in India. Rest assured, all impressions here are my own based on my own experience with the pair for the past few weeks. It has been in my daily rotation for quite sometime now. My opinions might be biased based on my own personal preference for listening(which is mostly neutral with some sub-bass boost).

Design and Build Quality:-

The ear shells of MP145 are built like a tank. They are metallic shells with a mechanical cyberpunk style look with a large, and by large I mean really large. The shells are massive, to be honest, and at first, I was kind of sceptical about whether they would even fit me or not. Surprisingly, despite their massive size, they fit me perfectly. They sit a little on the outer side of my ears, but they sit comfortably and never fall off my ears. The shells have a rich, matte finish, they look and feel premium. Great job with the craftsmanship I would say. The one that I have has this gunmetal titanium colour, which looks minimalistic and with the matte finish has a charming appeal, atleast for me.

Hidizs MP145 has replaceable ear nozzles. There are three sets of nozzles with the MP145, Rose gold, Silver, and Red. Each set has a different nozzle filter density that brings noticeable changes into the output with the pair. Which I will discuss further after the sound quality part.

Fit & Isolation:-

As I mentioned above, the pair is a bit big in terms of size, but I have no issues at all with fit. The pair fits me like a charm(I have medium ears, and I usually don’t get any fit issues with the IEMs. I would say the big size of the shells might give fit issues to people with small ears. I have no issues in isolation, using Softears UltraClear eartips for myself and I have no issues.

Driveability:-

For the past few weeks, I have been using the Hidizs MP145 as my driver. I am taking it to the gym, I am listening to it on my bed, and I am just using it on a regular basis. Yeah it has seen a few breaks every now and then, but then again it has found its place in my regular cycle. For my usage, I have used it with Questyle CMA18P and iBasso DX260 with a 4.4mm terminated cable. It has never shown me any issues in terms of driveability although I would say I had to increase the volume a bit extra as compared to other IEMs that I have(Softears Twilight/Thieaudio Hype10, etc.). I won’t call the Hidizs MP145 to be demanding or a power-hogging set, yet it benefits from better sources, so I suggest you guys give it the best you have and you will have a good time I assure you.

In simple words, Hidizs MP145 will sound good with your standard DAC/AMPs(tested with AFUL Snowynight/Hidizs S9 Pro Plus), It never lacked any performance for me, but when I paired it with CMA18P and DX260, the experience was on a different level. So, just treat the MP145 with your best, to experience the best sound.

Sound Impressions:-

Hidizs MP145 has a very lively and immersive sound presentation. The sound has a neutral to slightly warm tone, the instrument notes are well-defined and precise. There is no audible sibilance or harshness even on louder volume levels. I appreciate how controlled the MP145 resolution is. It is crisp, it is accurate and has amazing clarity. The pair maintains absolutely amazing clarity throughout the frequency band. Overall tuning profile is very balanced with no particular frequency being emphasised.

Lower-end packs some solid bass response. The sub-bass is rumbling and the mid-bass hits fast and quick. The lower-end region is tight and precise, there is no bleed into the other frequencies. Bass is fast, I would say it could use a bit more prominence in the mid-bass to add more slam and body but I think that might affect the speed and snappiness of the lower end. Midrange sounds clear with an absolutely lovely vocal presence. While writing this review I am listening to Nandini Srikar, an Indian artist who has such a beautiful vocal presentation in Bhare Naina track from Ra One, a Bollywood movie. The vocals are nicely textured and showcase delicate details quite beautifully on the MP145. Lower Mids feel slightly recessed to me, which gives a wide and open feel to the overall soundstage. The treble is crisp, detailed, and well-extended. It isn’t super detailed in treble, but smooth and well-rounded I would say. Another thing that I love about Hidizs MP145’s sound is its liveliness and energy in the treble. The pair showcases the perfect balance here, it never got overwhelming or tiring for me, I am simply delighted to have experienced such an amazing sound with the Hidizs MP145. This makes it one of my favourite IEMs in recent times.

Instrument notes are very well-defined and one can expect amazing layering and imaging capabilities with the Hidizs MP145. The pair showcases absolute excellence in those technical aspects. The soundstage is brilliant, just like the size of the ear shells, the soundstage presence of Hidizs MP145 is massive. It is deep, airy, and wide, giving a massive feeling whenever I listen to the set.

Now on to some cons for the Hidizs MP145. As I said earlier, I would have loved a bit more slam and body to the mid-bass on the Hidizs MP145. Secondly, the stage feels massive, width and depth are simply outstandingly big on the pair, but I personally feel like the height of the stage could be a bit better it forms a 3D immersive, and big soundstage, just a tad bit more height would have made it the perfect choice for me. Believe me, these two are very minor cons and you can also call them nitpicking haha, man every time I listen to the MP145 I wonder how can an IEM sound so massive and fast at the same time, well that’s the magic of Planar and Big shell I believe.

Next up, Hidizs MP145 comes with a bunch of nozzle filters, they are said to have tuning changes. The above impressions are with the Rose Gold color filter, but we also have Red and Silver filters. So let’s see what changes they have in terms of sound quality.

Red Filter:-

With the Red filter, the sound of the MP145 becomes a V-shape signature, the bass gets a bit more slam(the thing I had missing on the Rosegold filters). Although the output gets a little intimate compared to the Rosegold filters. Treble also gets a little leaner with the Red Filter. I would say details are also slightly better on the Rosegold filter. But the increase in bass presence makes the output a bit warmer feel.

Silver Filter:-

The silver filter is probably the treble-enhancing one, i feel the treble gets a bit forward, but a bit of leanness i could notice there. Bass is also feeling a bit lean in this filter or is this the result of using on Red filter for the past two hours lol. But yeah, my favourite filter with the MP145 is the Rosegold one as that offers the perfect balance for me.

Some Comparison Time:-

As of writing this review, I have experienced a bunch of Planar IEMs including the NiceHCK F1 Pro recently, So today’s comparison will be with the F1 Pro.

NiceHCK F1 Pro vs Hidizs MP145:-

>Fit wise the F1 Pro is very comfortable, MP145 has bigger shells.

>MP145 has a more detailed and more neutral sound presentation.

>F1 Pro has a warmer tone in comparison(although it is also fairly neutral).

>F1 Pro has one of the smoothest trebles in Planars I have experienced so far, MP145 has that smoothness but also has more energy and sounds more resolving as well.

>Stage of MP145 is massive, F1 Pro has a intimate presentation.

>MP145 Bass is snappier and has faster notes as well.

>MP145 has more resolution.

>Vocal texture MP145 is simply next level.

I love F1 Pro, it is the safest tuned Planar IEM imo, but MP145 takes things on next level. Be it the clarity, be it the overall presentation, MP145 is on the another level.

Final Words:-

I place Hidizs MP145 highly in my top planars. Over the years I have experienced a lot of different planars including the Tin HiFi P1 series, and P2 as well but I consider that as an HP as it takes desktop level amp lol, then the KZ PR series, The LETSHUOER S series, and believe me, the MP145 is among the top three from my side. The other two? Well, they are something special and I would mention them as well(LETSHUOER S15, and CFA SuperMoon), but both of them are way above in price league compared to the MP145. For me, Hidizs MP145 offers great value for money with excellent sonic performance, and a uniquely shaped massive-sized shells. Well, that’s about the Hidizs MP145 from my side, I hope you guys enjoyed reading this review of mine, I would like it if you guys could leave me a like here For any questions, you can ask me in the comments section below.

Prelude:
The war of planar IEMs has brought us a heavy harvest of many very interesting in-ear headphones models. I remember when Tin hifi presented the P1 model and started a small revolution on the market. Although I liked the P1 very much, it still had a few limitations, one of which was the difficulty in driving and a really huge appetite for power. Then, many manufacturers entered the fray and also wanted to have their share in this market segment. So far, my planar IEM collection includes models such as: TIN P1, P1MAX, Letshuoer s12pro and s15. However, I have heard a lot about the unique project from the Hidizs brand. I am glad that I have the opportunity to supplement my collection with their innovative project, the MP145. You will find out what its innovation is later in my review. Let me just mention that the MP145 is a model based on a large 14.5mm planar transducer and was priced at USD 159. Of which 1% of this price goes to help save whales, which I personally think is a very good and noble initiative.


Unboxing and ergonomics:
Well hidizs has packaged the MP145 in a very thoughtful way. We have a paper box with product information and a good-quality hard box made of thick plastic. It can successfully serve as a larger organizer. Inside, apart from the headphones themselves, there are three sets of tips (vocal, balanced and bass) in sizes S, M and L and it must be admitted that they really influence the sound as described. Then we have three types of filters in the form of screw-on caps (treble, balanced, bass) and these filters also strongly influence what we hear. The set also includes a high-quality SPC cable in the 4.4 or 3.5 mm standard and an ecological leather bag for storing the headphones. As for the cable, it is of really good quality and sounds quite good. The tips are also of very good quality, so the set is complete and does not require replacement of accessories. Unfortunately, the headphones themselves are not the smallest and weigh quite a lot. Personally, it didn’t bother me, but people with small ears or sensitive to the weight of the headphones should take this into account. Behind the weight, however, there is a solid aluminum body that provides a truly armored casing.

Sound:
A lot depends on the configuration we choose. Therefore, I will try to discuss several variants. For my tests I used earmen angel and fiio k11.




Bass: Low tuning depends on the selected tips and filters. On the factory balanced filter, when selecting balanced tips, the bass is embedded in the background. It is not overbearing and is more audible than tangible. However, we can quickly change it by selecting a red filter with bass tips, then the whole thing changes by 180 degrees. On red tips, the sound becomes less transparent, but we gain a solid and tangible bass foundation. Overall, thanks to the use of a planar transducer, the bass is fast and well-produced. Its quality is really great considering the price of the headphones.

Midrange: The midtones are generally slightly recessed because it is a harman tuning. However, the vocals are always clean and clear. We can get a U-shaped sound or bring voices closer to us using vocal tips. The amount of instruments and information is always large. The stage itself also impresses with very good depth, the width of the stage is slightly smaller, but we do not feel claustrophobic, because the instruments are very well distributed in space. The MP145 are not technically tuned, they are rather pleasant headphones for relaxing and quiet listening.

Treble: We can adjust the high tones to our needs. By choosing red filters, we will have more bass and midrange, and the treble will become calmer and less present. However, by choosing silver filters, we will get great extension of high tones and even more details and information. The technical layer will improve, without artificially raising the mountain or pushing it out excessively. You can hear the many benefits of the planar transducer here, at the same time, thanks to excellent tuning, hidizs cleverly got rid of the metallic and unnatural timbre, tuning the planar transducer to resemble the warmth of a dynamic transducer as much as possible.

Power appetite:
Hidizs MP145 are not particularly demanding in terms of current, but they gain a lot from a more powerful source and it is worth giving them more power.


Comparisons:
Hiidizs MP145(159USD) VS TIN P1(169USD)
Tin P1 are already a few years old, but they still stand out on the IEM market. First of all, with a beautiful neutral sound. However, the MP145 are much more musical headphones, less linear, but also with more bass, which can often be missing in the p1. P1s are also much more difficult to control and therefore less mobile. The MP145s offer a larger stage, but the P1s have more treble. Generally speaking, the MP145 is full of great progress in planar IEM technology that has recently taken place.




Hiidizs MP145 (159USD) VS TIN P1 MAX (120USD)
Tin P1max is a new improved version of the p1 model and honestly I love this model because of its beautiful full sound. P1max are also tuned for entertainment and have a good amount of sub-bass. MP145, however, have a larger stage and more tuning possibilities. Overall, considering the number of possible configurations of the MP145, they are more versatile. P1max are still great little headphones, but the hidizs MP145 are a kind of development of their sound at an even higher level.

Hiidizs MP145 (159USD) VS Letshuoer s12pro (139USD)
S12Pro is a truly legendary model. In technical terms, s12pro focuses more on the technical layer and less on entertainment. Of course, the s12pro sound great, but the MP145 are more warm, they are tuned typically for entertainment, so we have more fun with them. However, s12pro may be better if we are looking for a very technical sound. Both pairs of headphones are great, but their tuning is completely different. Therefore, in this case, everything depends on our preferences and preferences.

Hiidizs MP145 (159USD) VS Letshuoer s15 (329USD)
Letshuoer s15 is the undisputed leader of planar headphones. This is also reflected in the relatively high price. In terms of sound, the S15 are smoother, slightly more resolving headphones with a higher technical layer. However, their price is also much higher than the price of MP145. The MP145s sound equally great, presenting a high level of sound and plenty of detail for their price.


Summary:
The Hiidizs MP145 are excellent headphones and have been priced very well indeed. Importantly, we can change a lot in them and adapt them to our needs. The filter system and excellent tips allow you to have a lot of fun with the sound. The MP145 tuning itself is rather entertaining and focused on listening pleasure. However, the resolution and separation are very good. The quality of workmanship is exemplary. The only downside may be the large size and weight of the headphones. Overall, the MP145 are very good headphones offering excellent sound quality and a very high level, so they will definitely stay with me for a long time and have my full recommendation.

Introduction!
Hello friends!
Today in our review we will look at a new planar product from Hidizs.
The headphones come in a fairly small box with a nice design and a picture of the headphones on the front, and there is also the Hidizs brand logo, the name of this model MP145 and the hi-res audio logo here in the corner.

Well, here, as always, the technical characteristics are indicated and a planar driver with a diameter of 14.5 mm is responsible for the sound, and the sensitivity is 104dB, and they received a 30ohm impedance, the headphones are not very hard for driving.

Let's take a look at what's included!

And first of all, we are greeted here by headphones made entirely of metal in a dark blue color in my case, and in my opinion they look quite unusual and good in their own way, the front panel here has a design that imitates the tail of a whale and there are two side holes for compensation.

And another one is located on the inside of the case where you can see the markings of the right and left channels and the inscription Hidizs mp145, and of course the connector here is standard, it’s 2pins and it goes exactly flush with the case, which is a plus for me!

But the nozzle here is quite wide and has the ability to install various filters from the kit; we will look at them a little later, but with the fit, everything is fine here, despite the considerable size of the headphones themselves, they sit in the ears very tightly and there are no problems with sound insulation.
Accessories!
In terms of accessories, in my opinion, everything is generally super, there is this black case made under leather, inside of which there is an excellent, lightweight, especially tangle-free cable with 2-pin connectors and a balanced 4.4-pin plug, as I chose when ordering!

And there is also this set of replaceable filters: silver for those who like a brighter setting, red for those who like a very neutral presentation of mid frequencies, and copper for those who like a more balanced sound, I used it when listening to headphones.

Well, that’s not all, friends, probably we should give special respect to such a good organizer with a bunch of ear pads for every taste and color.

How do these headphones sound?
Now let's talk about the sound and look at the graph of these headphones in comparison with the Letshuoer S15 and I will probably be the only one who compared them together, and in general their frequency response is very similar, that is, at low frequencies and at high frequencies, but in the upper middle The S15 will definitely be smaller, this can be heard by ear when comparing these headphones, but in any case, both models are very close to my target, which makes me happy.

Low Frequencies:
I’ll start, as always, with an analysis of low frequencies, and since this is a planar driver, the bass in these headphones slaps and hits just as it should, this is the most concentrated and accurate very textured blow with a soft smooth attenuation, and with transparency and texture reproduction, everything is generally excellent here!
Mid Frequencies:
But what also pleased me was how they did a very good job of revealing the middle d
range, the MP145 simply feels some kind of crazy airiness and transparency with an excellent and maximally developed legible space in which the instruments are not lost at all, and the analytics in this area surprise every time I listen and I can easily divide literally the entire composition into separate layers be it a heavy metal track or something lighter and calmer, such as some kind of ambient.
And the vocal part here has excellent weight and is very clearly brought forward along with the percussion drum part, and I think this voice production is already familiar to many and there will definitely be its connoisseurs, since the vocals here are revealed to be very well articulated and very emphasized in timbre, and the drums have the most accurate emphasized transients and leave behind very long trails of reverberation, in my opinion, the presentation of this area is excellently revealed precisely from the technical and at the same time very immersive pleasant musical side, although this area is presented a little more energetically and fervently than in s15.
High Frequencies:
The high frequencies are just a godsend, here you have an excellent long expansion, but already with slightly more extended and accented detail on the plates than in the S15, and tonally this area feels colder and I would even say monitor with very good percussion playback clarity, various clicks, calls and micro-details and the resolution in this range and the study of the plates themselves and their plumes is at a very high level,and the presentation itself may not be as neutral and warm as in s15, but for me it is still very pleasant, not tiring, and without any obvious hints of sibilance, planar rustling or pretentious fake resolution, that is, to summarize, everything here sounds very harmonious and at the same time, only positive emotions remain after especially long listening sessions.
Yes, and in terms of genres, as for me, there are no restrictions here, these are very technical and analytical headphones, so they are perfect for heavy, high-speed genres that require quick hitting, but something easier, of course, they reproduce without any problems at all, the only thing you should understand is that due to this, the headphones are quite demanding on the quality of recording material.
Stage and stereo panorama:
And of course, the sound stage is also in complete order here, and these headphones really reminded me of my open full-size headphones Zeus Elite, there is a very good well-developed width here, and the depth of immersion is at an excellent level, as is the drawing of individual plans and images.
My conclusion on this headphones:
Hidizs Mp145 turned out to be excellent planar headphones with a very technical and mature sound presentation and are ideal for all musical genres, as well as for everyone who often asks questions in the comments like which headphones to choose to get a noticeable increase in sound quality, I can definitely recommend.
These are planar headphones because in my opinion they play too well for this price and to then go a few notches higher you will have to pay two or even three times as much, so in this price range it will definitely be be a great choice.

I will be glad if you subscribe to my YouTube channel and watch this full review on Hidizs Mp145!

Hidizs has consistently delivered impressive sound in their DAP and DAC/AMP products (since the first AP60, my first entry DAP), but not every IEM from Hidizs that I impressed. Before trying the MP145, I've experienced Hidizs' MS1 Rainbows (loved), MS2 (decent), and MM2 (mediocre). The MP145 caught my eye, and thanks to an opportunity from Hidizs, I now have the chance to review it. As a first-time Head-fi reviewer, I'll do my best.

Disclaimer:
I am not a professional reviewer but a passionate audio gadget enthusiast. This Hidizs MP145 unit was provided by Hidizs for review, and I will offer an honest and sincere review based on my listening experience.



Let’s start from the technical specification of MP145 (I copied from Hidizs.net)

- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification

As “145” in their model name is from 14.5mm planar magnetic driver, which is typical size that you can find in many planar driver IEMs in the market. If I haven’t heard anything about the hype of this guy, I would just skip due to tiredness from planar war that happened recently. But now this unit is in my hand. So, let get started.

What’s in the box:

• Hidizs MP145 IEMs main units
• 6N SPC Cables (I choose for 4.4mm balanced cable)
• 3 pairs of Vocal ear tips as S, M, L size
• 3 pairs of Balanced ear tips as S, M, L size
• 3 pairs of Bass ear tips as S, M, L size
• Storage pouch
• A box with 2 pairs of nozzles filter as Red for bass, Silver for treble, with pink attached with IEMs out of the box as balance filter.

Let’s talk about the accessory that MP145 comes with. I found that none of the provided ear tips can match my preference because the stem of provided ear tips are too short for me to match up with bulky size of housing unit. So I stick myself with Spinfit W1. The provided cable is quite nice looking, soft, with perfectly matched sound together with MP145 IEMs unit made them unnecessary to re-cable. The pouch looks quite nice but flimsy, very thin and not so spacious like it could not protect earphones from anything. I would prefer hard pouch like the one that came with Hidizs MM2 or a plasticky but sturdy like the one that came with Gizaudio Chopin also better for me than this one.




One of the main concerns for many people is the large shell of the main units. My ears are average size that can wear most of IEM available in the world (but a bit struggling on Monarch II). And I found myself that I can wear MP145 completely fine even with any stock eartips. Changing to Spinfit W1 just for better isolation and more secure due to deeper insertion and stickier surface. One thing to complain about is the edgy design that I really don’t like. It seems to be prone to scratch or color chipping around the edge in near future. The housing has good ventilation so I don’t feel any pressure buildup during long listening sessions.



Sound:

For listening, I mainly use MP145 with pink filter and stock cable setup. Together with Hiby R3II dap, Fiio BTR15, Topping G5, and Fiio KA13

Low-end provides very good bass textures. Thick and full sub bass and mid bass. Punchiness is fast and strong in mid-bass region. But its slightly lack of rumbling in sub bass region. I can feel vibrancy from the acoustic double bass clearly. Bass got quite good control. There is no bleeding or overshadowing into other frequencies. Quantity is a bit above average. It is plenty for me, but cannot say it is much enough to call a bass head.

Mid frequency has a hint of warmth in both male and female vocal. The vocal is lush, smooth and forward. For some might worry about the mid dip which usually happened in many Planar-IEMS but it not for MP145. And yes it is not kind of the cleanest vocal. I prefer this organic sounding more than analytical clean and lean sounding. The instrumental sounding is quite defined yet smooth with good clarity. With the stock cable can feel that vocal is a bit overshadowing the instrument if you are that picky. (Solution = Re-cabling)

High-end provides crips, clean, airy, yet neutral treble with fairly good extension. I cannot notice any planar sheen for the MP145 which amazes me. Micro and Marco detail are presented quite well in this region without any piercing to made my ears fatigue in long listening sessions.

Stage and Imaging: I found MP145 provides relatively large soundstage in terms of width, depth and height. Also with its precise imaging. I cannot find anything to complain about on this topic.

Tuning nozzle filter:

Silver (treble): This is my favorite one. It’s boosted a little bit of treble but gives you much more openness in overall sounding. Some might find a very slightly hint of sibilant in female vocals with these silver nozzle. But for me it was totally fine.

Pink (balance) and Red (bass) nozzle: I found both of them sounds quite similar to each other. Pink nozzle will noticeably tame mid-high and treble to be less pronounced. Red nozzle will provide a bit more bass note weight but less airy compared to pink one.



Drivability:

I found the ease of drive for the MP145 is just average. Not too sensitive but not difficult to drive. I tried Apple Lightning to 3.5 dongle and it can sing perfectly at 60% volume.

Re-cabling:

Even stock cable is already doing fine. But I found its tuning is tend toward larger imaging of vocal. So it could overshadow some details of the instrument. Most of the cable I had tried made MP145’s vocal less forward, less warmth, and more neutral. I found it’s perfectly matched with NiceHCK Dual dragon. Which gives better resolution, better separation in width and depth while it does less vocal sacrificing than any other cable that I tried.



Comparison:

VS Letshuoer S12 pro.
- I used to own Letshuoer S12 and S12 pro once. I found MP145 tuning is tend to be similar to S12 pro with being more neutral, more meaty and lushness and being superior in overall stage and imaging. MP145 is much smoother with no piercing treble or planar sheen to be notice like S12 or S12 pro.

VS Binary x Gizaudio Chopin
- Chopin got more sub bass rumble and punchier bass with similar speed of bass decay. However, I found Chopin can do better in terms of bass definition. Mid is cleaner and leaner in Chopin while it’s thick, warm and lush in MP145. Chopin is more aggressive in mid-high region. Treble extension is better on MP145 while Chopin have more sharpness, more edgy in treble region. MP145 got an upper hand in stage width and height. But Chopin did better in the depth.

VS Sennheiser IE600
- I know it is unfair comparison due to the price difference. But since it is my benchmark IEMs so I decided to do.
IE600 has more precise imaging. Better in overall technicalities, better bass definition and resolution. Overall sounding of IE600 is prone to bright side. While MP145 is meatier, lush and warm with larger body of the vocal and instrument. Even MP145 sounds less neutral but It’s sound “fuller” and “more pleasing” to me while it has similar of stage width and depth to IE600.

Summary
Hidizs MP145 is a pair of Planar magnetic driver IEMs that easy to drive. Have lush and warm sounding with good amount of bass, nice treble extension, airiness, and details. Also with amazing size of stage and precise imaging that not easy to find in the IEMs in this price range. While it has to consider about the large size of housing shell that might not fit for someone who has smaller ears. Tips rolling is a must, while re-cabling is an optional.

This is my first review and also my first planar IEM which I purchased
on the Hidizs kickstarter promotion.

Hidizs supply the MP145 in a solid box with small, med and large tips

to cover bass, balanced and vocal sound profiles. The supplied cable is

high quality but I did find the ear hooks extended too high to anchor the IEM.

Switching to an alternate cable that wrapped closer to my ears made the IEM more stable.

The supplied tips work ok but the nozzle is large in size and I found using a softer tip

By TRN allowed a deeper and more secure fit. Once fitted the size of the MP145

Is not noticed and the metal alloy is fairly light.





Drivability:

The MP145 has a sensitivity of 104db and resistance of 30 Ohm which makes it easy to drive from most dongles. I use it with a Hiby R3 DAP on high gain and while its sounds fine on medium volumes its really comes into its own with application of more power. The sound seems to expand beyond the head, and it never gets harsh or sibilant.

Sound quality:

This IEM is superbly balanced from sub bass to detailed non-fatiguing highs. The mid-range is uncolored and natural sounding with vocals placed perfectly in the sound mix. Others have commented that its sound signature is more closely attuned to a dynamic driver sound. There is no planar timbre that I can detect. Music is presented as recorded. Poor recordings are obvious and very well recorded artists excel with this unit.

Bass:

I like my bass. My favorite two IEMs are the 7Hz Legato and the classic V shaped Ikko OH10, both renowned for having deep impactful bass, so when I tell you the MP145 keeps me happy bass wise, believe it. Sub bass is well present, and bass heavy tracks are not lacking. Drums sound strong and natural, bass lines are full and none of this interferes with the rest of the sound spectrum.

Midrange:

Balanced, natural, airy, uncolored. Vocals are clear, present, well placed in the mix and tonally very enjoyable.



Treble:

Detailed, extended, unfatiguing and everything I though a planar would provide. I am hearing details in tracks that went un-noticed with my other sets. A note on the tuning nozzles. I have settled on the balanced rose gold nozzle which suits me well. This combination with TRN T ear tips (which add vocal clarity and expand the soundstage) gives me the sound I am after. I tried the silver treble tips and the high frequencies are more pronounced while the bass is not affected. The bass nozzle did not add large volumes and seemed to throw the tonal balance off to my ears. The lower midrange frequencies destroyed the perfection I had been hearing.





Soundstage and imaging:

This is the first IEM I have experienced that extends beyond my headspace in the manner of a over ear open backed headphone. Layered tracks with backing vocals sound amazing with the Hidizs.



Conclusion:

I’ve never owned a planar IEM before and I picked a great one to start with. Other reviewers have compared the MP145 more than favorably with existing planar units and I think you can’t go wrong with the Hidizs MP145

Review Of The Hidizs MP145​

Introduction​

In addition to making high-end digital audio players and dongle digital audio processors, Hidizs is also an IEM manufacturer. Despite the fact that I have never had the chance to test their stuff. They have a large fan base that praises their work and customer-facing approach, based on what I have heard and read. They recently dabbled with planar technology as well, producing the Hidizs MP145, the first planar IEM. I will be evaluating it today, but first I would want to address a few points.

Disclaimer​

*Since this unit tour was organised by the kindly people at Linsoul, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “MP145.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the MP145 based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

A 14.5mm planar magnetic driver is incorporated in the MP145. The aluminum shells include a faceplate patterned after a whale's tail with Rorqual pleats. The fit and isolation of the shells themselves are excellent, but they are a bit tacky to keep in place. Longer usage periods throughout my tests were a bit difficult for me because I felt uneasy due to its heavy weight. The four-strand, high-purity, single-crystal OFC cable that comes with this IEM is 1.2 mm long, with a two-pin connection on one end, and terminates in a straight 3.5 mm plug. In addition, there are three high-pneumatic sound tuning filters, nine pairs of eartips, and a storage bag. Regarding the technical details, the sensitivity is 104dB and the impedance is 30 Ohms. The range of the frequency response is 20 Hz to 40 kHz.

Sound

The sound quality of a full range planar IEM was introduced by timeless which showed the capability of a driver which can also be tonally correct and which made it a stepping stone for other IEM manufacturers to follow on, but as soon as the other IEMs got involved various sound tuning were established, ultimately expanding the horizon of what a planar can do. The MP145 is a new timeless around this time which I find thoroughly improved not only in tonality but in technical performances as well. The MP145 clearly swoop the board and established a new benchmark, specifically for the IEMs around this price. Coming to the core of the MP145, The sound is very close to LETSHUOER S12 but with better control on the response in the upper mid range and lower treble producing a tamed yet with improved details in sound. Basically the whole hit frequency spectrum follows the S12 with a better contrast in sound and technical performance but I won’t say it is a S12 killer, the reason being that the bass has a unique role to play and that is the introduction of the tuning nozzles which I will discuss about later on. Let’s dive deep into the sound and talk in detail.

Treble​

The better and crisp treble is what I heard out of the MP145, the treble region is detailed, clear and crisp without any sibilance or shouty response which the old generation wasn’t immune to, the treble has a better quality with a metallic timbre which subdues it’s wet response and keep the sharpness which might come as offensive at bay. The upper treble has a nice extension and the presence of air is fairly large which makes it sound a little better in spacious sound than the other planars like Talos, Timeless, P1 Max, etc. The vocals have a distinct quality and a proper clarity in the notes which makes it refine and moving to my ears. The instruments have a precise control on the notes presentation and allows a crisp response which comes across a little lean and sharp sounding while no irritating response is introduced. Even though a better grasp of energy and forwardness may be found I the S12 but the precision and control of the notes identity is promised with MP145. The lower treble same regime and allows the notes to produce in a more forward approach and tactically clear sounding, as the notes hits you and with the planar’s prowess resolves super quickly. The vocals comes across very clear and detailed as well as the instruments blends in without interfering with the vocal presentation as if it is complimenting them. The vibrant response and somewhat of an aggressive approach makes it sound energetic as well as captivating. So all in all the overall presentation of the treble region is crisp, detailed and mature sounding.

Mid Range​

Although I am quite certain that it the best vocals have heard on a Planar, I can at least say that if the mid range lacks in, it would be the warmth and dense response. But for a person like me who prefers a neutral with sub bass boost is actually a compelling sound signature of the MP145. The mid range offers the same resolution of clarity and forward response yet I would’ve preferred more note weight and subtle quality of warmth, yet I still find the vocals to be very impressive due to it’s light but not lean quality. The upper mid range maintains the same energy because of the coherent flow of energy allowing for a linear response. The vocals and instruments have a frontal approach which allows the details and clarity to come across as well as the notes quality of being distinct very audible, the wet metallic timbre is at the lowest it seems which makes it a more correct response from my perspective. The lower mid range has a different story because even it is a improved planar driver the rounded and warm approach is difficult to pursue for it, because of such a presentation, the notes doesn’t feel vague or dense rather the details produced even in a tad subdued lower mid range is surprising for me, of course when it is being compared to old generation planers. Now knowing the vocals sounds clean and the instruments sound a bit dull yet fine, I still find the response immersive. Therefore the overall presentation of the mdi range region is forward, clear and immersive sounding.

Bass​

When it comes to bass, the very defined presentation just puts all to shame but of course when I am talking about the texture and the details, but when it comes to whether it sounds organic, think or natural; I believe that the Kiwi Ears Melody would literally exhilarate the MP145. But that would an unfair comparison as the tuning is diifferent and the driver quality as well and also that I haven’t even talked about the tuning nozzles which helps enhancing the bass. So while keeping the standard tuning filter screwed on the nozzle, I find the bass to be precise and punchy rather than slamming or stimulating. The emphasis is on the sub bass and the extension goes deep which helps in producing subtle rumble with presice resonance in the ear canals which is satisfactory in its own way. The bass’’s physicality is not what I usually find enthralling but the quality of notes it produces shame other drivers as the control over the bass region whether it is the mid bass or sub bass, I find it quite captivating and thrilling to hear, to best explain it simply -- Different bass notes on different octaves and dynamics were easily recognised and felt which was an eye opener, but I would be exaggerating because at the cost at which the MP145 are offered is stunning, but of course it is a perception of what I believe in. Whether it is the punches or rumble or thumps or slams, the do not sound overpowering nor does they sound loose or exploiting. Hence the overall presentation of the bass region is detailed, controlled and precise.

Technical Performance​

I don’t that there is any full range Planar IEM incapable of impeccable technical perfomacne, with that said I believe that the MP145 is technically very resolving. If it is the imaging or details or separation or speed, I think that the MP145 rules all the other Planar IEMS out there, of course I believe not that I am arguing. The quality of details and the way the notes presented has really improved from the previous generation of the planar IEMs. The transient and clear response make it a very technical IEM yet the wet response is a downer for me but can’t be helped though. Let’s discuss more in details.

Soundstage, Sound Imaging & Separation​

The stage is averagely wide if compared to other full range planar IEMs and even the IEMs above the price bracket, the experience is impressive and the quality of the imaging is very sharp and clear which enthusiastically impacts me. Whether it is distinction in notes or the distant nature of theirs, it is very easy for me to pin point the source.

Speed & Resolution​

The resolution is proper and precise which helps in expressing the details whether it is micro or macro fluidly and prominently. There is no doubt that I find Planars to be extremely fast resolving due to their attack and decay being super quick in action.

Sound Impressions ​

Tuning Filters​

Rosegold/ Balanced/ Silver/ High Frequency - I’ll be honest come out straight, I audibly heard or feel no difference in the balanced or high frequency tuning filters, and that is when I did B2B comparison in between after giving each 10 mins of time. Trust me when I say that the sound that I discussed in details before is the same for either the rosegold or silver nozzle. Obviously it is an observation of an individuals and others may hear better. But it is what I actually found.



Red/ Low Frequency - Now the low frequency nozzle which is in red in colour actually makes sense, by which I mean an audible difference. The red nozzle helps in taming the aggressive and forward response of the upper mid range and brings out a balanced response rather than a somewhat of a V-shape sound. Due to the subdued response the bass enhances in the overall mix and produces more prominent bass presence. Although the details take quite a hit in producing the crisp notes, it basically reduced the effect of the wet quality and metallic timbre in the mix. And surprising feels warm in response. This kind of response feels coming from entirely another IEM which is smooth and balanced sounding. So I feel that there is definite potential in the tech and material used.

Sources​

Sony WM1A - listening MP145 with the WM1A, the pairing with the standard tuning nozzles sounded vast and clear and more enhanced in dynamic response. While I found that MP145 with red nozzles weren’t a good pairing from my perspective as the sound subdued in terms of vocals and instruments sounding dull and lifeless. The clarity felt more intriguing as there was a sense of natural response but wasn’t coming out clearly though the sounding such made it sound really smooth and expressive which felt like the best pairing.

Tempotec V6 - while listening MP145 with the V6, the energy held within MP145 feels exploited and makes it sound more transparent in the response while not correcting or disrupting the response. Although the metallic timbre is audibly a nuance when hearing high energy complex tracks or bright tracks. Though the quality of notes is refined and basically correct in expressing clarity. The derived observation is after examining all the tuning nozzles, but I were to point out, the pairing MP145 with red nozzles screwed on pairs perfectly with the V6.

Conclusion​

To end this review, as I mentioned that a new benchmark has been set with the introduction of MP145, I find it sound improved and challenging enough to bring other full range Planar IEMs around this price to their knees with such intricate details and level of clarity while maintaining the composure and integrity of the notes is blissfully interesting to listen to. The more I listen to it, the more I find it enthralling to listen to, hence I wholeheartedly recommend the MP145 to anyone who wants to upgrade from their older sets of Planers.

There are a lot of brands I haven't worked with. In this booming world of audio products it's hard to keep track of brands. I know, I know Hidizs is not new but they haven't been able to capture the imagination of the market like other chi-fi brands. But it's seems like this is about to change. They used to have a good range of DAPs but it's limited to AP80 series now. What they have been improving with are their USB dongles and IEMs and their new planar based IEM, MP145 housing a 14.5mm planar driver has taken the industry by storm. Currently available on Kickstarter with various combo offers and early adaptors discount, it comes in 2 colors, currently available at $159 and goes up to $200. It goes head on against a lot of IEMs in this price and I will compare it with the Akoustyx S-6, DDHIFI Janus 3 and Tri i3 pro IEMs.

The best thing I can tell is, it's much better than the wooly, thick and blurry sounding 7hz Timeless and has much better control and composure than the Moondrop Kato. It has better definition and clarity than the Dunu Falcon Pro. It definitely looks like a superb IEM at this point of time. Let's find out about this IEM.

This IEM has me baffled. I had never seen an IEM with hard case. This is the first and it's much easier to understand why no brand likes this ship their IEMs in hard packaging. They are easy to break and my unit too had chips coming out of it. They are nicks, nothing serious but it's not ideal.

Nevertheless, open the box and we get to see the IEMs upfront. We have the tuning filters and the cable placed inside a paper box under the IEM while the tips are stuffed inside a paper box at the bottom. We are getting a generous set of tips, 3 pair of vocal, 3 pair of bass and 3 pair of balanced tips in S/M/L sizes.



CABLE:

MP145 ships with a 4 core silver plated single crystal OFC cable and as available in both 3.5mm and 4.4mm versions. I have the 4.4mm version with me and I like this cable. Its light weight and the cable has little to no memory issues, isn't bouncy and one doesn't need to worry about microphonics either. The parts used are of decent quality too. The 4.4mm jack is a bit on the larger side but the Y splitter, cable slider and 2pin connectors are minimal in size. The cable guides are fairly relaxed and dont exert much pressure on the ear.



BUILD QUALITY:

This IEM follows the build quality norms of both Hidizs and other competing IEMs in this price. Hidizs has made a lot of IEMs with metal shell and just like the Shuoer S12 pro, Tri i3 pro and 7hz Timeless we are getting an all metal build quality. Thanks to this one doesn't need to worry about durability, it will take good amount of rough handling without much issues. We are getting an interesting looking back plate while the nozzle has swappable filters to take care of the tuning flexibilities. One thing I would like to mention is the size, it's big, and will not fit those with small and shallow ears.

Ergonomics are decent too. There are no annoying edges to worry about. Thanks to the well managed weight and aptly deep nozzle, the ear pieces do not feel heavy.



PAIRING WITH SOURCES:

We have a huge 14.5mm planar driver to power here but guess what, it's not super hard to drive. We have a respectable sensitivity of 104db and resistance of 30ohm which makes this a reasonably easier IEM to drive out of our mid range USB dongles and I am having a blast with them. I got the DH80s bundle and this pairing is very good. Yes, getting a more capable source will definitely bring improvements of it's own, even the more capable Beam 3 plus has better air between instruments and a bigger stage but the DH80s doesn't leave a lot to be desired. I am getting very good layering and separation with good amount of air between instruments. The stage isn't small or clumsy, imaging too is very good.

Is it wise to drive a planar driver IEM out of a mobile phone? No, definitely not. It's ignorance of the fact that planar drivers need power and even if this IEM doesn't need much power, it still is a planar and needs more power than usual IEMs.



SOUND QUALITY:

I am not new to this type of IEMs. I have seen brands doing a lot if things with their planar based IEMs but I have to admit, after the Akoustyx S-6 the MP145 is the next Planar based that has impressed me the most. It's 14.5 mm drivers are tuned to deliver class leading SQ with a reasonably V shaped signature that doesn't feel aggressive or lean at any point. We do not get a dull region either and the best thing I noticed is it's softer edged presentation.

Tonality and timber are very similar to what we get with other Planar based IEMs. I am using vocal tips and DH80s and Shanling UA5 as source for this review.



BASS:

MP145 has a typical planar tuning yet it is different. We get full bodied notes but true to planar IEMs these notes decay so fast that it doesn't move a lot of air, leaving a lot of air for the rest of the spectrum to breathe.

End to end extension is decent. Sub-bass is good and has decent rumble but isn't very deep. Mid bass is more prominent with a sizeable body. The area of impact is big but it isn't heavy or very punchy. Dynamics are decent, they do tend to end up in the mid bass region. I have heard better dynamics from similarly priced IEMs but MP145 makes up with it's control and discipline. We do get a below average layered hits, the notes do not have enough air and separation between them. It doesn't get tiring or boring but those looking for a heavy hitter will find this not heavy enough. Upper bass is nicely presented with decent clarity and details but I wish the mid bass was a bit less dominant.



MID RANGE:

Oh.. the clarity!! It puts a smile on my face. It delivers so much goodness that if we do not mind the limitations of the bass notes, this IEM can easily take on $250 IEMs without breaking a sweat.

Unlike most of the Planar based IEMs, MP145 doesn't have any obvious flaws. Yes, the V shaped signature has a bit of pop to the vocals but we are getting excellent clarity and details. The drop in energy is much less and doesn't sound sharp like the Shuoer S12/pro, while the clarity, layering and separation are similarly brilliant. We get reasonably accurate sounding vocals. It's faster decay does take away the extra bit of throatiness and grunt, making the timber and tonality a bit dry while enhancing the transparency. Even when timber and tonality are slightly on the less fuller side we still get beutiful texture with both male and female vocals, they are a bit subtle but if you are paying attention, it's highly enjoyable. Notes are sooooo beautifully presented that it's hard to complaint about minor niggles. Yes, this is not a very analogue sounding IEM but the contrast and layering are brilliant enough to stand out.

Instruments have very good clarity yet have no sharpness or aggression to worry about. In fact this presentation of instruments is more contrasty and cohesive than the DDhifi Janus 3. There is a bit more energy in the upper mids but has no sibilance or sharpness to write about. It's not dull or smooth. If you want silky smooth and relaxed mids, planar drivers are just not it.



HIGHS:

What these planar drivers are capable of are some of the best treble response and MP145 is no exception. We get excellent transparency and superb control too. It has sparkly notes, impressive clarity, clear of any unwanted sharpness while being cohesive and engaging. Treble extension is superb too, yes it doesn't carry a lot of energy into the upper treble, especially to keep the harshness away but the lower and mid treble regions aren't rough or raw. They feel a lot more uniform and sorted than the competition. MP145 has superior control and is nowhere as sharp as the S12/pro and Talos in hybrid mode. It isn't as dull and lifeless as the SeekReal Dawn and Timeless either. Notes have very good finishing definition but aren't sharp or too energetic.

Layering and separation are superb with class leading amount of air between instruments.



FILTERS:

This is a decent way to induce changes in frequency and I am liking it. It doesn't feel odd or off with any of the filters but it's not much different either.

RED FILTER (BASS): The red filter is supposed to be bassy but what we get is a bit more weight behind the lower end notes. The do not gain extension but have better texture and more layers making the whole experience more gripping while the mid range and vocals remains exactly same. We get a bit of changes with the treble though. The lower treble is nearly same but the mid and upper treble are a bit less energetic. The upper treble can feel a bit dark to some but It is plenty good. The do not have tall notes but do not compromise with the transparency or air either.

SILVER FILTER (HIGHS): Now this is the kind of treble presentation we get with the Shuoer S12/pro.

Oh man.. It's hard to tell the two IEMs apart except the bass. S12 pro is more bassy and more V shaped.

We get exactly same bass and mid range but the treble gains the extra sharpness and notes gain height. These notes are borderline tiring and can be uncomfortable for most of us.

I usually feel the stock filters to be the best but this time around I find the Bass filters to be the best suited for longer listening sessions. The Red filter is calm and relaxed, doesn't hound, delivers a more contrasty and sonically better experience.

STAGE AND IMAGING:

Few years ago it was criminal to expect a well developed stage at this price but guess what, MP145 has one of the best stage expansion and imaging. Aided by one of the best layering, separation, control and precision, we are treated with one of the airiest presentation. It has well expanded 3D imaging with accurate cue placement. Yes, the notes in the mid range are a bit less tall while the bass and treble notes are taller. Most of the bass and vocals are placed inside the head while some of the mid range and treble notes are projected out of the head. Notes have a more complex presentation with presence both over the head and behind the neck. Instrumental distribution is not the most even but there isn't much to complaint about either.

In general this stage has superb height, very good width and class leading Z axis depth. Depth is much better than anything else in this price range.


COMPARISON:

I have tried a lot of planar based IEMs. I have reviewed a wide variety of these. Starting with the 7hz Timeless I have reviewed the S12/pro, Akoustyx S-6 planar only IEMs. I have reviewed a couple of Planar based hybrid IEMs too, Dunu Talos and SeekReal Dawn to name them. All these IEMs were either sharp and aggressive or dull and smooth. They weren't something one can label as "Good for all". It's the temperamental nature that most of the consumers were happy with, mostly because there wasn't a decently balanced option. S12/pro and Talos are V shaped with sharp highs and thin mid range notes while the Timeless and Dawn were unnaturally thick and smooth. Timeless is seriously veiled, the worst of the lot.

MP145 is in the V too. It has a bit of pop to the vocals too but guess what.. We are getting some of the best control and definition from a planar driver IEM. The highs aren't sharp and sibilant like S12/pro and Talos without compromising with extension or clarity. The only other planar IEM that matches up to the MP145 is the Akoustyx S-6. While the S-6 a bit more balanced with leveled mid range, MP145 has less tall mid range notes.

If I have to recommend two Planar based IEMs, they have to be MP145 and Akoustyx S-6. These two can be easily recommended to anyone and they won't feel like missing out or being hounded at.


CONCLUSION:

What we usually want from an IEM? Good details, good clarity, engagement and it should not sound harsh or uncomfortable. MP145 has superb details, excellent clarity and much better control over sharpness than S12 pro and Talos.

I have no issues crowning it as the best planar based IEM under $150. It and the Akoustyx S-6 are the two best IEMs in this price.

If you enjoy a slightly aggressive presentation, MP145 is the best IEM to get.

We will be reviewing Hidizs's new planar in-ear monitors. Many have awaited Hidizs's planar earphones and led me to think, is it worth the hype it deserved? Let's find out!

I have my own share of experiences when it comes to planar in-ear monitors, I have tried the LETSHUOER S12 Pro, TANGZU Zetian Wu, MUSE Hi-Fi Power, and the KZ X HBB PR2.I am hoping that I could share my insights with Hidizs's new in-ear-monitor.

PACKAGING​

The packaging of the Hidizs MP145 has the typical Hidizs style, featuring the brand's logo and a preview image of the IEM on the sleeve. Notably, the box is crafted from plastic, which represents a different approach from their standard packaging materials. However, this choice raises concerns about the durability of the packaging during transit, as plastic tends to become brittle and may break if mishandled. Nonetheless, it has effectively safeguarded the item during shipping.


Upon opening the box, the contents appear to be neatly organized and straightforward. Here's what you'll find inside:

• HIDIZS MP145 drivers
• 3.5mm cables
• 3 pairs of bass eartips
• 3 pairs of vocal eartips
• 3 pairs of balanced eartips
• 3 pairs of tuning nozzles
• Leather earphone pouch

It's worth mentioning that the included leather earphone pouch may not be personally useful for those who find the earphones rather bulky. The pouch may not provide as effective protection as a dedicated earphone case would for these particular earphones.

BUILD QUALITY​

The MP145 Driver is built like a robust tank, boasting both bulkiness and sturdiness, which certainly catches the eye due to their bulky build. However, in my personal experience, I've found the fit of the MP145 to be uncomfortable, primarily because the included eartips don't align well with the MP145's nozzles.They fit excessively snug, requiring substantial effort for removal. Consequently, I opted for my TRI Clarion eartips, which feature larger bores and fit the MP145 perfectly, like a glove. It would have been beneficial if Hidizs had conducted some thorough testing to ensure a more comfortable fit with the provided eartips.The cables are okay, but these are not modular and only comes with the 3.5mm plug.

SOUND​

The sound profile of the HIDIZS MP145 plays around the U-shaped sound-signature, and may still vary depending on the nozzle used. However, it's clear that the HIDIZS MP145 tends to lean towards a warmer sound signature while making an effort to maintain a sense of neutrality.

BASS
The bass delivers a commanding punch and subtle yet resonant rumbles while exhibiting excellent control and swift transient response. It maintains its distinct character without bleeding into the midrange, providing a sense of power and coherency. The primary emphasis here is on resolution, impactful punches, and swift attacks, rather than focusing on deep-reaching bass weight. As a result, it may not be the preferred choice for those passionate about deep bass.

MIDS
The midrange exhibits a subtle recession, enriching male vocals with added depth, while female vocals adopt a more mature and euphonic timbre. Vocals maintain a pleasing and natural presence, avoiding an overly distant or hollow quality. Instruments receive some attention, preserving their natural and uncolored tones without excessive vividness. The upper-mids display a smooth, subtle gain with a non-fatiguing sound, making it especially favorable for individuals sensitive to harsh frequencies.

TREBLE
The treble performance falls somewhere between not being exceptional and not being subpar. It carries a remarkably inoffensive and smooth timbre. It's worth noting that some listeners might perceive the treble as lacking in energy and sparkle, which is entirely understandable. This characteristic is different from the typical planar earphones that often exhibit a distinct "planar" timbre, emphasizing the higher frequencies, but occasionally resulting in a shouty or shrill quality. Still, the treble is no slouch, it still has good precision and attention to details while subtracting the issues surrounding some "planar" earphones.

TECHNICALITIES
As far as technical aspects are concerned, this isn't somewhat groundbreaking but it is above average with decent soundstage with enough width, height, and depth that are spacious enough for my head room. It demonstrates a commendable separation and layering, allowing me to discern well-organized layers for each instrument. It adeptly handles complex tracks with ease, boasting excellent resolution and respectable detail retrieval.

TEST TRACKS​

DISCLAIMER: For my testing purposes, I don't use Spotify. I have high-resolution copies of my test tracks, maintaining a backup copy of these playlists on my Spotify account as a reference in case I lose my playlist.

CONCLUSION​

Pros:

• Excellent balanced sound
• Tuning filters offers slight but noticeable changes to cater your preferences
• Build quality is outstanding
• Thick, commanding bass
• Lush and euphonic mids
• Inoffensive treble
• Decent technicalities
• For $199, these are okay

Cons:

• They are BIG
• May have fitting issues for smaller ears
• Eartips are very incompatible and can be an effort to remove
• Earhooks are ANNOYING
• Needs decent sources to perform effectively

The oversized design may pose challenges for individuals with smaller ears, and the nozzles provide a secure grip with the eartips, making them somewhat challenging to remove, especially if you frequently have a rotation of eartips. If these aspects are not problematic for you, these IEMs are visually striking. Their balanced sound, with the option to make slight adjustments using the nozzles, positions them as a strong contender in the sub-$200 IEM category.

TONALITY: 8.5/10

INTRO

Hidizs has been around for a long time, at first they were specializing in digital audio player and portable DAC-AMP but then begin to make their hand son IEMs of all type from single DD to hybrid to multi BAs.
Their latest release, the MS3 hybrid IEM, earn quite good praise including by me for plain technical performance sound value.
But I always had an hard time to appreciate tonal balance of Hidizs IEMs I've tested.
Will this change with their newest release call MP145?
I do hope so!
With a MSRP of 199$ that go 110$ for early birds Kickstarters deal, the MP145 is a planar IEM using a large 14.5mm planar driver and having a special acoustic design, inspired by whale shape but taking advantage of it's size potential too, in term of acoustic chamber.

Last year was overwhelming with chifi planar IEMs release, while in 2023, the MP145 come as an exotic offering. Let see if this IEM is just a looker or can deliver a sound value and musicality that worth our hard earned money.



CONSTRUCTION-ACCESSORIES




The MP145 design is loosely inspired by whale tails for the overall shape and texture lining and rorqual pleat for the 2 wide venting hole that act as semi-open back.

And they are ''whalegantissimo''! Very big and chunky housing, biggest one in term of planar, 7HZ Dioko being close second. Yet, they are lighter than those Dioko....and so so better sounding but thats for sound impressions part.

The design is very eye catchy, so you can't be an undercover agent walking on the street with those, it will attract some attention surely. To my eye, they are beautifull and teh cratmanship is very impressive, their no other IEM on this planat with similar design and it's a plus. If it wasn't for oversized size i would say they would look very elegant, but in the hands they do.




The built is 100% made of alluminium alloy that seem of very good quality and not easy to scratch too, which is a big plus (no scratch to be found after more than 1 month of intense abuse).
While the back has sharp edge that magnify precision of carved lining and shape, the front has an ergonomic organic shape that is smooth and quite comfortable even for long listening session.

But this is from somebody with big ears, so for very small ears I would be concern about size for a fit free of unwated ears pressure.

The nozzle is average long but quite big and thick too, another aspect that could be problematic, but this time for small ears canal. These aren't thinked for deep fit too.

The 2pin connector are thightly embeded in the housing, its not recessed and feel extremely sturdy, with fine cratmanship free of imperfection like loose space around connector.


Now when it come to the included cable, i was impress by the good quality of it as well as the choice for 4.4mm balanced plug. Its a 4 strand silver plated single crystal copper cable that doesn't add or stole anything to sound rendering, so it's all good.



When it come to packaging, it's minimal and elegant. We 9 pairs of 3 different silicone eartips models. We have 3 sound filters nozzle. And a carrying pouch. Sure a proper carrying case would have been nicer, but it's quite nit picking and will depend your personal need.

SOUND IMPRESSIONS



Since I wasn't biggest fan of all other IEMs from Hidizs, let say i was a bit worry to find the MP145 underwhelming, I mean, tuning planar isn't easiest thing and they were begining to earn experience with hybrid that permit the MS3 to achieve a more coherent balance....so why going planar?

I don't know, but let say the positive surprise of very first listen was near overwhelming and quite a big shock. Now I want Hidizs to just make planar IEMs!

Very first thing that wow the listener is the gigantic soundstage, which is clean, ultra open and holographic and notlacking in wideness, tallness and even depth. So it does confirm something i've conclude with my 10 years of more than 300 IEMs testing: housing size does matter when it come to spatiality. And since this housing is near as big as a whale, it deliver a ''whale-gantic'' soundstage.

Then, it's how deep the bass dig and rumble that hook me. Then how smooth yet clear and open are the mids. Then, how extended, snappy and sparkly is the treble, which is a big surprise since it's rare to have sparklewith Planar, 2 other example are Tinhifi P1plus and to a less extend, Tangzu Zetian Heyday.

So i'm happy to say it's not a pure harman tuning balance we have. It's not about bright shouty presence boost here, in fact, upper mids are smoothen.

But we have 3 tuning choice. Treble and balanced are near identical apart slightly less bass boom and hint cleaner sharper treble for Grey nozzle. The Bass (red) one is more consequent in change, its darker, warmer and hint bassier, bass is thicker and not as well separated, mids feel thicker in macro dynamic, less airy and more laid back.
For this review I will focus on Balanced Gold nozzle, which is the best sounding and more coherent tuning to my ears.
Overall balance of those 3 go from warm (red nozzle) to smooth (gold nozzle) and bright (silver nozzle) U shape.

What the MP145 don't deliver: hard mid bass punch with fowards kick presence, agressively bright mids, thick and dark mids (well ok Red nozzle deliver that), very dynamic mids, neutral tonality, treble head tonality (ok, treble nozzle isn't far from that), dark treble...

What it deliver: wide mellow slam, deep resonant rumble, enormous soundstage, transparent and smooth mids, versatile tonality, U shape balance, crisp snappy and fast treble, excellnt layering, lush vocals,


These aren't bass light IEM and deliver well felt slam that have dominant sub bass boost but don't sound thin nor dull boomy. For those use to U shape IEMs, they will find the MP145 to have enough mid bass punch, while those that are all about V shape basshead IEMs will find it lack a bit of it.
To me, it's evident the kick drum take second seat when bass line happen, but the layering is well done and transparent, just not hefty in multi dynamic so we have this wide speedy slam that open in space and stay in back of other instrument, thanks to fast transient attack of planar driver that act a bit like hybrid DD+BA here in term of extra layering capacity.
But this slam isn't thin boom as said, its not like those Moondrop with sudden boost that begin late in 200hz section, we have air density and rumble vibrancy, and the hit is well felt, more so than well define.
It's quality meet quantity here, and among best bass performance I have heard with a planar, among cleanest, most extended and less euphonic one too.
Fast slamwith plenty of headroom, subtle texture edge, that can go brightish to warmish tone depending of the source.
If your a rumble lover, your in for alot of pleasure due to long effortless sustain-release.
The transition into lower mid range is natural, without sudden scooping that can affect tonality fullness.
With the Red nozzle filter, the bass will go warmer and thicker and embrace lower mids in a darker, less define in separation way wich will make macro dynamic a hint more muddy.

The Mids are open, lush and clean. They are smooth enough, non shouty nor sibilant. The lower mids aren't extremely boosted nor lacking, so we have slight thicknest and warmth going on in timbre, adding a sens of breathyness to female vocal and fullness to male vocal.
This is very unique and versatile mid range, male vocal are fowards enough without being plain dominant in the mix, female vocal are slightly more fowards, but still smooth yet nothing sound dull here.
Piano note have impressive natural resonance within a clean soundscape, it's note attack is fast and well felt but not hard hitting or very edgy in definition.
Saxophone offer open presence dense with textured air, presentation is neutral we can say with good transparency to permit a vast amount of instrument layering and commandable imaging. With artist like Sons of Kemet, bassoon and sax offer impressively readable layering.
I wouldn't say the MP145 are mid centric at all, nor the most natural in term of timbre, but it's among the best for a planar.
Definition edge is slightly softed here, explaining this lushness that meet gentle brightness kind of timbre. We don't have noisy planar tone, nor ultra bright one. With MP145 your in middle of vast mid range and center stage, yet you don't get lost in a muddy or overly homogenous macro dynamic.

The treble is the star of the show with the sub bass and extend far above 10khz, we have proper sparkle, snap and air for a planar, it's not the sharpest cleanest brilliance but it's there way more than with multi BA or hybrid, similar to DD, not as sharp in sparkle and clean in release as EST.
It's really a mix of texture crunchyness and airy sparkle release, which do well for acoustic guitat because it sound both full and crisp.
Its one of this rare treble that do good for both electric and acoustic guitar, electric guitar is rich in natural fuzzyness, dense distortion texture and a offer a wide bodied presence without screamy or shouty dynamic. MP145 are near perfect for rock, metal and jazz, only if this kick drum was a bit more hard punchy, but it isn't and as we know supreme perfection don't exist even in 10 times pricer IEMs.
But this isn't all, the percussions are very fast and controlled in attack as well as fowards enough. It's super easy to follow them and their separation is excellent, their timbre is full and when they need the metallic rendering, they get it. The natural decay is well presented and realist, not scooped, linear in release.
So we have the abrasive bit and the sparkle, the crunchy snap and the air, what to ask more? Perhaps even sharper and cleaner extension like the Tinhifi P1plus?
And now for infamously hard to render instrument: the clavichord. Firstly, separation of low and higher note playing is very well done, but the frequencies range of this instrument is very peculiar and have harmonic that go up to 4.6Khz with its fundamental in 770hz, so like the piano, the presentation is a bit dry and lean but full sounding enough, yet, it sound a bit distant compared to other instruments.
Nonetheless, after Tinhifi P1plus, it's most sparkly, extended and airy treble I've heard from a planar and it's more snappy than Tangzu Zetian Wu.

The soundstage literallty drive me euphoric. Their no doubt it's biggest headroom I get from a planar IEM, it's huge in all direction, but wideness is very stretched and feel like it go 1 meter at each side of your head, then tallness is impressive but half as long, then deepness is half wideness lenght too, all this doesn't give a hall or tunnel like presentation where you'll find yourself far from instrument since they come to you and float in this soundscape with an holographic layering.

This layering is what make the imaging appealing and intricate too. Even with busy track, it will keep up in multi layered macro dynamic. Layering in Y axis is easier to read than sharpe separation in X axis for less loud or dynamic instrument. Percussions too will be easier to pin point with precision.




SIDE NOTE:

The MP145 do benefit from good amount of amping like all planar, but they aren't hardest one to drive. At 30ohm of impedance and 104db of sensitivity, ill suggest a minimum of 100mW, but for achieving best technical performance it would be 200mW@32ohm and up, cleaner it will be, better attack control and soundstage depth will be. When well amped, the soundstage open up even more but since its so huge, even the Audirect Atom 2 can drive them OK and will not make bass distort, but a phone will not be enough and this very pairing don't do justic to technical performance of MP145. For crisp ultra open musicality, Moondrop Dawn 4.4 is good, for warm and slightly more mid centric musicality, Penon Tail is good too. Even the iFi Go Pod drive them well at 120mW gain.

The included wide bore eartips are good choice yet if you wanna open up the sound even more, the short wide bore as well as Fan2 blue ear tips are great choice.

Cable doesn't inflict alot on dynamic or timbre of MP145 and the stock one is good enough, especially in 4.4mm balanced format.


COMPARISONS



VS DUNU TALOS (1Planar-2Bas-200$)

Simply put: the Talos are among worst planar have ever heard so it's no surprise it sound so bad compared to MP145, and that in pure planar mode, which is better than hybrid mode, which is just plain unlistenable shouty trebly fest.

So, tonality is more bright neutral and lean with all main focus in uppermids with the Talos, its notably more agressive in lower treble as well as more shouty and fatiguing at high volume than bassier more U shape tuned MP145.

The bass is lean, anemic and dynamic less with hint of mid bass punch neutral way, notably less deep than MP145 which seem a basshead IEM compared to Talos. Kick drum is drier and clearer with Talos but not as round and heavy in not weight, Sub bass is more scooped, bass line are harder to feel and hear. MP145 offer wider and bigger slam, with deeper more vibrant and realist rumble and overall more lively dynamic.

The mids are warmer and smoother with the MP145, we have more low mids too, so vocal are fuller bodied and lusher while Talos is all about upper mids, its thin and shouty, female vocal timbre is grainy and spiky and induce way more sibilance. Instrument presence is more centered and compressed, while wider and more holographic with MP145. While shoutier, the dynamic isn't very energic with Talos, we have lighter note weight but edgier definition, it's this edge loudness that jump at us so at they end treble eat the mids here way more than MP145.

Then the treble isn't as full sounding as MP145 and keep hidden some part of percussions in favor of other sharper more brilliant one, so Talos is more spiky and have extra fake air that make us perceive cleaner and simplify highs rendering. Highs are thinner, this include high pitch instrument like violin that sound metallic and thin, percussion dont open up in sustain-release, so some of them feel more snappy but in an artificial way, the MP145 treble dig more sound info, is more wide open and freely layered, less trebly and have more natural resonance.

Soundstage is intensely wider and taller and deeper, Talos is very compressed and centered and unidimentional in comparison.

Imaging is edgier and more monitor like with Talos, but not as open in sound layering so it's flat monitoring, due to less mids warmth, positioning is sharper in this area.

All in all, Talos sound plain wrong compared to lusher balance of MP145. Technicalities are a bit similar, but unlike MP145, the technical potential is kill due to bad tonal balance and acoustic implementation of planar driver which sound very compressed in spatiality, lean in dynamic and dull and cold and shouty in tonality with a bright planar timbre to add to this. Well, i can add that even if MP145 housing is 2 times bigger, its notably more comfy than Talos too.


VS LETSHUOER S12 (1x14.8mm planar-150$)

Ok, now thats a more serious fight. Soundstage isn't lacking like with Talos so its less disconcerting to compare those too.

But it's not very similar in tonality, the S12 offer a brighter V shape which is in fact a hint less bassy in term of wide slam, its less extended and boosted in sub bass the the rumble feel scooped but the midbass punch is rounder and more energic, as well as more textured in presence, it feel thighter and faster but not as transparent and well layered.

Mids are more upfront and bright, we have more upper mids bite and presence texture, less transparency and less wide in presencethan MP145, which have breathy lusher female vocal, less promptto sibilance or too loud gain. Mids are more wide open and hint leaner with MP145, layering is better and we have less macro euphony going on that affect busy trrack, which can go saturated a bit with S12. S12 definition has less soffted edge, violin has more bite for attack, piano note a sharply define but not as weight, we can say mids are more intimate and clear but more condensed in center too.

Treble don't extend as far with S12, it have more lower treble energy, grain, texture and bite, so electric guitar sound fuller and more upfront but percussion can get lost in the mix, treble isn't as snappy and way less sparkly, airy and open than crisper U shape balance of MP145. This time it's S12 that sound crunchier and thicker in term of treble, but this affect negatively high pitch instrument tone which is overly boosted in brightness and grain, less lush and smooth than MP145, its more fatiguing too.

Soundstage is notably wider, slightly taller and intensely deeper with MP145.

Imaging is cleaner and less compress in macro dynamic as well as more transparent and better layered with MP145.

All in all, I prefer MP145 lusher U shape balance as well as more natural and smooth timbre. Like with Talos, technical performance are similar but too compressed, and it underline the benefit of big housing as well as open back venting for planar driver to permit better macro dynamic rendering. This time, its S12 that is way more comfy, its smaller and as a perfect ergonomic shape, you don't look like a weirdo wearing those too.


VS RAPTGO HOOK X HBB (1planar+1piezo hybrid-260$)

Ok, I will not compare the MP145 to all planar I own, but feel the obligation to compare it to the very best one.
HBB feel slightly warmer and more W shape as well as even more holographic due to extra layering of upper treble from piezo.

The bass is thicker, more euphony and deliver heavier mid bass punch, the rumble sustain is shorter and less extended, bassline are more favorize with MP145 and bass is more transparent with less warmth bleed than HBB, is have wider resonance head room and more mellow mid bass punch. HBB bass is more tactile and round.

Mids are again thicker yet a hint more fowards in upper mids so female vocal are more upfront and bright. Male vocal are near identical, just a hint thinner and leaner with the MP145. Overall mids feel more open and airy with MP145, but leaner in center stage, its smoother, less prompt to pinna gain fatigue even if HBB isn't very intense in that regard. Mids are more transparent and cleaner and better layered with MP145, we have less bass bleed that darken definition crispness.

Treble is airier, sparklier and more delicate with the MP145. HBB have more crunchy attack, brighter tone, it's more abrasive in texture but i would not say it extract more micro details, the snappy attack is more dynamic and high pitch instrument or percussions more 3D, but more spiky too, i find highs more refined and balanced with the MP145 but not as catchy, again, the top is cleaner with MP145.

Soundstage is slightly taller with Hook X HBB but notably deeper and a hint wider with MP145, not night and day difference like with Talos and HBB have way bigger spatiality than S12.

Imaging is moe accurate with MP145, this is due to cleaner macro resolution and less euphonic mids, sound layering is superior in high frequency with HBB.

All in all, i would say technical performance of the Planar is superior with MP145, but mid treble is faster and snappier with HBB, tonality is more dynamic and punchy. I can't choose a clear winner here since I love both intensely.


CONCLUSION


Sometime, when you expect nothing, it's when you get everything.

This is what happen for me with MP145. I was very sceptikal about capacity of Hidizs to properly tune a bassy planar IEM as well as making it sound different enough of rest of planar offering that was flooding the market in 2022.

Since i own 10 other planar, i was worry it would be a sidegrade that will take dust and it's the opposite that happen, since those MP145 ''stole'' alot of listening time and is now one of my fav with Raptgo Hook X HBB, Tangzu Zetian Wu and Tinhifi P1plus.

It's really one of those IEM that nail both fun engaging dynamic musicality with impressive technicalities of well tuned planar.

And the standout being its over sized soundstage make it unique in planar realm since only other one with impressive soundstage is the 7HZ Dioko which is less well balanced, have inferior technicalities, thinner harsher timbre and wonky thin bass.

At early birds price, the Dioko was ultimate sound value bargain, but even at now 140$ price it's among the best money can get.

Very Highly Recommended!

I’m so happy to have the opportunity to try the heir to the Hidizs MP145.
However, the review will still be 100% honest and in no way biased.
I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.
So I’m not going to use super technical words to review it, but I will do my best to describe it.

Hidizs MP145 Packaging:​

The Hidizs MP145 packaging is similar to all the Hidizs packaging, a high-quality box with all the accessories you need and a good quality cable included.

Inside, we find various accessories, such as:

• Storage bag
• 4.4MM Cable (3.5MM Available )
• 9 pairs of tips
• 3 pairs of tuning nozzles
• Manual and Warranty

Hidizs MP145 Design/Build quality:​

As you can imagine, the design of Hidizs MP145 is inspired by whales. It resembles both the tail fin and the texture of the whale’s skin. The shell has a truly absurd quality, in die-cast aluminum and some CNC machining, it is one of the best shells ever seen. It has several ventilation openings on the back, referred to as breathing holes, which act as a sort of bass reflex and pressure release.


I have to admit that it is not the lightest IEM, but fortunately, thanks to the shape of the shell and the cable hook, it efficiently discharges its weight uniformly on the ear without causing any discomfort.
The cable with high-purity single-crystal oxygen-free copper silver-plated wire, as always, appears to be of excellent quality and, fortunately, of the right thickness so as not to weigh too much.
As usual, my photos will best describe the overall quality of the product.

Hidizs MP145 Comfort/Fit:​

At first glance, even the tonnage seems like a whale, but I can assure you that the shape of the shell allows for a perfect fit. Moreover, you have 3 different types of tips, so you will surely find the one that fits you the most. They are slightly heavier than average, but once worn, they have total comfort. The thing that amazed me was the practically total isolation from the outside. It’s like wearing two earplugs.

Hidizs MP145 Initial sound impression:​

Since I’ve only used the KZ PR2 and the HE400SE, I can’t claim to be an expert on planar IEMS, but the MP145 has a specially made “FAST” symmetrical big planar magnetic driver that has an unmistakably warm tone!

The fast and precise bass is undoubtedly surprisingly powerful (I almost mistake it for massive DD), but there is also the typical crazy planar detail and soundstage. Both the mids and highs are clear, exact, and without any weaknesses. Absolutely amazing!

I regret to inform you that the KZ PR2 V2 I have been listening to up until recently is ridiculous garbage in comparison.

I’m not listing the tracks because they’re too many, but the MP145 is suitable for everything! My impressions are given using just the original accessories.

They sounded good right out of the box, and after 100 hours, I confirmed all first impressions. The tuning is Harman 2019 and therefore V-shaped.

These planars have fast, robust, and deep bass. From what I knew, it was very difficult to achieve such results using a planar in a small shell. It doesn’t sound like you’re listening to small IEMs at all, more like full-size headphones. Having a particularly warm tone and a similar bass, I thought I was listening to a particularly large DD; however, its 14.5mm “FAST” planar driver is felt in all its grandeur.

As for the mids, they are slightly recessed but totally pleasant and present, while the highs are rich in detail and typical planar air. There’s an insane amount of macro and micro-detail that leaves you satisfied with every volume and track.

Bass​

In the Hidizs MP145, you don’t need a high volume to hear the low frequencies. On my EPZ TP30, at the first volume level, you can hear everything perfectly. The bass hits hard right off the bat, all the way up to full volume, where you can directly feel the heaviness in your ear canal. A low frequency response that embarrasses many sets! In Billie Eilish’s tracks, the bass envelops you in 360 degrees.

Mids​

The mids are obviously recessed, but not too much. Despite everything, the amount of detail is impressive, and the voices are natural and silky. Nothing is missing, and even the instruments play perfectly as they should.

Treble​

The highs are full of macro and micro details, and there is a remarkable airiness. The extension is smooth and free from annoying peaks; even the most sensitive will be able to enjoy this set without problems.

Soundstage and Imaging:​

The soundstage is spatial! It is not exaggeratedly large as to be unnatural, but I would say it is the right size. The image is practically holographic; everything is properly separated, and songs that seemed flat before now also have depth and directionality from instruments and vocals. probably, in terms of Soundstage and image, the best set in my collection. Planar drivers in this field are hard to beat.

Tuning Nozzle:​

As in the latest Hidizs releases, we also find the tuning nozzles in these! Personally, I find it much more practical than tuning switches.

Honestly, the balanced one is fine for 99% of my cases.

The Silver one (treble) increases a little bit in the treble area, slightly reducing the bass. If you are looking for some detail and extra air, this nozzle is probably the most suitable. It also seems to gain something in terms of soundstage.

The Rose gold nozzle (balanced) is absolutely my favorite of all. First of all, you hear it as Hidizs conceived it. In my opinion, you have the best of all frequencies.

Red (bass) The red nozzle increases the perception of bass by reducing high frequencies. Honestly, the set already has a warm timbre, so I found it less interesting than the others. But if you are a basshead, you will appreciate it too.

Hidizs MP145 Comparison:​

Vs HE400SE (review incoming)




I’ve just received the Hifiman HE400SE, just in time to give a quick impression and comparison with the MP145.

First of all, the Hifimans are open-back, so external noises enter more easily. In terms of driveability, they are more difficult, and you will probably need to buy a balanced cable (which in the MP145 you can choose at the time of purchase). Having said that, the MP145 is even superior in terms of sound quality; it certainly has a warmer timbre and much more full-bodied bass, and in terms of details, I believe it offers something more than the HE400SE. Both are very good, but personally, I prefer the MP145. What’s more surprising is how Hidizs managed to get a sound comparable/superior to a full-size planar.

A first impression given using an SE cable without having carried out an adequate burn-in may not reflect the reality of the facts.


Vs MS5



I personally think they even outperform the MS5 at 360 degrees. It is hard to believe given the price of the MS5, which is excellent, but sometimes the sound could seem compressed or congested, which on the MP145 does not happen even on really complex tracks. The timbre of the MS5 is brighter but also more tiring after prolonged listening.

Vs MS3​

The MS3 is the one that comes closest to the MP145, but the planar wins hands down here too. The speed and accuracy of the planar found on the MP145 flawlessly reproduce every frequency. The basses are more full-bodied and thick, but the speed is always absurd. They are both excellent headphones, but if I had to choose, I would go with my eyes closed on the MP145.


Vs DZ4




Although I definitely liked the Letshuoer DZ4, I have to admit that they lost miserably against the MP145. It starts with the build quality and ends with the overall performance. With an inaccurate image and inferior soundstage, the basses are not even comparable, but above all, the quality of details is missing as soon as you wear them. It doesn’t make much sense to compare DDs with planars, but the price is very close.


Conclusion:


I miss the comparison with the Letshuoer S12 pro, of which I am waiting for delivery. I hope they arrive soon so I can add the comparison.


In my modest collection are currently the IEMs that have surprised me the most from every point of view. Let’s start with the build quality of the Hidizs, which, in my humble opinion, improves set after set. Here we have a totally aluminum shell with an almost perfect assembly. The sound is truly exceptional in my opinion. I’m not a planar expert, but comparing myself with experts, we had the same sensations. If I consider that the Super early bird price is only 109 USD (now 139 USD on Kickstarter), everything is even more fantastic!

The MP145 shells are solid and well built, they are however on the larger size, so small ears should take note. I found comfort for me above average, and isolation was very good. The accessories were well made, but I really would have liked a case for such a nice-looking IEM. It should be noted that these like a little more power than an average BA or DD IEM. I would recommend a decent dongle-DAC at the minimum.

Personal assessment and opinion: The MP145 is large and made entirely of metal. For me the shape and roundness of the back are comfortable, I love the cable but wish it was modular. Besides the pouch for storage, the unboxing was good, and everything points that this is a premium product.

ifi Gryphon, ifi UNO, Dethonray SG1, Questyle M15, Fosi audio DS2, Hidizs XO, Burson Funk, Periodic Neon, TempoTec V6, Surfans F35, ifi GoPod, and TRI TK-2

Sound Impressions:
The Hidizs MP145 has a unique big Planar sound.

Bass:
The Bass on the MP145 is very well rounded and balanced sounding. There is good speed with both lower and upper Bass and excellent texture. While the Bass does have a fast decay it still manages to be fun without too much overstepping into the Mids.

Mids:
The Midrange is rich and has good note weight, both male and female sound lively and full bodied but not overly thick, the MP145 does have a little recession to the lower mids but it is overshadowed by the wonderful vocal details and transparency.

Treble:
The Highs present with a good energy, they are open and airy with just the right amount of sparkle. While lower treble and upper mids have a slight heat to them this is not always present and not an issue with normal volume and decent recordings. I found the highs to be well extended with control and details.

Soundstage:
The MP145 Has a magnificently wide stage, it does have good depth and height as well. The overall performance has precise location and layering with me being able to hear each separate instrument clearly. The soundstage doesn't suffer any penalties from busy or boosted lower end songs.

Afterthoughts:
The Hidizs MP145 is one of those IEM like the S12 destined to be on everyone's list. It has the right combination of an accurate and detailed but never boring sound. The design is cool, and it is made extremely well.

HIDIZS MP145 (2023) + (2024 vers.)

Hidizs BEST?

Pros:
+ One of the more natural sounding planar beside the S15.
+ Great detail handling. Highly resolving.
+ Good level of vocal transparency despite slightly recessed.
+ Great sound-stage recreation (space/layering/separation)
+ Overall dynamics is great, excellent transient and speed.
+ Impressive price: performance value.
+ Generously accessorised.
+ 2024 version is better tuned which addresses some of its flaws but with a different trade-off.

Cons:
- Planar timbre is still present: - A hint of lower to mid treble sharpness. LESSEN on 2024 vers.
- Lacks a hint of reverb overtone on vocal & instruments. Due to its quick-ish decay and shorter sustain.
- Bass response can sound a tad too boomy. Can be mitigate with aftermarket tips. LESSEN on 2024 vers.
- There's a slight dryness on vocal transient in trade for better transparency. LESSEN on 2024 vers.
- Can get fatiguing on longer session, especially with brighter dacs or higher listening volumes.
- Planar timbre is still present. A slight sharpness on low-mid treble region.
- A whiff of sibilant tendencies. LESSEN on 2024 vers.
- Best to pair with warmer bass and with treble roll-off source.
- Potential fit issue ; Chonky shell
- Seems to have a phantom revise? 2024 version is slightly different than 1st batch of 2023 from my memory.

Hidizs MP145 (2024 Revised) 4 ★★★★ ​

​

​

SOUND-SIGNATURE:
To my ears, it falls within the purview of v-shape territory that is tilted towards the bass over the treble region. It is more mid-bass oriented while the treble has slightly more emphasis on lower to mid-treble region. The mid-range is the least forward within tri-frequency range but does not suffer from overly recession. The planar timbre is seeming less with great technical performance to carry it’s intended tuning.

BASS/LOW-END
For people who are ultra-conservative about a dynamic-driver bass timbre will have to lower their expectations. This is perhaps MP145’s greatest weakness. The tonal temperature is not cold but closer to neutral with a smidge of warmth on the low-end. The bassline is certainly fast and punchy but the impact is rather soft and could use a bit more control in its demeanour. The overall presentation is rather one-dimensional, lacking layering and separation between bass elements which affect its bassline definition. Having said that, the mid-bass still offers adequate sense of thump, kick and slam for as long as you don’t expect a visceral attack coming from it. Whereas, the sub-bass still provide a good amount of rumbling sensation despite the noticeable roll-off. The decay rate is fast but not instantaneously quick. The ghetto-bass replay is sufficiently good. It is quite capable in capturing elements of echo or reverb in your music unlike, some of its counterpart. However, on some instances, specifically on higher volume, the bass can come across rather boomy which can be quite distracting. Regardless of the flaws, this level of bass performance may not satisfy a true bass connoisseur but truth be told, it should be decent enough for most listeners.

MID-RANGE/VOCAL
As the tuning suggest, if mid-range/vocal reproduction is your priority, then this is not it. Having said that, it is not overly recessed in its presentation. It still proffers good level of transparency with pleasing tonality. The vocals came across least coloured yet natural in tone. It strikes good balance between euphony and clarity. In general, the vocals and instrument sounded crisp with ever so slightly quick decay plus adequate note weight. It can reveal vocal texture, breath and reverb brilliantly. The vocals never seem to lack in energy be it male or female. And there has not been one shouty moment throughout the test. However, for people who prefer lusher or fuller-bodied mid-range might find them to be lacking. Speaking of naturalness of vocal transient, on some cases, male vocals can sound a tad thin and gritty meanwhile female vocals tend to suffer from a slight sibilance issue but bearable still [YMMV].

TREBLE/ HIGHS
Right of the bat, timbre-wise, it is simply one of the more natural treble-response in planar market. It’s got great extension with good amount of air presence with minimal peaks and troughs. It does not come across as overly bright let alone dark in its tonality. Unlike some of its rival, any metallic sheen, sharpness or haze is kept to a negligible degree. It is ever so close to zero but it isn’t zero. Note definition is crisp with natural decay and extension. And the reproduction of synthetic noise such electronics performs equally as good if not better than analogue instrument. As good as it is, it is not a without flaw. Other the slight sibilance issue, elements of lower to mid-treble region can sound a bit hot or too loud depending on your ear’s sensitivity and volume loudness. People whom sensitive to treble might want to take note. With that out of the way, there is really not much to complaint about in terms of treble performance. Despite my criticism, it is definitely one the finer planar treble to date.

TECHNICAL PERFORMANCE:
- The stage-recreation is it’s forte. It sounds quite open and spacious. It plays more width than height with believable depth. The overall presentation is far from sounding intimate. The elements of bass and treble will come across more forward in the mix with the mid-range/vocals been push back ever so slightly. Despite that, the vocalist still appears centered surrounded by images of instrument. The stereo-imaging is exceptionally well. The instrument spatial cues are quite sharp and precise in its conduct, thanks to its spacious stage and blacker background. All and all, the transition of sound between channels are rather well articulate.

- Instrument separation and layering are great. The vocals are very well separated from the rest of the background instruments. The spaces between each element of sound have more gap than usual. And it is done with great consistency even on extreme passages.

- The detail handling is to be expected from a planar. It is very capable on the grand scheme of things.. This level of performance punches way above its asking price. The bass detailing might not be up to par but anything above that region is very well executed.

- The overall timbre is rather natural but not the most realistic among the planar, it is very crisp on the attack but not as impactful as you would want. The decay often falls on the quicker side of the tempo which can take away some of that trailing end of note definition. The note weight is by no means lacking but could use a bit more heft for added presence. It’s ability to retrieve reverb effect is pretty acceptable for the most part which is to say it's not lacking.

- The driver potential is great at its core. The sound it produced never seems to get distorted. It managed to deliver a cohesive and harmonious sound with very little timbre contrast. And there is no driver-flex issue as well.

Tuning Nozzle Options :
Red Nozzle : Nerfing the treble brilliance for added bass presence.
Silver Nozzle : Too much treble, give rise to sibilance with over the top lower-mid treble energy.
Rose-Gold Nozzle : The best tonal balance. Minimize bass and treble issue. [My Personal Pick]

" SYNERGY, VOL.SCALING, POTENTIAL TWEAKS "

- DAC/AMP: I find the MP145 to be not as source picky as some its main rival. Still to bring the best out of it, I’d suggest to pair it with something that has more mid-centric tuning, snappy and tight bassline that isn’t too bright on the treble or something that offers better note-weight and slower decay would really synergy well with the MP145. It is quite efficient when it comes to power to drive. It does not need a high amplification to achieve good listening volume but it will scale with better AMP like most other planar do.

- EARTIPS: It is best to use a wider bore tip just to reduce the bass quantity giving the mid-range and treble more room to breathe. Wider bore mostly helps in mitigating that boominess and sibilance issues on higher volume. Since nozzle the lip has a bigger diameter than usual, be sure to use the tips that has the right diameter to avoid damaging stem of your ear-tip’s.

- CABLE: The stock cable sound and behave pretty nicely. There is no need to upgrade the cable. If you were to replace, do not buy a heavy thick cable or else that chonky shell can leave an unnecessary pressure on your ears. It is quite sensitive to cable swap as well which is great. #Snakeoilgang can apply their knowledge for possible potential tweaks.

- VOLUME SCALING: On lower volume, it sounds quite dull and inspiring. On very high volume, the bass starts too sound too boomy and the lower to mid treble energy tends to cause fatigue. So, it is best to listen it at medium-loud volume.

[UPDATE][2024.01.31] THIS IS MY 2ND TOUR OF THE MP145
Based on my memory using the same setup & test-track) It is slightly different compared to the 1st set I've assessed.
The 2nd Unit : (Please do take with a grain of salt) It is now sounds
1) Going for more balance and analytical approach.
2) The bass has better control but still sounds a tad boomy as the mid-bass has too much presence and lingers too a tad too long.
3) The treble sounds less hot and has smoother response but sounds slightly brighter giving a sharper low to mid treble definition.
4) Due to added brightness, the vocal came across a tad sharper or too airy.
5) Due to the smoother treble response, It has greater tolerance on sibilance.
6) Reverb overtone is still not its strongest point.
7) Warmer/Fuller sound-chain is still required with the newer version.
8) A smidge of planar timbre AKA sharpness/metallic sheen especially with neutral/bright DAC/AMP.

When everything is set and done, the MP145 does hold great potential, capable of knocking the doors of higher price bracket. But in reality, how good is it?

IN-DEPTH COMPARISON


vs 7hz Timeless (feat Kinera Leyding)

Overall Presentation:
- The Timeless also carries the same sort of v-shape kind of tuning but it sounds slightly more intimate and less wide in staging. The elements of bass,mids and treble strike better balance in its response. The MP145 mid-bass, lower-upper treble can get slightly out of hand depending on tracks or volume loudness.

Bass :
- Right of the bat, the Timeless bass performance is superior to the MP145. It handles its bass elements with greater finesse. The presence is more intimate in the mix with warmer tonality. The sub-subbass extends lower with better rumbling texture and tremor. The mid-bass offers more satisfying kick, slam, punch and thump.
- The bass attack is just more impactful. It hits deeper and a tad more visceral in its demeanour. The decay is more accurate (slower & longer), nigh perfect for a planar driver. The bass instruments are just better defined. Every note-hit is sharper with heftier note weight, making MP145’s bass note sounds blunted by comparison. The bass layering is simply superior on the Timeless. The sub-bass and mid/upper bass just have better contrast. The ghetto bass replay is much more impressive here as well. The rebound rate is more realistic. The bass response on the Timeless is felt more than heard versus the MP145.
- The overall bassline on the Timeless is closer to a dynamic-driver timbre.
- One bassy songs, the MP145 will sound more bass dominant. The mid-bass can be abit overpowering sometimes, whereas the Timeless sounds more balance from sub to mid/upper bass region regardless of volume loudness.

Mid-range/Vocals:
- They both inherited some kind of a v-shape tuning hence any elements that lies in this region will come across slightly pushed back within the mix. However, due to the more intimate nature of the Timeless, it makes vocals and instruments sounds less recess than the MP145.
- The MP145 has slightly better transient here, the initial hit of note just sounds crispier and more incisive on the attack. The MP145 has the upper hand on rendering its vocal texture despite sounded slightly more recess.
- However, the Timeless provide its mid-range with more realistic decay (slower) and extension (longer). The vocals and instrument sounded fuller with more body and weight on its replay, thanks to its warmer and thicker colouration coming from its lower harmonics. To my ears the timbre is euphonically sweeter on the Timeless. Instrument like pianos, violin, strings, flute are more satisfying to listen too.
- The MP145 male vocal can sound a tad thin and sharp by comparison. Thankfully, female vocal has ample of energy with believable voice range and are equally as good on both sets. They do trade blows with plus, minus, here and there. But If I were to nit-pick, the female vocals on the MP145 has lower tolerance on tracks that has sibilance artifact which is worth noting.

Treble:
- The Timeless sounds slightly less bright in tone, the treble presence and extension from lower to high treble is much better executed in terms of energy dispersion. The Timeless however, sounds more open and airier up top. And for some reason, the treble sounded more relax than the MP145.
- One of the reasons is due to its bassline doings. The warmer hues coming from its low-end truly helps in easing out its treble energy, giving listeners a more pleasant experience in the long run.
- The other reason being is the MP145 seems to have slightly more emphasis/energy on lower to mid treble. As a result, any elements coming that region can sound a tad too sharp or too loud depending on tracks which can get quite fatiguing on higher volume.
- Cymbal-strike and hi-hats sounds natural and inoffensive on both of them. The MP145 may sounds crispier but the Timeless plays with better note-weight and decay. And the same true can be said with its drum-hits extension as well.
- Synthetic noise or electronics replay are a toss-up between the two. Depending on tracks, they could out-do each other.
- The treble on response on the MP145 may sound cleaner in a sense that it has slightly less haze, micro-grain or any sort of harshness nature.
- Overall, the treble performance goes to the Timeless. It sounds more unique to my ears. It has slightly better definition. The treble element is dispersed in a more correct manner without giving unnecessary energy to lower/mid treble which can affect the naturalness and refinement of sound.

Technical Aspect:
- The stage rendering on the MP145 blows the Timeless out of the park. It sounds wider, taller and have significantly more depth which is severely lacking in the Timeless.
- The spaciousness of MP145’s stage allows each element of sounds to have greater sense of space or gap between them which improve layering and separation. When your music gets busy, elements though are separated can sound rather cramp on the Timeless thanks to that peculiar stage. The MP145 seems to have a blacker background as well which helps greatly in separating the sound.
- When it comes to instrument timbre, The Timeless is hard to beat. Every note hit just sounds very distinct; Impactful attack, precise decay & extension, great note weight with good reverberation. Among the recent planar, the MP145 managed to get the closest to Timeless’s timbre which is impressive in its own right.
- Dynamic wise it is more skillful to make use the loud and soft of instruments which adds more emotions to musical score. Micro-detail (non-musical detail/artifacts) on the Timeless is slightly superior as well. It is more capable of retrieving those element as well such as the breath of the singer, finger sliding on the guitar, twang on strings, note page being turned, piano paddling, echoes in the room/studio, microphone noise and the list goes on. Those artifacts are without a doubt, sound clearer on the Timeless which says a lot about its resolving prowess. And the MP145 is close behind.
- Both scales significant well with better DAC/AMP. The Timeless sounds brilliantly on low volume. And sounds best on mid-high volume. The volume scaling on the MP145 is trickier, very song dependant. Not so great on lower volume. Best performs at mid-volume.
- Timeless is more comfortable to wear for my ears. It almost felt non-existent when plugged into my ears. Whereas, with the MP145, you do notice it’s chonky shells and can exhibit unwanted pressure with the wrong eartips. Despite that it is still comfortably light to wear.

So which one should you to pick?

The difference is not night and day, they’re closer than you might think in terms of overall performance. Notice that the words like “slightly, abit, a tad, a little” got repeated multiple of times just to highlight the gap between them.

If you’re stage fanatic which priorities spatial cues, imaging, layering and separation with slightly better vocal transparency, the MP145 is definitely a good buy. But if you prefer slightly less energetic bass/treble presence, more realistic instrument timbre with stronger micro-detail retrieval & dynamics, the Timeless (+ Kinera Leyding, A MUST HAVE) is the best buy here. End of story.

FINAL THOUGHTS
Just before I send it back to the rightful owner, I gave it another long listen. My stand on its pros and cons still remained. And I still love the 7hz Timeless x Kinera Leyding at tad more. But one thing for sure, the Hidizs MP145 could be an “Endgame or Pause-game” set for people who don’t want to spend no more than 200$ on the pursuit of this hobby. It is technically capable with natural timbre, very likeable tuning and can plays all walks of genre effortlessly. Sure, it is not a flagship killer by any means, but considering Its price performance value is that high, it is a no brainer really. It can simply tail-gating higher price bracket without breaking a sweat. It is that good. Especially, when you can have one now at a huge discount on kickstarters.com. Even at full price, I still think it is well worth it. Regardless of my preference, it has achieved remarkably well in what it’s trying to be. I would totally recommend to have a look at the MP145 if you’re after this kind of tuning. A very solid product nonetheless. Well done, Hidizs!

Introduction

It was only a matter of time before Hidizs designed IEMS with a magnetic planar driver. In addition to its whale-inspired design, Hidizs has established a partnership with the world's leading charity dedicated to the protection of whales, dolphins and their ocean habitats: Whale and Dolphin Conservation (WDC). With their help, Hidizs has designed the MP145 to incorporate a whale tail on its outer face, as well as rorqual folds. The outer face is divided into three parts with a twelve-layer milling pattern that resembles the tail flukes and pectoral fins of whales. In addition, discreetly integrated into the transition zone of the whale tail fin-shaped panel are two hidden ventilation ports. These vents optimise airflow within the earcup cavity, improving transparency and sound balance.
Internally, the MP145 integrates Hidizs' customised 14.5mm "FAST" ultra-large planar magnetic driver. "FAST" is the name of this driver, it is a symmetrical planar magnetic transducer with a 14.5mm diameter diaphragm and is named after the largest radio telescope on earth. Its magnetic circuit has a precise arrangement of 7+7 N52H magnets, whose magnetic flux is greater than 1 Tesla. As usual for the latest Hidizs models, the MP145 also incorporates 3 pneumatic screw-in sound tuning filters. Together with the meticulously designed vocal, balance and bass tips, the MP145s offer 9 different sound styles.
Indeed, these new Hidizs MP145s hold many surprises, both on the inside and on the outside. But also in their sound, which is precisely tuned to the Harman 2019 target curve. This tuning can be modified thanks to the included filters.
Let's take a closer look at what this new magnetic planar model called Hidizs MP145 has to offer.

Packaging

Hidizs is being restrained in the presentation of its latest creations and the size of the packaging is medium. It repeats black for the background and gold for the lettering. The size of the box is 155x96x55mm. The brand logo is in the top left corner, the Hi-Res logo on the top right. Underneath is an icon representing the magnetic planar driver used in this model. In the centre of the box is a real photo of both capsules with their cable. Below is the model name justified to the left and at the bottom, in two columns, the different features of the model in 3 languages, including English. On the back side you can read all the specifications in white letters and in these 3 languages. The contents of the package are also specified:

• The two Hidizs MP145 capsules.
• 3 pairs of tuning filters.
• One storage bag.
• 3 pairs of SxMxL size tips for vocal tuning.
• 3 pairs of tips size SxMxL for balanced tuning.
• 3 pairs of tip sizes SxMxL for bass tuning.
• 1 user manual.
• 1 warranty card.

After removing the outer cardboard, a rigid plastic box with a micro rough texture appears. The logo, brand name and slogan are inscribed in the centre. Under the lid, the capsules are revealed inside a foam mould lined with black cardboard. Its outer side is covered with a transparent protective film. Underneath is a box, also made of black cardboard, with the brand's logo in the centre and a description of the model at the bottom, all in holographic ink. Behind this first layer are the 9 pairs of tips arranged according to their characteristics in a mould that indicates both the size and the type of tips they are. On this layer you can see the user manual, the warranty card and the quality certificate. Inside the box is the storage bag, in black leather with the logo in the centre. Inside is the cable and a small transparent box containing 2 pairs of tuning filters, the third pair is installed in the capsules. It should be noted that the methacrylate box is screwed open and not snapped open, you have to turn the two pieces together and the box will open. Inside there is also a kind of desiccant sponge.
It is appreciated that the presentation is neither ostentatious nor overly large. The size is adequate and the presentation is elegant, repeating patterns of black and gold as on other occasions. The idea of the box containing the filters and the foam base that houses the tips is appreciated. On the other hand, being a product of this category, I miss a more rigid carrying case than a leather bag.



Construction and Design

The Hidizs website is quite eloquent and descriptive. In the case of the MP145, the presentation page is extensive and discusses every external and internal detail of its manufacture. It is clear that the MP145 has a whale-based inspiration, the result of their collaboration with the WDC organisation. The outer face has a raised Y-shaped part. This is actually the tail fin of a whale. The adjoining parts on each side of the fin form a staggered pattern, a twelve-layer milling pattern, also inspired by the pectoral fins of whales. On both sides of the whale tail there are two ventilation slots. The shape of the capsule is slightly elongated and has 7 faces, 4 on the bottom and 3 on the top, if you take the top where the cable connection is. The part near the nozzles ends in a slightly tapered arrow shape. The 2Pin 0.78mm connection is completely shallow and the plastic part containing the contacts is integrated inside the capsule. Of course, the connectors are gold-plated.
The inner face grows with a regular slope from the connector area towards the nozzles. The surface is curved on both sides of the sloping line. On it and near the connector, the name of the model can be read and towards the inside, there is a mole with the lettering of the channel. The ink used is dark grey. Near the nozzle but offset from the slanted line is a hole. The nozzle is cylindrical and ends with a thread to secure the filters. There are 3 filters, the standard filter is the Balanced / Rose Gold filter. The high-frequency filter is grey (Quiet Silver) and the red filter (Charm Red) enhances the low frequencies. Their diameter is 6.9mm. The total length of the nozzles with filters is slightly more than 5mm.
The material used for the capsules is aviation aluminium alloy.
The capsules are available in three colours, grey, light grey and dark blue.
The cable can be chosen in two terminations, SE 3.5mm and BAL 4.4mm. Once again, I am pleased that Hidizs is now offering this option as standard, without the need to buy an additional cable. The sleeve of the 4.4mm plug is cylindrical, regular, very smooth, has a golden ring near the cable exit and on it you can read the brand name. The cable consists of 4 strands of 6N silver-plated monocrystalline copper wire. The splitter piece is simple, another small, smooth, shiny metallic cylinder. The pin continues this minimalist style and is a simple metal ring in the same pattern. The cables have over-ear guides and the connector sleeves are two cylinders to match the rest of the metal parts of the cable, which have two grooved and painted rings to indicate the channel. The two pins protrude from a transparent plastic disc and are gold-plated. The 4.4mm plug is gold-plated and protected by a translucent plastic sleeve.
The capsules are slightly large and elongated. The finish is very good and the design is distinctive, bearing little resemblance to other models. There is a strong effort to be original in this model and the combination of whale inspiration is noticeable. The weight is 19g per capsule.
The cable has a shiny silver plating, each strand is of good thickness, forming a cable of medium thickness, attractive enough and of good quality not to have to change it. It is also comfortable, has good flexibility and the balanced 4.4mm termination makes me forget to look for a replacement cable. Excellent.



Adjustment and Ergonomics

As mentioned, the shape of the Hidizs MP145 is unusual and its size tends to be large. Rather, the elongated shape of the capsules does not compromise ergonomics. The slight arrow shape, where the tip part coincides with the position of the mouthpieces, favours positioning and placement. Fortunately, the inner shape of the capsules is flat, rounded and has a very soft, sandy micro-texture. The other end of the capsules stretches beyond the pinna. In my ears the integration is very good. With the right tips, the capsules float in the pinna and do not rub against any part of the ear, except for the bottom, where they sit lightly. The mouthpieces are not very projected but have a good angle and I don't find any fault in their placement, the fit being firm and durable. It is true that the capsule can rotate, but its optimum fit point is at the end of its travel, as further rotation is not possible. The whale tail shape and the folds make it easy for the fingers to adjust the IEMS in the ears. With a shallow or light insertion the level of sound insulation can be high, as long as suitable tips are found. As usual, I have used my large foam-filled tips that I make at home and the fit and ergonomics have been quite good. But I don't dispute that the size, shape and perhaps also the weight might be controversial for other people.
Finally, the position of the over-ear cable and the fit of the capsules does not feel compromised by their combination. Thus, the cable does not disturb or negatively affect the fit of the capsules or rub uncomfortably on the ears. At least, not in my case.



Sound

Profile

I have been lucky enough to try several planar IEMS before I got to the MP145 and it is true that the sound coming from this particular driver has a characteristic and special sound. But it also adapts to a curve that can be more or less similar. The good thing with the MP145 is that there are 3 filters to tune this curve and bring it even closer to our preferences. In addition, there are 3 types of silicone tips that allow you to tilt the sound a bit more. In total there are 9 different tunings. In my case, most of the standard tips don't work for me. I have unusually wide ear canals and can only use very large tips. So most of the standard tips don't work for me because they barely hold in my ears. But I found a solution, to fill with foam a certain tip whose canal is quite wide. This type of tip is similar to the Simbio tips, but a bit bigger. It is true that this limits the tuning produced by the tips, but it reduces the choice of the best tip for my anatomy to 95% of the cases. It is for this reason that I have not been able to test the tuning tips that come with the MP145.
On the other hand, as I mentioned when I reviewed the LetShuoer S12s, I don't have a target or preference curve in Squig.link. But it is true that I do lean towards a strong and powerful low end, a full midrange and a treble that slightly exceeds softness, with some personality. In fact, I like all bands to be well represented, with a preference for lows and mids. I also lean towards an analytical sound. The curve of the S12s was very much in line with my preferences, but their sound is generally soft and not as detailed as I like. What are the MP145s like? Well, the curve between the two bears a lot of resemblance to the standard Balanced filter. The curve of the Hidizs is a bit more balanced and rounded. It's like a polished version of that one. The sense of fullness and wall of sound is present, but I feel there is a hint more analytical and descriptive ability, but without the brightness being predominant. The truth is that this planar driver gets that great representation in all the bands that I look for.
The profile could be categorised as U-shaped or soft w. The inclination towards the sub-bass is linear, without being predominant. But there is a good extension towards the midrange. The transition into the mids is smooth, generating a body and density in the initial zone of the midrange. The rise into the upper-midrange is subtle and once there it is maintained into the treble with a fair amount of linearity, adding explicit and quite extended upper range, but without losing the smoothness. If you want a little more spice in this transition zone between mid-high and first treble, just choose the treble filter to add that extra sparkle. If, on the other hand, you are looking for a slight bass boost and a smoother mid-high, but without losing sight of the treble, then the bass filter is the one for you.
The use of the red bass filters limits the volume slightly and orients the sound towards a darker, denser profile. Voices lose some sparkle, both female and male. The bass gains in prominence, but some of the representative grace of the balanced curve is lost, such as the great balance between the three bands.
The use of silver treble filters subtly softens the lows and excites the mid-highs and first highs, adding more life and presence in this area. Male voices return to naturalness, while female voices become more seasoned and vivid. The highs have more presence in the mix and the details gain prominence. The sound becomes more splashy, but also more intense in that more sensitive range. This can be a double-edged sword, the sound becomes somewhat more analytical and descriptive, but also more penetrating, becoming more fatiguing.
The gold filter offers the most balanced sound and manages to balance that mid-high and high range in a sweeter point that allows for long hours of use, without losing the descriptive ability, but softening it to a much more comfortable point.

The description of the bands has been made with the rose gold filter balanced.



Bass

The planar bass is particularly characteristic. If the definition of natural bass is described and executed with a good dynamic driver, the planar bass adds a point of technique and speed that normal dynamic drivers do not achieve. The sonority is slightly different, dynamic drivers move more air and can generate a point of greater power and visceral capability. However, the first test I performed with the MP145s was my usual pure tone test. Here I could see that the MP145s decay in the more extreme range and lack a little more presence from 20Hz to 35Hz. From 40Hz onwards is when the driver emancipates itself and demonstrates an improved ability. In that initial range there is subtle colouring, although the behaviour is realistic, but not as sensory. From 40Hz onwards the driver improves in all aspects, sounding natural, punchy and fast. When you get back to the real music this behaviour translates into a dense, but fast punch. The decay is fast and there is hardly a trace of bass in the room. The beauty of this behaviour is the sense of space it is able to generate: the bass opens up the environment and makes it deep, when it disappears that space is filled with the rest of the music and the details remain prominent. It may sound like an inappropriate but eloquent comparison: the bass behaves like a bomb that clears the way.
As I say, they don't move as much air, but their punch has power and presence. Bass lovers won't be able to overlook that punch and energy level. And that's where I find myself, enjoying them.
With fast transients, the bass limits the boominess without losing the natural, elastic feel of fat, thick bass drums. This is a vitaminised band, with many hours in the gym. There is muscle, a tight bass capable of layering with ease, following complex, unfiltered lines without distortion. It's everything you look for in a bass range. If you add power, punch, richness and, above all, naturalness to all the technical skills, precision, resolution and definition, it becomes an exquisite range, and that's what the MP145s represent.



Mids

Despite the representative density in the mids, the relatively slow, but subtly accentuated drop in the low end generates quite full, but not foreground-sounding male voices. For example, the strings, drums and bass are subtly in front. Despite this, their timbre is quite adequate and realistic, more so when it comes to planar. We are talking about a complex and effective representation, which has a good base and whose details are presented in the right measure. Its complexion is rich and almost exuberant. The pity is that they are sometimes subtly distanced. A slightly closer presence would have made them absolute and excellent protagonists. As I say, in this first half I find more prominence for the instruments, except in those songs where the vocal presence is prominent. It is, then, where all that descriptive, precise, rich and completely musical power is shown in the male voices. I have to refer again to the concept of mid-range musicality. The blend of instruments and voices is very good, the level of resolution of the driver offers a very extensive palette of notes, really separated and precise. The transients generate a very accentuated dynamism and all the sounds are appreciated individually, but put together in a very harmonious and... musical way.
The female voices are stellar, the true protagonists of the mid-range, though fully supported by the rest of the instruments. The sibilance with the gold filter is controlled and the treble tuning adds the necessary richness and sparkle to bring the timbre up to a reference standard, halfway between softness and sparkle, harbouring the best of both worlds.
As I have already mentioned, the instrumentation is quite prominent and alternates its major presence between male and female voices. This virtue is determined by the Hidizs MP145's great capacity for recreation, a semi-analytical and very descriptive character. Also evident is the technical skill and the level of resolution so broad as to be explicit in many details, while maintaining musicality. In the background, the expressiveness of the music is high, but its presentation remains simple, because it does not stun, because it is elegant, it is harmonious, it is evident, it is transparent and it is precise. And, returning to the mixture, to the conjunction of voices and instruments, to the overall music, the mutual benefit, their conjunction and symbiosis is obvious, because there is no overlapping. The elements are unique and differential, the notes bring out their individuality and the music is the winner.



Treble

One thing I like about the planar treble is its linearity and extension. The representative level of the MP145's high end is high, but controlled with the Rose Gold filter. Perhaps, with this filter, some may feel that it lacks a little more sparkle, not quite as crisp as you might expect. But with the Quiet Silver filter this point is improved. In my opinion I think it is sufficient, even in energy and presence. However, the balanced filter becomes delicious as the hours go by, because of that mix of smoothness, balance and naturalness it possesses, without losing sight of its great informative level. That is why I think the ratio between length and presence is very good. The great advantage remains the level of resolution and definition, keeping the sibilance under control, adopting a relatively soft, but effective and expressive manifestation of the high notes.
The great linearity of the treble offers a more appropriate timbre, with no hollowness, no over-excited highlights and no control drop. This homogeneity gives it an extended and sustained energy, but expressed in a balanced way that provides a much appreciated naturalness. As usual, the air zone feels a little less accentuated, but its impact on the sound is still quite noticeable.



Soundstage, Separation

The large representation of the MP145s on all three bands gives them a wall-of-sound feel, which is also characteristic of other planar models. But one of the differences that can be felt in this model is produced by the ventilation holes on the outer side. With them, the impression of openness of the sound is increased. The characteristic density seems to be relieved, the scene decompresses and expands, becoming more volatile, extensive and vaporous. In the same way, the separation is more evident, while gaining in clarity and transparency, but also in height. In this way, the scene appears wide, broad, quite deep, 180 degrees are clearly exceeded and the music is able to surround the head, but without offering a sensation outside it that disperses the sound in an unrealistic way. No, the music still maintains its grip, offering a body that is large and full, but not as dense or impenetrable as in other planars. The sense of air is higher than the competition, while positioning remains fairly tight. The high level of definition, resolution, together with the representational capacity, the ability to generate layers, lines and the great power of layering, allows the placement of the elements to be very good, generating an expressive, even eloquent image.
In the end, the MP145s are still not detail monsters, and while the Quiet Silver filter may be more explicit in this regard, there is still a musical softness that allows many nuances to be revealed, but without describing them in detail. I have commented that it is semi-analytical, because it has notable technicalities that manage to reveal a lot of information. But it does not expose it in a surgical way. But, in this way, it gains in musicality and a subtly warm and pleasant quality.



Comparisons

LetShuoer S12

The S12s are perhaps one of the most famous planar IEMS along with the 7Hz Timeless. Although I also own the S12 Pro, I have opted for the original S12s because of their similarity in frequency response, which is more than evident.
On a physical level, the construction is stellar in both models, both are metal, but the size is quite different. For small ears the S12s may be much better, but the shorter length of the nozzles makes them feel shallower, whereas with the MP145s I get a slightly deeper insertion. The S12s are more susceptible to dislodging, although they fit better in the pinna because of their shape. Again, the fault lies in the slightly shorter length of the mouthpieces. Despite the larger size of the MP145s, I feel that their insertion is more durable, but I can't help but think that their larger size may be more critical for some amateurs.
The cable is thick on both models and both have 4.4mm balanced connectors. But I prefer the more manageable cable of the Hidizs. The S12s have two thicker strands that are comparatively stiffer than the 4 thinner strands of the MP145s. The S12s have a hard case which I love, while the MP145s have a leather pouch which is less protective. It's also a bit fair in size. Both come with 9 pairs of tips, while the S12s have foam tips, the Hidizs are accompanied by three types of tips with tuning change capability.
In terms of sensitivity, the S12s are subtly easier to move, requiring less energy to reach the same sound pressure level. Both models are grateful for a powerful source, though.
Although the bass tuning is very similar, the differences are in the performance. I find the bass on the S12s to be somewhat smoother and silkier, while the bass on the MP145s possesses a point of greater punch, energy, but, above all, roughness and texture. Yes, texture is more noticeable in the Hidizs and that makes them more engaging and enjoyable. There is a superior descriptive feel, a more exuberant vibe that makes them a more fun, even addictive choice. The MP145s even seem to possess more depth, volume and expansion in this area. In the pure tone test the behaviour is very similar, it just seems that the MP145s have achieved a slightly better playing stability, a little more control, something that makes for an improvement in the realism of their behaviour and timbre.
In the mid-range, I had commented that the male vocals in the MP145s can lose prominence to the instrumentation in some songs. This effect is also present in the S12s, but is more pronounced in the LetShuoer. However, the big difference is in the mix, in the exposure. The S12s seem flatter and more uniform, while the MP145s are more three-dimensional, more dynamic. The mids seem more excited, more vivid, more exalted, with more sparkle and life. They feel closer and offer the sensation of surrounding the listener within the music, giving an impression of greater volume. In the same vein, the level of clarity, transparency, definition and resolution is more evident in the MP145s. This is noticeable, for example, in female vocals. While the S12s are well represented, in the MP145s they seem fuller, more full-bodied, with a more evident base, a more evident fullness. There is a clearer descriptive level that makes them larger and closer, as well as more discernible, projected, even detached.
In the treble, the sense of refinement is also noticeable in the MP145s, the timbre seems more appropriate and the behaviour seems more natural, even if the tuning is similar.
The S12s present the music more homogeneously, more densely. But there is more space, separation, distance and air in the MP145s. Of course, the scene is larger and more surrounding, but the image is more precise and the elements are easier to locate because they have a more pronounced individual prominence. In the background, the ability to extract simple details is similar, but the complexity and reconstruction of instruments and voices is greater in the MP145s. This gives them a higher level of musical richness, which puts them a step ahead of them.



Conclusion

If there is currently a really attractive, eye-catching, attention-grabbing attribute in the world of IEMS, it is the magnetic planar technology. Every brand wants to have a model with this driver and the race to create their own driver has been going on for some time. Hidizs has now launched its model. This is the MP145, as the name suggests, it uses a 14.5mm magnetic planar driver with a precise arrangement of 7+7 N52H magnets, whose magnetic flux is higher than 1 Tesla. Its design is inspired by whales and collaborates with leading global charity Whale and Dolphin Conservation (WDC). Hidizs has also realised the importance of a great cable as standard and the need for a balanced connection as a purchase option, without the need for additional accessories. But more importantly, within the relative homogeneity of the sound produced by the current planar drivers, the brand wanted to introduce variations to increase the quality of the sound produced by these transducers. In this case, the size of the capsules is larger, something that gives them an image of greater magnitude. On the other hand, the ventilation ports on the outer face help to generate a more airy, expansive, volatile and three-dimensional sound. The level of precision is very high, as is the level of resolution, and the music is more crisp, descriptive, individualised, rich, lush, but also organic, highly dynamic, detached, clean, expressive and with a more natural and accurate sense of timbre than its competition. In addition, as usual in the brand's latest models, three filters have been included to modify a sound profile whose base is the planar reference, as well as 9 pairs of silicone tips that allow a more personalised alteration of the curve, even more customised. With all this, Hidizs has entered the planar IEMS market ahead of other models and placed itself in the front line where the best models are to be found. In short, the Hidizs MP145 has embraced magnetic planar technology and all of the existing background to date to perfect its new model with superior refinement. It's not a huge leap, but it is a noticeable improvement. And that's always a great achievement.

General Info (Packaging/Build/Comfort)
Hidizs is well known for their source namely dongles as well as mini DAP, but looks like they’re trying to up the ante by also tapping into the IEM’s market. They did have several releases previously but they aren’t that well known or widely received. Since the launch of MS5 which is the brand’s flagship, they have been gathering feedback and putting in the work, which can be seen in the subsequent release, which is the MS3. Today i have the MP145 with me, which is a planar IEM, this is the brand’s first planar IEM and the interesting thing is that they are also collaborating with WDC(Whale and Dolphin Conservation) to help raise awareness about the vital roles that whales play in the ocean.

The build quality of the IEM is solid, feels quite hefty and the design inspiration does stem from the whale as well. The IEM’s nozzle is on the large side, so when you are tip rolling, be sure to do it carefully else the tip might rip. Packaging is the usual Hidizs style which looks minimalistic and also presents a premium unboxing experience. The box consist of three types of eartips, the tuning filter/nozzle and also a storage pouch, a solid cable with the termination of your choice either 3.5 or 4.4.

Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far

Sound Impression (Balanced Nozzle)
Upon first listen on MP145, it has got a relatively smooth tuning with plenty of details yet it remains safe sounding and not harsh sounding. Timbre sounds quite natural to my ears with a slight planar timbre if you try hard to listen to it. The nozzle is swappable to either bass or treble nozzle, the default one will be balanced which is the primary sound impression that i’m sharing now

Bass

• Bass is punchy and has good extension to my ears, but not too much to the point where it over power other frequency, adequate amount for the fun factor if you ask me
• Good texture on the bass and the speed is adequate for most genre unless you’re talking about insanely high speed heavy metal, but it is adequate to handle anything you throw at it
• Slipknot’s People = crap is being rendered effortlessly on the MP145, there isn’t a hint of muddyness during the intense drumming opening

Mids

• Mids are very lush to my ears, instruments in this range carries sufficient note weight and doesn’t sound thin at all
• I’d picture the vocal positioning as a few steps away from your face, not recessed nor too intimate, just nice in my opinion
• Female vocal has got decent texture and sweet sounding, evident when playing back Adele’s When We Were Young
• Male vocal is a little lacking in terms of texture, evident in low baritone note, doesn’t sound as thick as it should be, a little more warmth will be great
• Upper mids are never offensive even when you turn up the volume, rather safe for those who are sensitive

Treble

• MP145’s treble is never offensive and yet it doesn’t sound dull and quite musical to my ears, enough energy but never harsh sounding
• Not as revealing in terms of detail retrieval but good enough for the price point, certain instruments can be picked up easily when listening to Hans Zimmer’s Why So Serious
• The treble is never sibilant even when you turn up the volume, or even on some sibilant prone track
• Good amount of air and presence

Soundstage/Imaging

• Soundstage on MP145is quite decent, slightly out of your head and doesn’t sound in your head at all, good width and depth but a little lacking in height
• Imaging is good as well, instruments can be pin-pointed easily and the left and right transition and vice versa is easily noticeable, instrument layering is good, the instruments doesn’t sound muddy and all mashed up in Kid Rock’s Bawitdaba

Driveability

• MP145 is not hard to drive, you will be able to push out decent volume from Macbook Air M2’s 3.5mm jack
• It does scale with better source and amplification as with most planars, in terms of dynamic and more controlled bass

Sound comparison with different nozzles
Bass

• On this nozzle, the low end is slightly lifted, due to the seesaw effect, the treble is tamer and less exciting, this in turn made the overall listening experience a little more laidback with slightly more warmth and body
• Soundstage is slightly smaller imaging capability remains more or less similar
• Still it is nowhere near basshead level, but overall very fun sounding

Treble

• This nozzle will turn the MP145 into a technical beast. Analytical sounding and very detailed and airy
• Bass remains tight but doesn’t punch that hard or rumble compared to balanced and bass nozzle
• Soundstage is good as it is very airy sounding, treble head will enjoy this tuning

Final Thoughts
I have tried several planar IEMs, namely TinHifi’s P1 Max and Letshuoer’s S12, they all have different characteristics and tuning style tailored to different audiences or music libraries. For the case of MP145, I find that it’s safe for me to label it as an all rounder (At least it works well with my library, Metal, Nu Metal, Jazz, Classical, Jpop, Rock, CantoPop). For those who prefer a less prominent bass response, or rather a neutral bass response, you might want to consider other options. I’m not a basshead myself but I do find myself enjoying the slight lift on the low end. Not to mention it is very versatile to change the tuning via the swappable nozzle to add more bass, or treble depending on your preference. For me personally i’ll stick to the balanced nozzle which offers a balance between bass and treble.

MP145 is an easy recommendation to anyone who is thinking to venture into planar iems or even seasoned audiophiles will like MP145 i’m sure.

The MP145 is currently available to pre-order from Kickstarter, the super early bird deals are priced at 109$, at the time of writing, i believe the super early bird is fully backed and the 139$ package is available as of now, still quite a good deal in my opinion
