Hidizs MP143 Review

Intro​

Planar driver IEMs really started to gain popularity when the 7Hz Timeless was released. Since then, many brands have begun creating their own versions. One of my favorites is the Hidizs MP145, which offers great sound along with solid build quality. Recently, Hidizs released the MP143, a more affordable cousin, and many reports suggest it shares a lot of similarities in sound with the MP145.

I’ve spent a good amount of time using both the MP143 and MP145 to really feel the difference between them. In this review, I’ll share my thoughts on the MP143 and what makes it special. Whether you’re a music lover or just want good sound without breaking the bank, I hope this review helps you decide if the MP143 is the right choice for you!

Design​

The Hidizs MP143 Salt comes in a CNC-machined aluminum shell that feels sturdy and well-built, giving it a solidly robust premium feel. My review unit came in the sleek Gun Black finish that gives it an understated yet classy look. The anodized matte finish adds to its appeal, keeping the surface resistant to fingerprints and oils to make it look clean even after extended use.

It’s aluminum, so it has that nice cool-to-the-touch feel, and the finish holds up quite well against all the minor scratches and wear and tear that come along with normal use. The faceplate features a minimalist ridged design, adding some subtle texture but not being too flashy in any way. It is sleek, streamlined, and aesthetic, one that supplies just the right amount of character while remaining subtle and refined.

The Hidizs logo is engraved in a discreet gray tone, adding a nice touch without being too loud. Overall, the design strikes a balance between elegance and functionality, giving the Hidizs MP143 Salt a premium feel.

Comfort & Isolation​

The Hidizs MP143 Salt is an impressively comfortable piece for a metal-bodied IEM, considering it will be in the ears. The lightweight, compact design easily sits within the ear during long listening sessions without discomfort. For my ears, these fit securely without sharp edges or uncomfortable pressure points, even during the longest listening sessions.

Thanks to their lightweight construction, you might even forget you’re wearing them—a major advantage if you enjoy long listening sessions.

The isolation is decent on the Hidizs MP143 Salt, considering it’s a vented design. Without music playing, you’ll still pick up some ambient noise, such as people talking or background chatter. With music playing, though, it can effectively drown out most of that. It may not fully isolate you in very noisy environments, but it strikes a good balance for day-to-day listening: it’s comfortable and offers enough sound isolation.

Note that for users with smaller ears, the Hidizs MP143 Salt will stick out a little, while medium or larger ear sizes fit about perfectly. Comfort might increase significantly when paired with the right tips, making it an even better listening experience.

Stock Cable​

The cable included with the MP143 Salt feels quite basic overall. If you are accustomed to some of the newer IEMs on the market, even at lower price points, you will notice how far this one falls behind, especially in terms of versatility and build quality.

To begin with, this cable is very lightweight—almost too lightweight, to the extent that it feels a bit fragile. On the positive thing is that there are no significant issues with microphonics, but its lightweight nature means that it simply does not stay in place comfortably. It also tends to tangle quite easily, which can be a pain—especially when trying to store it in a case or even during regular use.

Compared to some of the more premium or modular options available, this cable is clearly made from more budget-friendly materials. It is functional, but nothing about it truly stands out, and for daily use, you might find it somewhat lacking—especially if you have experienced higher-end cables before.

Overall, this cable would suffice for casual use, although it is certainly not the most practical or durable option. If you are the type of person who values a good cable, this one may leave you wanting more.

Tips​

The standard eartips that come with the Hidizs MP143 Salt leave much to be desired. They are rather basic and do not allow this IEM to shine as it should. The nozzle itself is quite short, and the walls are quite thin, making it difficult to achieve an effective seal. This affects both comfort and sound quality. It is quite disappointing that such a capable IEM has stock tips that are not up to the standard of the rest of the package.

Swapping out the stock tips with the NF Audio MS42 resulted in a noticeable improvement in sound quality. The MS42 tips provide a much better seal, which in turn tames the overall sound signature. The sharpness in the treble is significantly reduced, becoming more refined and less fatiguing. The midrange also benefits, sounding smoother and more detailed, while at the same time, the bass becomes better controlled and textured.

With the MS42 tips, the tonality quickly gave way to a more rounded, smoother, and better-balanced sound, greatly enhancing musicality and making for a far more enjoyable listening experience. If you want to get the most out of this IEM, I highly recommend giving these tips a try.

Tuning Nozzle​

Hidizs MP143 Salt features three tunings nozzles: Red, Silver, and Rose Gold, each having a different sound profile.

Red Nozzle: The nozzle has a focus on powerful bass, rich sub-bass, and mid-bass. It warms up male vocals but tends to overpower female vocals and instruments and darkens the treble.

Rose Gold Nozzle: Its characteristic sound is balanced, with controlled bass and not overpowering. The vocals sound clear and more natural; the instruments take on more presence, while the treble is well-defined without being aggressive.

Silver Nozzle: More mid and treble emphasis. It sounds much brighter and leaner. The female vocals sound very clear, while instruments have excellent detail and are brought forward as well, but there is practically no bass.

Personally, I preferred the sound of the stock nozzle, so I haven’t used the others as much. My full review will focus on the sound profile of the stock nozzle.

The Bass​

Sub-bass​

Yes, the sub-bass is there on the MP143, and it articulately handles the lower frequencies. However, if you’re used to that deep rumble or physical impact from a dynamic driver IEM, you may find the Hidizs MP143 a bit on the light side in this department. For tracks like hip-hop or bass-heavy songs, it doesn’t quite give you that chest-thumping feel. That said, I have heard this is not uncommon with planar magnetic IEMs, so I was not terribly surprised.

If you don’t always listen to genres relying on a lot of bass, such as hip-hop, you’ll most likely appreciate the balance it provides. It’s just that the sub-bass isn’t weak-it’s just a bit more contained and doesn’t swamp the rest of the music. In tracks for pop or classic music, the sub-bass is more than enough, and let’s be honest, unless you’re a basshead, you might not even miss the extra rumble.

Mid-bass​

The mid-bass is really where this set shines, in my opinion. I love a good punchy mid-bass, and the Hidizs MP143 nails it. It’s tight, impactful, and has just the right amount of body without feeling bloated. The clarity in this range is great, too. Listening to rock or metal, like “Hell on Earth” from Iron Maiden, drums hit hard, and the bass guitar sounds rich and full.

Separation between instruments is solid, and even with the heavier parts of the track, the MP143 does manage to keep everything in its place without it getting messy. It’s got that energetic feel which makes rock and metal tracks really enjoyable, and the vocals stay clear even with all the bass going on, which is something I really appreciate.

So, if you are one of those who really enjoy tight, punchy bass with decent control, you will probably enjoy the MP143. The sub-bass isn’t going to shake your bones, but it’s deep enough to be satisfying for most genres. And the mid-bass? That’s where it shines. If you’re not obsessed with having huge bass, I think you will really enjoy what MP143 has to offer.

Mid Range​

The mid-range of the Hidizs MP143 strikes a balance between neutrality and warmth and offers vocals clearly, with well-separated instruments, which is very important to keep everything from sounding clear and separated in complex tracks.

Male Vocals​

Male vocals are reproduced with decent weight and texture, hence sounding deep naturally. On Kiss from a Rose by Seal, his voice sounds rich in tone while having enough body to keep it from sounding light yet clear. The separation ensures the vocals stay up front even on top of the background instruments.

Female Vocals​

Female vocals- smooth, neither too warm nor too bright. In Killing Me Softly with His Song by Roberta Flack, her voice is soft and extended without any harshness or sibilance. Hidizs MP143 handles the upper frequencies delicately, making her voice soothing and easy to listen to.

Instrument Clarity​

Guitars and pianos sound clear, natural, and mid-range clarity assures that in populous songs, the vocals and instruments will not overlap and sound muddy. Guitars have a nice swing, and in general, the separation keeps everything tidy.

Hidizs MP143 Review: Warm and Smooth

Treble​

The treble on the Hidizs MP143 is smooth and well-extended, offering a good balance between detail and comfort. It does not possess that sharp or piercing sound that could lead to listening fatigue; it should be easy to listen to for long periods of time. For instance, in Killing Me Softly with His Song by Roberta Flack, the highs feel airy and open, adding a nice sense of space without any harshness. The treble extension is solid, and you can catch those subtle details like cymbals or high strings without being overwhelming.

However, where the treble is clean and controlled, it does lack a little sparkle to make it bright and energetic at the top. In tracks like Iron Maiden’s Hell on Earth, for example, the sound of the treble feels somewhat laid back, with some listeners perhaps missing a little bit of that bite or excitement, particularly during the high-pitched guitar solos. There’s decent clarity and detail, but it may get too smooth and restrained at times for aggressive treble lovers. In general, the treble has a natural sound and is pretty well-controlled. These could be ideal for listeners seeking a non-fatiguing sound, while listeners wanting highly energetic, bright treble should look elsewhere.

Hidizs MP143 Review: Warm and Smooth

Sound stage​

The Hidizs MP143 has a pretty decent, solid soundstage considering it is an IEM – not the widest I’ve heard. There’s a good sense of space and air between the instruments, but it isn’t going to run open-back headphones or larger IEMs for much of their money. Tracks like TOOL’s Invincible do a fairly good job of showcasing this spaciousness: instruments get enough room to breathe without sounding congestive. But more about being “wide enough” rather than really expansive, so if you’re looking for something with a huge soundstage, this might fall a little short.

Imaging​

Hidizs MP143 does a very decent job of placing instruments and vocals with good precision, making it quite easy to pinpoint their positions in the mix. On more complex tracks, such as Hell on Earth by Iron Maiden, imaging helps to keep everything fairly clear so you can tell where an instrument might sit in the track. It’s not ultra-sharp, but it’s good and reliable for everyday listening.

separation​

Hidizs MP143 impresses with neat separations of different elements in a track. Even in busier tracks that have so much layering, the bass, mids, and highs did not bleed into each other to help preserve clarity in songs like Praise The Lord from A$AP Rocky and Skepta. You might notice a little blending of instruments in very dense sections, but nothing too distracting.

On the whole, the soundstage, imaging, and separation are pretty good for a planar IEM in this price range. It’s not going to blow your mind with some kind of enormous stage, but it is well-balanced, clean-of-artefact presentation that works for the large majority of music out there. Yes, there are a couple of minor limitations, especially to soundstage width, but it’s satisfying and enjoyable to listen to.
Hidizs MP143 Review: Warm and Smooth

Conclusion​

The Hidizs MP143 Salt is a great place to start for anyone interested in planar magnetic IEMs without spending a fortune. It has a sleek metal design and a comfortable fit, providing a warm and smooth sound that can be enjoyed all day. While the standard cable and eartips may not be perfect upgrading to something like the NF Audio MS42 tips and good quality cable brings out the best in them. If you’re seeking for an IEM that strikes a balance between clarity and polished, smooth sound, the MP143 Salt could be the perfect choice. It isn’t perfect, but for the price, it provides a lot of value.

Hidizs MP143's Review - Another hit for the MP series?
Pros: Easy to drive
Solid build quality
DD like bass
Non offensive treble
Tuning options (interchangeable nozzles)
Cons: Shell is still on the larger side of the spectrum so as the nozzle
Might be a little too warm-ish for some

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. One year ago, I reviewed their MP145, which is the bigger brother of what I have today, the MP143. Hidizs is 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 shell’s size is slightly smaller compared to MP145, same goes for The IEM’s nozzle is slightly smaller than MP145, good news for those who were having fit issues with it previously. Packaging is the usual Hidizs style which looks minimalistic and also presents a premium unboxing experience. The box consists 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 MP143, 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 overpowers other frequencies, adequate amount for the fun factor if you ask me
  • Good texture on the bass and the speed is adequate for most genres unless you're talking about insanely high-speed heavy metal, but it is adequate to handle anything you throw at it
  • Slipknot's People’s= crap is being rendered effortlessly on MP143, 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 fairly thick with good textures, evident in low baritone note, doesn’t Upper mids are never offensive even when you turn up the volume, rather safe for those who are sensitive
  • There’s a slight bleed of mid bass into the mids, but most of the time they are okay
Treble
  • MP143’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 MP143 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
  • Overall it is quite good for the asking price
Driveability
  • MP143 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
  • Soundstage and imaging doesn’t really change that much based on my listening impression

AD_4nXe3vTK_Bv2PbHv8hEV3kt0Sk0n1mzy764brAUWpGYYgoPGgwrZBKheheKK3lwr8bozAuVHrOZLy1wOxlCJYbpmH6GjGxIPj5GJ9RjtTt79Wmpu2Gk9M3k7_ju4-_BwILrnZOsAh08AMdu_XCYWM3H-_8uA


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 does lift the treble up on the MP143, at the expense of reduced bass quantity, but if you find the MP143 is too warm, maybe this nozzle will suit you
  • Soundstage is slightly better with a little bit more air
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.

MP143 is an easy recommendation to anyone who is thinking to venture into planar iems or even seasoned audiophiles will like MP143 i’m sure, if you have tried the MP145 and think that the size might be too big or the 145 is slightly brighter to your taste, the MP143 is definitely the one for you.

Hidizs MP143 Salt : "Salty" or not?
Pros: Solid construction
Excellent bass response
Planar that sounds almost like a dynamic driver
A safe sound signature for most listeners
Useful tuning nozzles
Good accessories for the price
Cons: May exhibit some planar timbre (though very rare)
Stock ear tips leave a lot to be desired
The carrying pouch may not be everyone's cup of tea
Technical performance not at the level of other planar offerings
Introduction
The Hidizs MP143 is a 14.3mm planar magnetic IEM and successor to their MP145. Its cost is in the ballpark of $129-it really fluctuates quite a bit. It's crazy how this, being lower in price compared to the MP145, performs even better. Like the MP145, with three tuning nozzles, it allows for customizable sound profiles. Improved in sound and design, the MP143 made it even more intriguing to have it in any collection!

My experience
I've had the chance to hear the Hidizs MP145 earlier, and the sound was very good. It didn't sound like any other planar IEM in the market; the planar timbre was very minor, almost as if it were produced by a dynamic driver. But probably one trade-off I felt there was with regard to technical performance: it wasn't on the same tier as those other planar magnetic IEMs, it lacked in that aspect. Now with its successor, the MP143, all that has been magnified to positives, while retaining the same shortcomings in technical performance.

Unboxing experience
The box of the Hidizs MP143 Salt is relatively small. Taking the top lid off reveals the IEM shells, and beneath this compartment sits the carrying pouch, which contains the eartips, cable, and nozzles. Unboxing is rather basic and straightforward.

Build and design
The Hidizs MP143 Salt is made of CNC machined aluminum alloy and feels sturdy while being light. There is a version made from titanium alloy, but I don't have it on hand, so I cannot comment on it. Overall, the shells feel solid and lighter than the previous MP145, which is always a good thing.

DSC_0005 (25).jpg


The MP145 design previously was triangular in shape, with curved-in sides, along with strips on each side. For the MP143, only the strips, their name, and a triangular logo were attached to the shell. The strips have the design of two lines joined by a curvature, which, for me, looks better than the one used previously.

DSC_0025 (5).jpg


Fit and comfort
The fit on the MP143 Salt IEMs is excellent; these are designed to be a universal shape and aren't carrying any fins or complicated designs. It has made them rather easy for most people to wear in comfort; unless you have particularly small ears, they shouldn't pose any issues at all.

The comfort is also very impressive; they are even lighter than the MP145. I really don't see anyone having any problems with comfort with these IEMs.

DSC_0020 (6).jpg


Sound
Now, coming to the main part of this IEM, which is the sound. It's capable of producing whatever kind of sound you want. You may wonder how that is possible.

DSC_0026 (3).jpg


Well, the nozzles included actually work, not like some other IEMs we see out there in the market; this means a huge difference in sound. The rose-gold nozzle gives the most balanced sound, the red nozzle emphasizes the bass, and the silver nozzle gives a brighter sound profile.

Sub bass:

Red nozzle: It provides a formidable, richly textured rumble, which can always be distinctly felt in any mix. It's quite excellent at powerful sub-bass that resonates with clarity and depth-a very excellent option for people that love a strong low-end performance.

Rose gold nozzle: Sub-bass production is far more balanced and toned down, with still a decent amount of rumble going on. This makes the overall sound signature far more balanced, never overshadowing other frequencies.

Silver nozzle: Its presence is further reduced. The rumble is not completely gone, but less in amount for sure, since the emphasis shifts more to the mids and highs.

Midbass:

Red nozzle: The midbass hits with strength and power, which makes it very prominent in the overall sound. It also delivers a good amount of texture and clarity hence a blissful experience for anyone who loves such strong midbass.

Rose gold nozzle: The mid-bass is now more in balance, maintaining the punch but toned down-a lot like the sub-bass. The mid-bass does not bleed into other frequencies like it did with the red nozzle.

Silver nozzle: The mid-bass punch is less pronounced, and the reduced warmth makes the overall sound even leaner, which might not fit the taste of everybody.

Male vocals:

Red nozzle: As this nozzle amplifies the bass quite a bit, it warms up the lower mids, making male vocals sound warm, lush, and relaxed. However, the clarity takes a slight hit in general. Whether that is a trade-off you would be willing to make is completely up to you.

Rose gold nozzle: They are now evened out with the added warmth toned down, yet they still sound full and vibrant while maintaining a good amount of clarity as well.

Silver Nozzle: Male vocals lack the warmth and lushness they had, rather they have an upfront and clear presentation overall.

Female vocals:

Red nozzle: female vocals are overpowered by bass, therefore lacking liveliness and presence. They don't as upfront and lively as they should be rather they sound vague, hence less fun to listen to.

Rose gold nozzle: They no longer sound overshadowed or dull; instead, they are lively with a touch of warmth, creating a soothing listening experience. However, it might not be enough for people who prefer a more upfront and bright presentation

Silver nozzle: It makes them sound really bright, clear, upfront, and vibrant. While it might not be to everyone's taste, it certainly meets the desires of those that enjoy that approach.

Instruments:

Red nozzle: This nozzle's main priority is bass, the instruments are a bit overshadowed. They often sound less clear, not well separated and less detailed.

Rose gold nozzle: The bass no longer overshadows the instruments, giving way to them shining through in the mix. They don't pop at you with the highest clarity, but they still sound plenty rich and expressive to add depth without overpowering the overall sound.

Silver nozzle: Instruments now sound sparkly and clear, more upfront in your face with increased detail compared to the other nozzles.

Treble:

Red nozzle: Treble immediately gets much darker and loses air, sparkle, and brightness in general. This results in less detailed treble representation, which may be less interesting for listeners who liked a brighter profile of sound, yet it could just be what some people would like.

Rose gold nozzle: The treble section is well-balanced, offering plenty of detail without major harshness and sibilance issues. Overall it reaches an ideal treble reproduction.

Silver nozzle: In this nozzle, the treble is brighter, more energetic, and sparkly, with increased clarity and detail. This especially benefits the upper mids, creating a more spacious and open sound altogether.

Technicalities:

For technical performance, I’d describe it as a whole, meaning I won’t go into detail for every single nozzle. Instead, I’ll provide a summary of its overall capabilities.

Soundstage:
The soundstage varies in width depending on the nozzle used, performing just about average or slightly above. Overall, there are no complaints regarding height, width, or depth. If I had to nitpick, I’d say a bit more width would have been even better.

Imaging:
The imaging on this set is good—not exceptional, but effective. You can easily pinpoint the instruments, vocals, and other subtle details in the mix.

Detail retrival:
The detail retrieval on these is good, possibly slightly above average. Minute details are easily portrayed, allowing for a richer listening experience.

Dynamic and Transient Response:
Simply put, the dynamics on these are good. The transient response has improved compared to the previous MP145, but it still doesn’t reach the level of other planar options.

Power Requirements:
I’d say it doesn’t require as much power as some other planars; it can even be driven by a phone. However, it definitely benefits from the extra power for improved performance!

Tip Rolling:
I’ve paired it with the NF Audio MS42 eartips, and they do wonders for this IEM. I would heavily recommend these as a must-have for enhancing the overall sound and comfort.

The Hidizs MP143 is a brand new earphone that uses a 14.3mm large planar magnetic driver instead of a 14.5mm one as found in its more expensive sibling, the Hidizs MP145.

IMG_20240917_154001.jpg


Whale and Dolphin Conservation (WDC)

Hidizs is a strong supporter of the Whale and Dolphin Conservation association (WDC). The design of the Hidizs MP143 was inspired by the “Salt” whale and is the first earphone that comes with a plastic-free packaging. Hidizs packaging boxes and fillers are now entirely plastic-free, a concept called the "ocean-friendly packaging".

Hidizs wholeheartedly supports WDC in safeguarding whales and all marine ecosystems. Hidizs supports WDC’s outreach and education efforts to raise awareness about the ecological role whales play in the health of the ocean. Learning Salt's story highlights the crucial role whales play in maintaining the health of the oceans.

IMG_20240917_155210.jpg


Technical highlights

Back to the MP143, the 14.3mm diameter planar driver unit is custom-developed by Hidizs and utilizes nano-level planar speaker diaphragms. This large diaphragm offers advantages in audio information and dynamic range compared to other types of driver units. The system maintains a fully symmetrical magnetic circuit design, consisting of 7+7 N52H magnets arranged precisely. This design ensures lower harmonic distortion, enhances magnetic circuit efficiency, and achieves maximum magnetic flux close to 1 Tesla at the magnetic gap.

The Hidizs MP143, just like the MP145, features a unique Pneumatic Sound Tube Technology. It is equipped with three types of pneumatic sound nozzles that allow the user to achieve three distinct sound signatures simply by altering the airflow direction within the earphone chamber. The gold tube is for a balanced sound profile, the silver one for high frequencies enhancement and the red for boosting the bass.

IMG_20240917_154234.jpg


Non Audio stuff

The Hidizs MP145 is a bulky and rather heavy earphone with questionable wearing comfort. Thankfully, the ear-shells of the MP143 are not only more compact but also lighter (8g each) and the design of the faceplates is with less sharp corners and edges. The wearing comfort is much improved over the MP145, but still the Hidizs MP143 is not the most ergonomic and comfortable earphone to wear. The fit is also a little shallow because of its narrow shape and the short sound tube, while passive noise isolation is average.

The Hidizs MP143 is available in blue, black and silver finishes plus a limited titanium gold one. The MP143 is exceptionally well made and more beautiful looking than the MP145.

The cable

The 2-pin detachable cable is made from high-purity oxygen-free copper, ensuring low resistance and high conductivity. It is a well made, lightweight and soft cable with low microphonic noise and it doesn't get tangled too much. You have the option to order the cable with either a 3.5mm or 4.4mm plug.

IMG_20240917_154620.jpg


Accessories

The retail package includes a cable, two types of silicone ear-tips (balanced and treble) in three sizes each, three pairs of sound tubes in a small plastic case and a pouch bag instead of a regular carrying case.

IMG_20240917_154047.jpg


The Golden Titanium alloy version

The Hidizs MP143 is also available in a limited Golden Titanium edition that retails for $369. The differences from the standard edition are not only cosmetic as the titanium version is more carefully tuned to closely match the H-2019 curve. Hidizs claims that the sound performance is more stabilized and clearer than the aluminum alloy edition. The bundle of the titanium edition also includes two cables, both balanced and unbalanced, plus a WDC budget pin and a postcard collection.

Power requirements

With an impedance of 17 Ω and 103dB of sensitivity, the Hidizs MP143 is very easy to drive while it scales surprisingly well. You can use it with an entry level USB DAC adapter, like the Hidizs SD2, but you can do much better with something of higher quality, like the Hidizs S9 Pro plus.

IMG_20240917_155107.jpg


Audio stuff

The following impressions apply to the gold sound tubes that offer the most balanced tuning.

There are no surprises when it comes to the tuning of the Hidizs MP143 as it follows the H-2019 target curve, with some deviations here and there, just like the MP145. Actually, both earphones have a similar sound profile when the gold tubes are attached but the technical performance is not on the same level.

The MP143 has plenty of sub-bass that can handle all types of bass heavy music but the intensity is such that it doesn't overpower or cloud the mids and the treble. The low-end has the typical (by modern standards) bass and mid-bass emphasis that is considered as a crowd pleaser and offers plenty of satisfaction with most types of music, however tonal precision is not that suitable for critical listening. In the case of the MP143, these deviations are not as severe so you can listen to classical music as long as you are willing to accept some deviations from the ideal neutrality.

When it comes to technicalities, the bass is fast, tight and controlled with the famous planar magnetic clarity, layering and texture. It is also quite punchy and powerful, not as physically impactful as with large dynamic drivers, but still very realistic and resonant. The textures are a little lean but not that dry, this is a well defined bass that focuses on texture layering rather than weight and viscerality.

The mid-range has solid presence and a rather balanced tuning without sounding subdued or overly emphasized in the upper mid-range portion. Some of you might wish for some extra upper mid-range presence but I much prefer this safer tuning that is not fatiguing or shouting at the ears. The timbre is mostly natural, the mid-range of the MP143 is mildly warm and lush, expressive and melodious with ample harmonic density. Voices and instruments sound realistic and lifelike enough with good resolution and excellent clarity for the category.

The treble has the right amounts of presence and energy to make it sound sparkling and bright enough without leading into sharpening fatigue. The higher frequencies are crisp and vivid enough but still safe and controlled, making for a pleasing and rather smooth listening experience. This is not the most airy and luminous earphone but it is fast, with good detail retrieval and resolution that are more than enough for general listening without much compromises. The timbre is a little hollow and kinda weird at times (some people call it the “planar” timbre) but only in the highest octave and not that pronounced to spoil the overall listening experience.

The soundstage is not spectacular but still wide and spacious enough as not to appear congested or cramped. The presentation is mostly horizontal and places the listener quite close to the action while it is aided by decent imaging and separation. You can listen to all kinds of music without getting the feeling of a “sound wall” effect in front of your head.

IMG_20240917_154523.jpg


The sound tubes

You can use one of the three different sound tubes to fine tune the MP143 in order to align more with your listening preferences. Compared to the gold, the silver tubes add a bit of upper mid-range emphasis without altering the rest of the frequency response. Use them to add a little more sparkle and vividness to the sound and counterbalance the emphasized low-end.

The red nozzles are significantly more drastic in altering the whole frequency response than the silver ones. Not only do they boost the low-end, from the sub up to the mid-bass bass, but they also subdue the upper mid-range by a fair margin. The result is a bassier and darker sound signature with muted high frequency energy and compromised clarity. Use them for an intense, bass focused tuning with overly smoothed higher frequencies.

Vs the Hidizs MP145 (gold filters attached)

The MP143 is a warmer and slightly darker version of the MP145 with a bass that is slightly boosted but not on the same technical level and is also less physically impactful. The MP143 is smoother and more forgiving in the treble, the tuning is safer and more pleasing to the ear but it can't match the resolution, the clarity and the vividness of the MP145 which also has the lead when it comes to transparency and fidelity. The soundstage is also bigger and deeper in the MP145 which sounds more immersive and holographic with better separation. The most notable non audio difference is that the MP143 is more comfortable to wear and less heavy.

IMG_20240917_155133.jpg


Conclusion

The Hidizs MP143 might not have something new to offer as it follows the same kind of tuning with dozen other earphones but on the other hand it sounds really good and enjoyable with all kinds of music. An affordable earphone suitable for all those who want to experience the unique planar magnetic timbre and bass technicalities, the MP143 is going to please with all kinds of music and satisfy with the combination of its punchy bass and smooth treble without compromising mid-range presence.

The review sample was kindly provided free of charge in exchange for an honest review. The price of the Hidizs MP143 is $129 and can be ordered from the Hidizs online store.

WHALE, WHALE, WHALE. Guess who's back?
Pros: - Strong sub bass
- Improved comfort compared to big brother
- Technicalities that rival more expensive IEMs
Cons: - Still large fitting
- Noticeable planar timbre
- Thin cable
HIDIZS MP143: S A L T

"LET'S GET READY TO RUMBLEEEEEE!"

This IEM was provided by Hidizs for an honest review.
This review is subjective and written as objectively as possible.

**PREFERENCES**

My sound preference is V-shaped, mild V-shaped or U-shaped but overall I enjoy bass. I prioritize tonal, timbre and coherence over general technicality.

My daily setup is:

- Ibasso DX300
-Astell&Kern SE200
- Beyerdynamic Xelento with Midas Cable
- Custom IEM "NVD"
- Various eartips


Preferred genres:

- Hip-hop
- Orchestra/Scoring
- K-pop
- Nu-Rock
- Fast-paced music


PXL_20240922_132908213.jpg


**INTRODUCTION**

It feels like it was just yesterday when the grand whale made its entrance, shaking up the planar scene in the audio world, and its younger sibling has already arrived.

In case you're confused as to why this is called the Whale, Hidizs partnered with Whale Dolphin Conservation (WDC) which dedicates its conservation efforts to safeguarding the lives of whales and dolphins in the wild.

The design of the MP145 and MP143 are both inspired by whales. The MP143 takes its theme from the Humpback whale. As such, I'm crossing my fingers that the next product will take its appearance from the Orca and be designed to be a "planar killer."
*I wish

**ACCESSORIES**

The MP143 packaging is specifically designed to exclude plastics to reduce pollution in the oceans and the environment.

**Contents of the box:**

1x MP143 drivers
1x 3.5mm/4.4mm cable
1 set of small bore eartips
1 set of wide bore eartips
1 set of tuning nozzles (red, rose, silver)
1 carrying pouch
1 warranty card
1 WDC pin with an adorable whale icon 🐳 (pre-order only)


PXL_20240922_133114886.PORTRAIT.ORIGINAL.jpg


The accessories are all standard but I have a comment about the cable of this MP143.

It looks like KZ cables at a quick glance.
The cable is as thin as a single noodle.
Hidizs usually has better cables than this; the MS5, MS3, MP145 all have great quality cables. Except for this one.

**CONFIGURATION**

Like its older brother, the MP143 packs a planar setup but with a little difference. This time, Hidizs opted for a 14.3mm planar driver (0.2mm smaller than the MP145).

So with the smaller planar driver, how's the sound? Worse you might think? HELL NO!

This planar driver is called the FAST 2. It's advertised as producing a magnetic force of nearly 1 Tesla which means the dynamics and technicalities will be crazy good.

PXL_20240922_132817920.jpg


**FITTING**

We all know that a primary con of the original Whale MP145 was its size, so how does its smaller sibling fare?

The MP143 has noticeably smaller drivers than its older brother and they are also more ergonomic. Personally, I had no fitting issues with the MP145 but the MP143 is definitely FAR more comfortable to wear.
So if you didn't find the OG comfortable, the MP143 should fit your ears better.

The drivers are still large and bulky so the main concern with this IEM will always be fit.

Have to give the credits to Hidizs though, they listened to the customers.
GOOD JOB!

PXL_20240922_132731522.jpg


**SOUND IMPRESSIONS**

In short,
the MP143, which I will henceforth refer to as "Salt," is a bassier version of the MP145.

The Salt comes with 3 tuning nozzles: Red Bass, Rose Gold Balanced, and Silver Treble.

I will be using the Rose Gold nozzle with stock small bore eartips for this review.

**BASS**
Compared to the midbass of the MP145, Salt focuses more on the sub-bass, providing very satisfying rumble. This bass is boomy and has a decent texture for a planar. You can feel the sub-bass in your head and it provides an immersive experience.

Why did I use the words "decent texture?" Because I must acknowledge that the texture of the bass still falls short of that delivered by dynamic drivers.

Nevertheless, the punch from the bass Salt makes up for the lack of the MP145's emotional impact.

**MIDRANGE**
When compared with the Whale, the Salt has a thinner overall sound. This makes the planar timbre feel more prominent than in the original model.

Don't get me wrong, this doesn't constitute a deal breaker but the midrange performance was also a minor letdown with the MP145 and this remains the case with the Salt. The less-than-ideal vocal performance was especially evident in male vocals, which could come across as lifeless and unemotional.
If you're into lush, wet, emotional vocals, the Salt probably won't fit your needs.

On the other hand, the fast transient performance of the planar drivers makes guitar plucks sound exceptionally crisp and defined. I could feel the speed of the guitar strings and the movements of the guitarist's fingers as if I was watching live.

**TREBLE:**
The difference between the MP145 and Salt is most apparent in the treble. The MP145 focused more on extension and had an airy and spacious sound but lacked in sparkle and grit. The Salt, on the other hand, has more of a presence in the treble and more sparkle.

Presence in the treble means the Salt has a more pronounced bite and feels more edgy in its note definition, unlike the smoother treble in the MP145.

On one hand, the more aggressive treble of the Salt makes each note or song feel sharper, more "hi-fi" and less "analogue" for lack of better words, with a more precisely defined sound. Think of it as a sharp filter used to edit an image.

On the other hand, some notes will have a spicy aftertaste that can occasionally be overpowering.

The Salt also has noticeably less air than its older brother, The MP145.

PXL_20240922_133129958.PORTRAIT.ORIGINAL.jpg


**TECHNICALITIES**

**SOUNDSTAGE:**

They have the same spaciousness and has this unique grandeur feeling. However, in comparison to the MP145, Salt has more grandeur on the left and right where it feels as wide as the ocean. In terms of three dimensional aspect, it wasn't very apparent since the sound from planars is generally two-dimensional.

That said, Salt doesn't have any problems in conveying distance between instruments. It's not the strongest point of the Salt, but it's definitely not something to worry about if you ask me.

**IMAGING**:
Related to the soundstage, the stereo imaging is superb. With an IEM that has poor stereo imaging, sometimes songs may mix instruments from the left and right channels making it difficult to hear individual instruments.

None of that happens with Salt.
In fact, it has incredibly accurate imaging which means you could close your eyes and tell me where the sound is coming from.

**TIMBRE:**
The Salt has a noticeable planar timbre and you can immediately tell that the sound is coming from a different source. This is unlike the more natural timbre of dynamic drivers.

**COMPARISON**

**Artti T10:**

The T10 has a noticeably more balanced tonal character and the timbre is also more natural than that of the Salt.
In terms of technicality, the Salt wins by a landslide. It also provides better instrument separation.

**Zetian Wu Heyday:**
The Heyday has a more natural timbre than the Salt but presents a smoother and less distinct sound. The Salt has a sharper note definition. In terms of technicality, the Salt falls short in imaging where the Heyday feels more accurate and three-dimensional.

**KZ PR2:**
The planar timbre of the PR2 is stronger than that of the Salt. The sub bass of the Salt clearly overpowers the PR2 and the midranges of both models are just okay. I found the treble present in the PR2 to be more energetic although it can sometimes be overly energetic and causing sibilance problem.

SONG USED:
Wonder Girls - Nobody
Kyouran Hey Kids
Canon Rock
Hans Zimmer - Pirates of the Carribean
Blackpink - Typa Girl
50 Cent - In 'da Club
Nao Touyama - Off
Utada Hikaru - Merry Christmas, Mr. Lawrence
AoT OST. - Call your name
Eminem - Till I collapse
Versailles - Philharmonic Quintet - Silent Knight
AND MANY MORE...


**CONCLUSION**

The Salt has all that it takes to be a contender and a good choice for the price range of under 150$

If you fancy the technicalities of planars as it combines the crazy fast transient response and ear-shaking bass, MP143 is a no-brainer.

And for anyone who orders the Salt, your money is used to help keep whales and dolphins out of harm's way 🐳🐳🐳

Thanks for reading. I tried changing my writing style from the descriptive to the narrative. I hope it wasn't too boring!

See you!

143 does not mean I love you | MP143 Thoughts

Disclaimer:​

I’m more of a Tech head than audiophile and I use YouTube Music for 99% of my listening. Take everything, I say with this in mind and please don’t come after me for not having refined taste. This is purely from my silly little point of view, of which you might be interested in.

Gear Used:​

Streaming Platform: YouTube Music Premium (Bitrate: 256kbps AAC & OPUS)
Dongle: USB to Lightning JCALLY JM08L

Box:​

As usual, I’m a big fan of practical packaging and this being right up there. The MP143 comes in a simple yet classy box with everything it comes with inside. It comes with 2 sets or ear tips with 3 sizes each which amounts to a total of 6 total ear tip pairs for you to choose from and a leatherette pouch that uses a tension clasp mechanism that you have to push into to open.

I honestly love the little pouch this thing comes with. It provides a nice compact carrying case without being extremely bulky but at the same time convenient to throw in and out of your bag. The Hidizs logo is subtly stamped on the front of the bag which is a nice little touch to break up an otherwise plain pouch. One thing to note is that the inside of the pouch tends to catch on any Hook & loop type material so if you have a cable organizer made of that then you should probably not use it in tandem with this case because it’s kind of a pain to remove without feeling like you’re ripping your little pouch friend inside out.

Build:​

The shells themselves are built pretty solid without being too heavy and it’s got a nice matte finish to it making it nice to hold and handle as well. I do wonder how long the finish will last if you’re the kind of person who accidentally bumps them together all the time but so far during my time with them, I haven’t had any issues yet.

The cable it comes with is also this nice shiny silver color with a thin diameter that follows all the way up to the ear hook so if you’re an optically challenged person who needs pieces of glass for your eyes then these should hamper your daily wear in any way. Although it’s a perfectly fine cable it tends to be a little stiff and unforgiving which in turn also makes it a little cheap feeling. It’s not that much of a big deal but it can be a little messy if you just put your DAP or Phone on the table and it kind of just sits there.

If there’s one thing to note about the build itself is probably how wide this thing is. It’s not super big mind you but it’s definitely on the upper end of IEM size and with its sharp edges it probably will be a little inconvenient if you’re using a carrying case that’s just right for it because it might dig into things if placed awkwardly

IMG_2968 3.JPG

Sound:​

The MP143 is my first crack at checking out planar magnetics and they definitely disappoint any of my expectations. The biggest difference I definitely noticed is how tight the low end can get (😏) regardless of how many things are going on. Although it definitely feels a touch closer and less open than most of the things I’ve tried, it really doesn’t dilute any of the experience you get out of it.

In Aono Shioriuta - FantasticYouth, the toms roll during the pre-chorus sound thumpy. It feels like it's my first time hearing them after hearing this song so many times. The clarity of imaging on these especially in something like Hurt Somebody (Alex Adair Remix) - Noah Kahan & Julia Michaels shocked me with where everything was at. all the sub bass in If the World Was Ending (Marian Hill Remix) - JP Saxe & Marian Hill just reverberates through my entire being with how it feels in my head.

Nitpicks:​

I probably sounded a little too enthusiastic with how it sounded and while everything I said was true, I only ever got to enjoy how this thing sounds a few songs at a time before they’d either pop out or just make my ears hurt from being shoved in for too long. These things just don’t fit me in any shape or form. I tried all the tips included and even the ones on my daily driver but nothing would get them to have a solid seal and a consistent fit. If I wanted them to get a somewhat decent seal for a bit I’d have to twist them in this weird awkward angle and then the cable pins would be too far out and make the ear hooks practically useless at that point.

This is clearly a subjective thing but if you’re like me who tends to lean towards more ergonomic shapes with a smaller and deeper fit then I’d suggest you find a physical pair to fit just to be sure because I honestly did not enjoy my time with these too much no matter how good they sound.
IMG_2967 3.JPG
IMG_2966 3.JPG

Final Thoughts:​

For $159 these things aren’t the cheapest things around but in the grand scheme of planar magnetics I think they present a pretty good value proposition especially if you’ve never experienced this kind of technology before. Just be sure to do your due diligence when it comes to fitment because these things definitely have a pretty unforgiving shape so if they don’t fit you properly there’s really not much work around there.

While I didn’t really enjoy my time testing them I can still appreciate the sound they offer and if you’re like me who’s never tried planar magnetics before BUT you’re confident these will fit you then I don’t think you’ll be disappointed whatsoever with your purchase.

But remember, music is a personal experience and you should find the gear that makes you enjoy your music the most regardless of what a graph says.

Thanks to Hidizs for providing this review sample to Audio reviews Downunder. These are my honest reflections and assessment of the new model.

The MP143 is provided with two sets of tips and three pairs of tuning nozzles. There is a soft carry bag in the box. The provided 4.4mm balanced cable is OK quality but a little light and less than premium. I'd like to see Hidizs step up and supply a better cable as one of the other planar makers do.
Testing done with Hiby R3 DAP, Letshuoer DT03 and Cayin RU6 DACs, Open-heart cable and Divinus velvet open bore tips.
The elephant in the room
Hidizs had great success with their first planar the MP145. Designed with a whale fin motif and donating to certain research it was a distinctive design and was received very well by reviewers and consumers. The one criticism was its physical size. Hidizs responded with a smaller shelled model, again whale fin influenced and a slightly different planar driver. 13.3mm vs 13.5mm. Obviously the audiophile audience will want to know how the smaller model stacks up against its bigger brother. So, I will be referring to the 145 in this review.
PXL_20240916_064257067.MP~2.jpg


Fit and comfort.

Like the 145 it's fairly big even though it's smaller than big brother. The contact with your pinna is virtually the same and I find both comfortable. It is a little lighter but there is still a chunk of metal hanging out of your ear. For me there are no issues.



Driveability.

MP143 performs well with mid volume settings. The 145 scales up with 44 to 46 volume settings. The 144 works best at 38 in my setup. Because it is a fuller sound it's very satisfying at these levels. Boosting the volume does not bring the gains of its big brother.

Nozzles.

Bass, balanced or treble? Once you have decided the two rejected sets go back in the box. Hidizs nozzles do change the sound significantly. Generally, they affect the bass and raising this changes the perceived mid and treble mixed and the good thing with the MP143 is that good bass depth is retained even with the treble nozzle. Choosing the bass one took too much sparkle out and the rose gold balanced option, while very good left me wanting a less forward, less warm vocal and more details and sparkles up high. So treble nozzle for me. No issues with sibilance of shoutiness. Refined and detailed.

PXL_20240916_211436919.MP.jpg


The Sound & Bass

My initial impression was...
Damn..! This thing has still got the 145 DNA but with more bass. Mid bass is there in spades. The MP143 GROWLS! But the vocal clarity and naturalness is still there. Much better than NiceCHK F1Pro and all the Letshuoers. Mid bass hits hard with a complimentary sub bass component. The bass is fast but with great physicality. Bass guitars in particular can be felt as well as heard. This is a solid bass that's a tonne of fun and leaves the midrange to do its thing on top with no bleeding or masking the vocals. It digs deep but there is no boominess. You can tell I'm a fan.
On reflection after A/B comparing with the 145 I will correct myself, as the bass on the bigger planar model is still great, if more sub bass focused. It's also influenced by the wide soundstage. It has more room to fill.


The sound stage.

This was what I was most interested in as the MP145 large planar with its twin vents has an expansive soundstage with its ability to move air. The MP143, apart from two small holes in the shells, is a smaller sealed unit. I was expecting a reduction but unsure what I would hear. I am pleased to report that the soundstage is rather good with good width and is helped by the excellent instrument separation and airy presentation. If I was forced to compare, I'd say the 145 is an outdoor stadium and the 143 is an indoor 1930's concert hall.



PXL_20240916_064504258.MP.jpg


Midrange/Vocals.

The vocals are very similar to the MP145. Very little BA timbre if any to my ears. I compared with my best single DD vocal IEM and the 143 compared well. The extra midrange density and warmth really did not alter or add to the vocals. Everything was finally very natural to my ears.


Treble
I'm using the silver treble nozzles as my preference. Again, benchmarking with the MP145, the Salt model, as Hidizs has called it, has virtually identical treble character, with very clear clean hi frequencies and no sibilance or hardness (to my ears). The difference in in perception. The boosted midrange tends to temper the treble and reduce its prominence.

PXL_20240916_065108183.MP.jpg


Conclusion

One think that needs to be said when comparing the two Hidizs planars is that they are quite different. MP143 has a 13.3mm driver MP145 a 13.5mm. the MP143 is by no means a baby 145. It is unique planar with its own tuning and character. The mid-range boost provides a warmer and perhaps a slightly less planar sound. Very easy to listen to and very musical. I would be happy to own both and treat them as separate high-quality IEMs. As to which I would be stranded on a desert island with ? It wouldn't matter. I'd be happy with either.

HIDIZS MP143 SALT: A PINCH OF SALT FOR YOUR MUSIC


INTRO:


Wheals again! The successor of ‘MP145, the king of Planar’ is here with 14.3mm planar magnetic driver, named ‘Hidizs MP143 Salt.’ Just like MP145, it comes with three tuning nozzles, which is awesome. They have even given it its own name- ‘SALT.’ The name comes from the legendary female humpback whale, who is thought to be the oldest known humpbacks anywhere. Interesting, right? But that’s not all—this set is designed in collaboration with Whale and Dolphin Conservation (WDC), known for their whale conservation activity worldwide. Sound wise, this is a fantastic musical set with perfect warmth and rich detail across all frequencies. One of the biggest complaints about the MP145 was that it was super bulky and heavy. They made the MP143 smaller and lighter (compared to MP145), so its more comfortable to wear. This is one musical set you don’t want to miss out.

CONTEXT:

I’m a huge fan of Hidizs MP145, especially for its sound signature and that amazing holographic soundstage. So, when I heard they were launching the MP143 on Kickstarter, I couldn’t wait to get my hands on it. The moment I got the review unit, I drove right in, opening up my massive music library. And wow—the sound is so soothing and enjoyable. My ifi Hip DAC-2 paired really well with it, delivering this super smooth, warm tone with a lovely melodic midrange and treble. But when I used the MP143 with the Fosi Audio DS-1, iBasso DC04 Pro, Celest CD-10, and Hidizs S8 Pro Robin, that was when it truly came to life, opening up a wider soundstage. And, as always, my Cowon Planue R2 nailed it perfectly. It did feel a bit bright with my Moondrop Dawn Pro, even with the red nozzle. I didn’t bother swapping out the cable because it already feels fantastic with the IEM, but I did roll tips to find the perfect match. I will dive deep into the cable & ear tips later on in this review.

UNBOXING EXPERIENCE:

Unboxing the MP143 is an excellent experience if you are a nature lover. The whole idea behind the packaging is to cut down on plastic waste, which is awesome. Hidizs shared a pretty eye-opening stat: “Humans produce over 430 million tons of plastic annually, mostly single-use, threatening oceans.” So, with some guidance from the Whale and Dolphin Conservation (WDC), they’ve created their first ever plastic-free packaging for audio products. This “ocean-friendly packaging” really shows how serious Hidizs is about protecting marine life and supporting WDC’s mission. I think this is a great step forward.

When you open the cardboard box, you’ll find the IEMs nested in a corrugated paper cutout instead of the usual foam. Underneath, the stock cable and ear tips are neatly tucked inside a carrying pouch. It’s not super fancy, but it doesn’t feel cheap either. Honestly, I think more companies should follow Hidizs’s lead and take a stand for nature conservation. Big props to Hidizs for making this move!

BUILD QUALITY:

The MP143 has a shell made from CNC-machined, one-piece aluminum alloy, which feels super sturdy. It’s definitely lighter and smaller than the older MP145, which is a nice improvement. The faceplate design is pretty cool too—it’s inspired by the texture of a whale’s fin, which adds a nice touch of character. The nozzle is on the shorter side, but it works well with the lightweight aluminum tuning filters, which fit snugly thanks to the rubber gasket. The supplied cable is impressive for the price. It’s made from high-purity, oxygen-free copper, and mine came with a 4.4mm balanced plug. The stock ear tips are made of liquid silicone, but honestly, they don’t do the IEMs justice. The carrying pouch is basic, but it does its job. Overall, this is a solid, well-built IEM with good accessories that are made to last.

ARIF9505-Enhanced-NR-Edit.jpg


ARIF9515.jpg




FIT & COMFORT:

Remember the fit issues with the MP145? Well, they’ve fixed that with the MP143. Thanks to its smaller shell design and lighter weight, it’s way more comfortable for longer listening sessions. Hidizs claims you “might not notice it’s there,” but let’s be real—you can still feel it. That said, the lightweight aluminum shells make it easy to wear for extended periods without discomfort. The shorter nozzle might feel a bit awkward at first, but you can easily fix that by finding the right ear tips. Speaking of ear tips, the ones that come with it aren’t the most comfortable, even though they’re made of liquid silicone. But the stock cable is a nice touch. It’s soft, doesn’t put pressure on your ears, and has no microphonics, even if you’re out jogging. Overall, the MP143 is a super comfortable set to use.

ARIF9851-Enhanced-NR-Edit.jpg




SOUND IMPRESSION:

Now let’s get to the main part of the review—the sound. It has really nice tuning, leaning towards a warmish sound. It comes with three pneumatic sound-tuning filters, and each one gives a different experience. If you consider the ‘Balanced (Rose Gold)’ filter as the middle ground, the sound feels like warm-neutral with lot of dynamic details and technical precision. The ‘High-frequency (Silver)’ filter makes the upper-mids and treble livelier, while the ‘Low-frequency (Red)’ filter boosts the sub-bass and adds overall warmth.


Next up, we’ll check out the frequency graph for each filter and then dive deeper into the sound details.

Freq Res- Rose Gold.jpg


Freq Res- Quiet Silver.jpg


Freq Res- Charm Red.jpg




SUB-BASS:

● Testing Tracks:
● My hometown- Bruce Springsteen
● Feels like teen spirit- Nirvana
● Anchor- Novo Amor


Rose Gold filter: With this filter, the sub-bass is well-controlled and balanced. It provides a solid rumble, reaching low frequencies without overwhelming the rest of the sound. It’s not as intense as the Red filter but gives a natural, clean sub-bass that blends well with the overall signature. This makes it a great choice for those who want impactful sub-bass without sacrificing clarity.

Silver filter: The sub-bass here is slightly reduced compared to the Rose Gold filter. It still provides depth, but the focus shifts more toward the upper frequencies, leading to a less pronounced low-end. While the sub-bass is still present, it takes backseat to emphasize treble & midrange detail. This filter is ideal for listeners who prefer a brighter sound with lighter bass.

Red filter: This filter is designed to boost the low end, and it does so effectively. The sub-bass is deep, powerful, and has a strong presence. This creates a rich, warm sound with a substantial rumble that bass enthusiasts will love. But it has a little drawback; the enhanced sub-bass bleeds slightly into the mids. The Red filter is perfect for those who enjoy bass-heavy genres like hip-hop or electronic music.



MID-BASS:

● Testing Tracks:
● Every breath you take- The Police
● Constant Craving – K.D.Lang
● Man on the silver mountain- Rainbow


Rose Gold filter: It provides a balanced approach, where the mid-bass is present but not overly emphasized. It delivers a clean and textured bass response, making it suitable for most genres. But it does trade off some airiness in the higher frequencies, slightly reducing brilliance. Still offers a middle ground with tight and controlled bass though.

Silver filter: With this filter, the mid-bass becomes a bit leaner. The focus shifts more toward clarity and transparency in the sound, with less warmth compared to the Rose Gold filter. This results in a crisper and cleaner bass performance, though it might feel slightly less full or punchy to some listeners.

Red filter: The Red filter really boosts the mid-bass, making it much more pronounced and giving the sound a warm, lush character. But the downside is, it reduces clarity and the mid-bass sometimes bleeds to the midrange like it does with sub-bass. This character makes the overall sound feel heavier and less defined. It may perfect for bass lovers, but it may not be ideal if you’re looking for a highly detailed or neutral sound.

ARIF9895-Enhanced-NR-Edit.jpg




MALE VOCALS:

● Testing Tracks:
● Paradise city- Guns N’ Roses
● I am the highway- Audioslave
● Late Goodbye- Poet of the Falls


Rose Gold filter: This filter delivers a balanced sound with a warm and natural timbre. Male vocals sound rich and full, with a good amount of presence, though not overly forward. It's a great option if you're looking for warmth and body without losing too much clarity.

Silver filter: The Silver filter brightens male vocals, making them sound more forward and detailed. This results in a crisper and more energetic presentation, but it might lose some of the warmth you’d get with the Rose Gold or Red filters. It’s perfect for those who prefer clearer vocals over warmth.

Red filter: The Red filter emphasizes bass, making male vocals sound warmer and lusher. But this added warmth can sometimes reduce vocal clarity, as the bass can bleed into the mids, making the sound feel more laid-back and less precise. This is ideal if you prefer a smooth, rich sound but might not be the best choice for those who prioritize vocal clarity



FEMALE VOCALS:

● Testing Tracks:
● Here we are- Gloria Estefan
● I hate myself for loving you- Joan Jett
● By your side- Sade


Rose Gold filter: This one smooths out the midrange, making female vocals sound more natural and balanced. It's not as bright as the others, so it’s great if you like a more laid-back and warm tone. The treble is still detailed, but it’s not harsh, so it works well for female singers without pushing their voices too forward or sharp. But it might lack a bit of sparkle for those who enjoy a brighter presentation.

Silver filter: This is the brightest of the three and really brings female vocals to the forefront. If you love crisp, energetic vocals with lots of clarity, this is the filter to go with. It adds brightness and makes the upper mids more prominent, so female singers like Gloria Estefan or Sade will sound clear and dynamic. But for sensitive listeners, this might feel a bit too sharp or "spicy" at times.

Red filter: The Red filter adds warmth and thickness to the sound but sacrifices some clarity and energy in the upper mids. Female vocals become warmer and softer, but they might feel a bit muffled or less defined compared to the other filters. This is great for those who prefer a more relaxed and less aggressive sound, though it might not be the best choice if you value vocal detail.

ARIF9609-Edit.jpg




INSTRUMENT SEPARATION:

Testing Tracks:
● Kiss from a Rose- Seal
● In your eyes (Secret World Live)- Pete Gabriel
● Shine on you crazy diamond (P.U.L.S.E)- Pink Floyd


Rose Gold filter: This is the most balanced filter of the three. It provides decent instrument separation, but it slightly softens the high frequencies. The overall separation is clear and enjoyable, though not as detailed as with the Silver filter. It's a solid middle-ground option, giving a nice blend of warmth without losing too much clarity.

Silver filter: This filter enhances treble and detail, making instrument separation the most noticeable. It gives the MP143 a much crisper and clearer sound, which allows instruments to stand out better in complex tracks. If you prefer more definition and air between instruments, the Silver filter is the way to go. It adds extra sparkle, which helps isolate individual sounds more effectively.

Red filter: The Red filter shifts the focus towards bass, which can make the sound a bit congested. This filter emphasizes more on the low end and tends to overpower the finer details in the midrange and treble, making instrument separation less clear. While it might be fun for bass-heavy genres, it doesn’t offer the same clarity or precision as the other two filters.



TREBLE:

Testing Tracks:
● Sad but true- Metallica
● Learn to fly- Foo Fighters
● Carrie- Europe


Rose Gold filter: The treble with this filter is smooth and mildly bright, with an adequate amount of sparkle and detail. It's not harsh, making it comfortable for longer listening sessions. But some might find it lacking in airiness and brilliance compared to more treble-focused IEMs. Overall, it delivers a good balance between brightness and control, without being too sharp.

Silver filter: This filter enhances the treble, bringing out more brightness and detail. It adds a noticeable lift in clarity, especially in the upper mids and presence regions, without introducing sibilance. The treble sounds more energetic and detailed, making this filter ideal for those who prefer a livelier, more open sound signature.

Red filter: With the Red filter, the treble becomes more subdued and darker. It loses some brightness and air, which may cause the sound to feel a bit veiled or less defined, particularly in the higher frequencies. This filter is best suited for listeners who prefer a warmer, bass-focused sound and don’t mind sacrificing some treble clarity.



SOUNDSTAGE:

● Testing Tracks:
● Brush with the blues- Jeff Beck
● Foxy – Tokyo Groove Jyoshi
● November Rain- Guns N’ Roses


Rose Gold filter: This filter offers a moderate to wide soundstage, providing good lateral width and some height. It feels spacious enough for most genres, with a smooth balance between width and depth. However, the sense of airiness in the soundstage might feel a bit dampened, especially in comparison to the Silver filter.

Silver filter: The Silver filter creates the widest and most open soundstage of the three. It enhances clarity and provides a more immersive experience with better imaging, allowing instruments and vocals to be positioned more precisely. The added treble brightness also contributes to a better sense of space and separation.

Red filter: With this filter, the soundstage becomes narrower. The focus shifts towards a bass-heavy, more intimate presentation, which can make the stage feel more closed-in. This filter is best suited for listeners who prefer a warm and rich sound, though it sacrifices some spaciousness and definition in the process.

DSC_0004.jpg




POWERING IT UP:

Usually, Planar Magnetic drivers are power hungry. But the MP143, with its 14.3mm driver, is not that much difficult to drive. Even a 3.5mm jack from a smartphone can drive it easily. But you won’t get the best sound from this IEM just using a phone alone—you'll need at least a basic DAC dongle to really hear what it can do. I tested it with several options like the Hidizs SD2 (which only has a 3.5mm output), Moondrop Down Pro, Hidizs SD8 Pro, Celest CD-10, Fosi Audio DS-1, iBasso DC04 Pro, and all these dongles did a great job driving the MP143. So, powering this IEM isn’t a big issue at all.

ARIF9627-Edit.jpg




CABLE & TIP ROLLING:

I mentioned earlier in this review that, while the supplied cable is good enough to use but the stock ear tips aren’t up to par. So, I tried out a bunch of different ear tips like Spinfit W1, Omni, Tangzu Tan Sanchi Advanced, Divinus Velvet (regular & wide boar), Dunu S&S, Dunu Candy, Penon Liquer (Black & Orange) etc. and found that the Spinfit Omni is ultra comfortable for longer listening sessions. But if you are not a marathoner like me (who listens to music for 5-6 hours straight) Dunu Candy is a great choice for sound quality. It really brings out the lower frequencies far better than the W1.

ARIF9886-Enhanced-NR-Edit.jpg




Who should get the MP143:

● Smaller, lighter design:
If you prefer a smaller and lighter IEM, the MP143 is more comfortable for longer listening sessions, especially for users with smaller ears.

● More affordable: The MP143 is priced lower than the MP145, making it a great option for those seeking a high-quality planar IEM at a more budget-friendly price.

● Versatile tuning options: With its three tuning filters (Rose Gold, Silver, Red), the MP143 provides flexible sound profiles, allowing users to switch between balanced, treble-boosted, and bass-heavy sound signatures depending on their preference

● Balanced sound: The MP143 offers a balanced sound profile that works well across a wide range of music genres, making it suitable for those who enjoy versatility in their listening experience

● Good for casual listeners: If you’re a casual listener or someone who enjoys a slightly warm and engaging sound but don’t need extreme technical performance, the MP143 will provide a fun, enjoyable sound without being overly analytical.



Maybe look elsewhere if:

● Neutral sound lovers:
If you prefer a flat or more neutral sound signature, the MP143’s tuning, especially with the red filter’s bass emphasis, might feel overwhelming. The warmer, bass-boosted sound might lack the transparency you’re looking for.

● Fans of wide soundstage: The soundstage of the MP143, particularly with the rose gold and red filters, is more intimate and not as wide or expansive as some other IEMs. Those seeking a large, airy soundstage might need to look elsewhere.

● Listeners seeking maximum detail: While the silver filter enhances clarity and separation, overall, the MP143 isn’t the most technically precise IEM in its price range. Audiophiles who prioritize the finest details and micro-nuances may find better options for analytical listening.

● Bass-heavy listeners: While the red filter provides a solid bass boost, true bassheads who prioritize sub-bass rumble and impact may find the MP143’s bass performance somewhat lacking compared to IEMs specifically tuned for heavy bass output.

ARIF9860-Enhanced-NR-Edit.jpg




CONCLUSION:

What makes the MP143 stand out is not just the sound, but how it adapts to your mood. Whether you’re in the mood for clarity, excitement, or warmth, this IEM responds. It’s not about perfection in any one area, but about versatility—a chameleon that shapes itself to fit your desires. You can sense that, while it may not have the massive presence of its older sibling, the MP145, it’s a smaller, lighter, and more approachable companion, like a friendly guide through your music library. The beauty of the MP143 lies in its ability to make you feel like you’re part of something bigger. Whether you’re walking through the city or sitting at home, it’s not just an IEM; it’s a musical journey, where every note carries you along like the ebb and flow of the tide. And in the end, it’s a journey worth taking.

An MP145 but cheaper?
Pros: Build, aesthetics, performance...
Cons: Compact soundstage, not the most detailed, can sound a little "rounded"...
DSC_5631.JPG


TLDR version on YouTube: TDLR - Hidizs MP143

The Hidizs MP143 have been sent to me directly by Hidizs in exchange for the publication of my review. Their only request was that I published it around the release date, however, as I was on vacation when these IEMs were officially announced, I guess I failed to meet that request.

The MP143 on Kickstarter here: https://www.kickstarter.com/project...-salt-143mm-large-planar-hifi-in-ear-monitors

Hidizs official site: https://www.hidizs.net/products/hidizs-mp143-large-planar-magnetic-hifi-in-ear-monitors

As always, these links are non-affiliate.

To avoid being repetitive in my reviews, you can find all the info about how I create the reviews, equipment used, how I receive the products and how to interpret my reviews by visiting: About my reviews

DSC_5750.JPG


Intro…

Before even getting to the IEMs, I want to mention the collaboration of Hidizs with the WDC (Whale and Dolphin Conservation).

When I was first asked about reviewing the MP145 (the previous planar model from Hidizs), I was told (so were other reviewers) that they were collaborating with the WDC and that there would be donations from the MP145 going to the WDC.

As time passed, there was no confirmation on what these donations were and even WDC, when contacted, said that they had not received anything from Hidizs. The subject became very confusing and there was no clear answer for quite some time. Finally there was some clarity brought to the situation and an announcement was published on the WDC site (that you can find here).

So, when Hidizs reached out regarding the MP143, saying that they were once again collaborating with the WDC, my first question was would they be clearer this time? The answer was yes, that they apologised for the confusion around the MP145 due to it being their first collaboration but that the MP143 would continue to support the WDC education program in the same way.

Anyway, with that out of the way, on to the IEMs, as this is an audio review after all!

In the words of Hidizs, the MP143 promise to deliver “the same superior sound tuning as the MP145 but at a more affordable price”. The truth is that they were launched with a super early bird price of $79, which then increased to a limited early bird price of $99, with the regular price stated as being shown as $159. When the MP145 was released, the same tiers were $109, $119 and $199, respectively. So we are in fact looking at about a 20% reduction in price over the previous model.

So, the reduced price is there but do we give anything up over the previous model?

DSC_5843.JPG


Presentation…

The packaging is fairly similar to the MP145, only the way of presenting the included tips has changed. In the box of the MP145, these were presented on a large card with labelling to identify them, whereas, in this case, we get a little cardboard skewer. This is something that doesn’t bother me in the slightest, as the less packaging the better (even if it is stated as being ocean friendly packaging).

We do get less tips here also, with only 6 sets (in two types) being included, instead of the 9 sets in 3 types that we got previously. Once again, this is not really an issue for me as I just pick a set that works for me and stick with them for the review, maybe swapping them out after I have done my detailed listening.

The included cable is also a little simpler than the one included with the MP145, at least the balanced version that I received. However, that doesn’t mean the cable is bad. I praised the cable included with the MP145 but that doesn’t mean I am going to complain about this one. It is simple and, although it might not be my favourite cable, it gets the job done just fine.

DSC_5689.JPG


Build and aesthetics…

There is a clear similarity between the two models, however, they are not the same. While the build quality does seem to be of the same level, the MP143 is slightly smaller, slightly lighter and opts for a different design on the face plate.

While the faceplate is still “inspired by a whales tale”, it's more a simple stepped design than the raised shape of the MP145. I actually like this aesthetic and appreciate the fact that it is smaller and lighter, although it is still not a small or light IEM by any means.

However, the smaller size doesn’t work in favour of comfort for me personally. While the shells may be smaller, the extension of the nozzle is also less, making it more difficult to get a seal at first, at least for me. For some reason, I also find that the left IEM causes a pressure point on the top part in my ear, making it a little uncomfortable at first. This seems to go away after a while, so maybe it is just “new shoes” syndrome.

Sound…

All tracks mentioned are clickable links that allow you to open the reference track in the streaming service of your choice (YouTube, Tidal, Qobuz, Spotify, etc.)

So, the important part, how does the MP143 sound?

Well, it depends on the nozzle selected. Once again Hidizs have included 3 different nozzles to enable the user to choose their preferred sound (and give the reviewer 3 times as much work 😉 ).

Here is the graph of the 3 options in comparison to my usual preference target for reference:

graph%20(6).png


The obvious question is… how close is that to the MP145?

Well, here is the MP143 (Rose) in comparison to the MP145 (Red):

graph%20(8).png


Here is the MP143 (Silver) in comparison to the MP145 (Silver):

graph%20(7).png


And here is the MP143 (Red) in comparison to the MP145 (Red):

graph%20(9).png


You may have noticed that I have not compared anything to the Gold nozzles of the MP145, that is because the differences between the Silver and Gold on the MP145 were minimal (check out the MP145 review for more on that).

So, with all the squiggly lines out of the way, on to my subjective impressions.

Starting off with the Red nozzles, I am not a fan. While this tuning is becoming a regular lately and there are some sets with similar tunings that I really enjoy, I don’t find it works well with the MP143. Things come across overly blunted and focused on the low end. Rather than going into details and saying negative things, let’s move on to the other two nozzles.

There are a lot of similarities between the Silver and Rose nozzles, however, there is much more of a difference between them than there were between the Silver and Gold on the MP145.

Here the Rose nozzles give a little more focus on the lower end, with a more relaxed upper range, whereas the silver nozzles have more “bite” to them.

To be honest, I like both of the nozzle options and can listen to either of them but found that I spent more time with the Silver option, which is what my following opinions are based on using.

Using my usual “Chameleon” test, I find the lower notes to have plenty of presence and stay rather clean, although they do become a little excessive for me personally due to the boosted midbass range also. I don’t find the midbass range to be offensive, “Crazy” is not overly boomy nor fatiguing, but I do find that “Chameleon” is a little too much in this regard.

Speaking of “Crazy”, there is a nice clarity to the track, although the vocals can get just a little too spicy with the Silver nozzles, something that is tamed by opting for either of the other two options.

The midrange is well balanced in general although I do find that there is a slight lack of presence in the upper midrange. This is especially noticeable with female vocals, such as Sara K. in “All Your Love”, where there is a bit of a rounded effect to her voice in general.

This is not quite as noticeable with male vocals but is still there, such as Francesco Yates in “Sugar (Acoustic)”, where his vocals are clear but seem to be missing a little bit of brightness in those upper mids.

The same could be said with details in general, such as the intro to “All Your Love”, where the details are not quite as clear and also present that “rounded” sensation to them. However, speed is certainly not an issue, as the busy parts of “The Room” show.

Soundstage is not really something that stands out to me with the MP143, there is some space but it is not a sensation of a large soundstage, more of a reduced space where positioning is rather good for the limited space, as shown by “Bubbles”, where each of the balls is easily located. With “La Luna”, there is not much of a sensation of depth or width either, although there is plenty of separation between the instruments.

DSC_5676.JPG


Conclusion…

There are a lot of similarities between the MP143 and the MP145, although I would say that there is a noticeable difference in performance between the two sets. The MP145 comes across as more detailed, with more space, where the MP143 comes across as rounder and a more compacted presentation.

Saying this, I don’t think the MP143 is bad, far from it, I think it is a very good set of planar IEMs, I just don’t think it is a direct competitor for the MP145. At the current sub 100€ mark, I think you are getting a decent performing set of IEMs, that also offer you 3 tuning options and are quite capable of keeping up with fast moving and busy tracks. They are not the most detailed of IEMs but, again, they do have other things that they focus on, such as the bass, if that is your kind of things.

If you have the MP145, then I really don’t see any reason to look at the MP143. Saying that, if you buy the MP143, I also don’t think that there is such a significant jump up to the MP145 that it would be worth picking those up either. If you don’t have either and are torn between the two, ignoring the size and weight (which obviously puts the MP143 ahead), I think I would personally go for the MP145.

1000+ Head-Fier
Two Tenths Minus
Pros: Smaller size and lighter weight than its predecessor.
- Smoother, more relaxed and warmer tuning, free of sibilance and suitable for long listening.
- Deeper and more powerful bass.
- First half of the midrange more full-bodied and dense, more wall-of-sound feel.
- Relaxed upper mids, treble in tune, yet extended in the first two halves.
- Three tuning filters and 6 pairs of tips with different tuning properties.
- High level of construction.
- The red filter turns the MP143 into an IEMS for bass heads.

Cons: The sound is more nuanced, darker, less technical, separated and with less scene than its predecessor.
- The cable has only two strands instead of the four of its predecessor.
- Despite the smaller size, the projection of the mouthpieces is lower, making the insertion more shallow.
- I still miss a zippered case instead of a carrying bag.
Introduction

Hidizs has redesigned what has been one of its best models, the MP145 planars. The new model is called MP143 Salt. Its design continues to be inspired by whales, with a new 14.3mm planar driver and a smaller and lighter capsule, weighing only 8 grams each. The driver remains large and is called ‘FAST 2’. It has been customised by Hidizs and employs a fully symmetrical 7+7 N52H magnet design, which almost achieves 1 Tesla in magnetic space. Its diaphragm is nano-level to provide more information and dynamics. For the cable, the classic 2Pin 0.78mm interface has been used with a choice of two terminations: SE 3.5mm, BAL 4.4mm. Gold-plated connectors and high-purity, oxygen-free silver-plated copper conductors are used. Hidizs is still committed to include 3 pneumatic filters to offer 3 different tunings. These filters are in the form of screw-in mouthpieces that can be interchanged, as was the case with the MP145 model, with three colours: Gold (balanced sound), Silver (high frequency sound) and Red (low frequency sound). Finally, it continues its collaboration with WDC and comes in plastic-free packaging. Let's see what this new model can offer, which, at the time of writing, can be purchased for $99, while its official price is $159.

Packaging

The Hidizs MP143 comes in an eminently grey box whose dimensions are 134x108x50mm. The texts and engravings are gold-coloured. On the front side you can see a real photo of the capsule. At the top left is the Hidizs logo, in the upper right corner is the WDC logo and another logo indicating the size of the driver used. At the bottom, the model is presented in several languages. In the same way, but in white ink, the specifications cover the back side, also in several languages. At the bottom are the brand name, as well as the supplier and the logos of the certifications the product complies with. After opening the box, the capsules are encased in a cardboard mould made of multiple layers of black cardboard. It should be noted that no plastic is used in the packaging. There is a legend at the bottom with the name of the model and a slogan. On the top there is a white ribbon to lift this first layer. On the second layer there is another black cardboard box containing the rest of the accessories:

  • The two Hidizs MP143 capsules.
  • The silver-plated copper cable with BAL 4.4mm connector and 2Pin 0.78mm interface.
  • A set of three pairs of white silicone tips sizes SxMxL.
  • One set of three pairs of black silicone tips sizes SxMxL.
  • One pouch with flexible band closure made of black synthetic leather.
  • Transparent plastic box with 2 pairs of tuning filters (red and grey). The gold filter comes installed.
  • Instruction manual.
  • Card with the brand's social networks.

The silicone tips are strung on two cardboard hooks. But, to be purists, the filters come in a plastic container and the bag could have been made of cloth. On the other hand, my criticism is not in that sense, but that I would have preferred a zippered case and a slightly thicker cable, like the one in the MP145 model, which was 4-strand. On the other hand, the MP145 model had three different and complete sets of tips.

Construction and Design

The design has changed and Hidizs has strived to design a smaller and lighter capsule. They have succeeded, but it is possible that this is why they have had to reduce the size of the driver. The design retains that outer trapezoidal shape, but it is smaller in size, with a smaller circumference and thickness. There is also less weight, but the projection of the mouthpieces is not as long, something that influences the ergonomics in a negative way, at least in my case.
As I say, the capsule shape has 7 faces of varying lengths, just like its predecessor. The outer face starts with a sloping chamfer in the upper area, followed by a flat area where the brand name is written in white ink and the WDC logo. This is followed, towards the bottom, by a stepped pattern that simulates waves and/or whale baleen. The edge is narrower and the 2Pin interface is fully integrated into the capsule and consists of an oval translucent plastic plate containing two 0.78mm gold-plated holes. Next to it is a hole. The inner side is flat, smooth and inclined towards the mouthpieces, there is no ergonomic shape, no protrusions, apart from the rounded inclination towards the mouthpieces. The mouthpieces are part of the capsule. They start with a step and an initial diameter of 5.7mm. The threaded filters make up the crown of the mouthpiece and have a diameter of 6.2mm. The total length of the assembly is approximately 5mm. On the way to the nozzles, on this inner side, there is another hole.
The cable is somewhat simpler than the MP145s. Consisting of two single strands wound together, the conductor is still silver-plated, or at least silver, although the conductor is specified as high-purity oxygen-free copper. The sleeve of the gold-plated 4.4mm BAL connector is a matt metal cylinder. There is a polished engraved ring at the top, near the cable outlet, protected by a translucent plastic coating. The splitter piece is a smaller single cylinder, but of the same construction as the connector sleeve. The pin is a ring of the same style, the inner hole of which is too large to fit the cables tightly. The sleeve of the 2Pin 0.78mm gold-plated connectors are both metal cylinders with a recessed ring painted in red or blue, depending on the side of the channel. The style and colour is maintained on all metal parts of the cable. The cable has an over-ear guide made of the typical translucent plastic tube.
It seems that the goal of reducing the size and weight of the capsules has been achieved. The mouthpieces are different from those of the MP145 model and the cable is only made of 2 strands instead of the 4 strands of the previous model. This is something I don't understand, it seems a step backwards in the overall quality of the new model.

Adjustment and Ergonomics

It is true that the MP143 is smaller, lighter and thinner than the MP145. But the projection of the nozzles is shorter. This makes the insertion shallower and not as deep. If with the MP145 I got a shallow insertion that made the edges of the capsule barely rub against the parts of my ears, with the MP143 the integration is deeper and they fit tighter, without getting that floating effect that I did get with the previous model. It is true that the set is better adapted to the ears, but it has been more difficult to find the right tips, my classic big tips filled with foam have not worked, I have had to play with different variations of filling and size of silicone tips. It is true that the size and weight has been reduced, with the consequent ergonomic improvement that this entails. But the fit is a little more critical than what I get with the previous model. Maybe I'm special in that sense, but my ear morphology is what it is. So the new Hidizs MP143s are a little bit behind in the fit aspect compared to the previous larger and heavier model. And this fact can also be detrimental to the final sound, considering that the better the seal, the better the perceived sound, I have the feeling that I don't get that level in this new model. Likewise, the degree of occlusion and the feeling of isolation is also inferior to the MP145 model.

Sound

Profile


The difference in tuning between the MP143 and the MP145 is not very great, as can be seen in the graphs. But there are clear differences, especially from the upper mids onwards. The MP143s are deeper, with a slightly higher sub-bass, something that accentuates a purer W-profile, but also softer in the high end. The upper mids go into a trough while the highs are smoothed out a bit more. All of this contributes to a warmer and softer presentation, very much in keeping with the current trend of cutting the brightness of planar drivers. The MP143s with the Silver filter are somewhat closer to the MP145s with the Gold filter. With this filter, the MP143s accentuate the W-profile and slim down the bass and upper midrange. The sound becomes a bit punchier, more edgy, but also more transparent and clearer, losing some of the warmth it has with the gold filter. This is undoubtedly a very good alternative to restore some sparkle by losing some softness in the ambience, making the sound a bit more technical as well.
But the real revolution lies in the Red filter, which radically changes the sound of the MP143s, turning them into very close to level IEMS for Bass-Heads, much more polarised than the previous MP145 with the same filter. The upper midranges are depressed while the bass and sub-bass are obviously lifted. The profile becomes darker, although the treble doesn't change that much. It's the combination of a lot more bass and that clipped clarity area that loses transparency and makes the sound more opaque and dense. I would say that this filter is for experimenting, for special occasions and focused for bass heads.
To reduce my impressions in this review, my observations about the sound will be based on using the default Gold filter, whose sound is more balanced.

Hidizs MP143.png

Bass

The MP143s have a more emphasised sub-bass. In my opinion, this gives it a more pronounced sense of depth. It also feels darker, due to its warmer and softer profile in upper mids and upper treble. As a whole, the bass is big, broad, extended and dense. It is not overly textured and is more rounded and smooth in its presentation. That limits any sense of roughness or surface roughness. And that union of roundness and smoothness on its surface gives it a more rubbery, slightly springy appearance that makes it quite attractive, while accentuating its density and body.
In the very low frequency pure tone test, at the lower audible end there is a certain wave character above a more sensory or audible behaviour. As the frequencies get higher the naturalness and better behaviour comes to the fore and that comes quite soon. I wouldn't say that this is an exemplary bass in this respect, I would even say that it sounds musically speaking better than it behaves in this test. There is nothing critical about it, just that I was expecting a first tone with less wave character and more sensory. However, the translation to reality is good, implementing quite fast bases, with a high decay and very little aftertaste. This more rubbery character avoids dryness and gives it a greater extension. It all helps to recreate that sense of depth, darkness and density.
All in all, the MP143‘s bass is a little more elastic, rubbery, dark and deep than the MP145’s. I think the MP145's bass is drier, subtly a little more coloured, but more compact and more technical.

Hidizs MP143 12_r.jpgHidizs MP143 13_r.jpg

Mids

The midrange of the MP143s is warmer and denser, feeling somewhat more veiled compared to the MP145s with the same filter. This makes the male vocals more full-bodied, but also less explicit and informative. The softness of the upper mids makes them lose a point of sparkle and transparency, something that can be gained with the Silver filter. Still, that sense of warmth prevails. The density of this first part leans towards the low end, without the male vocals taking centre stage, thus building up that wall-of-sound feeling. The warmth and darkness influences the timbre of those voices, subtracting upper harmonics and framing that slightly more romantic sound, but also heavier, softer, but less detailed, less explicit and more blunt and rounded.
The result is repeated with the female voices: that feeling of softness and roundness persists, with a thicker and more controlled note weight. In MP145 these female voices are freer, cleaner, clearer and more exalted, also more detailed and with that more accentuated analytical level. The musical complexity is not as high in MP143, at least, it does not jump out as much as in MP145. As it is denser, the instrumentation becomes more intricate and the greater weight of the notes, especially of lower frequencies, overshadows the technical expressiveness of the midranges and they become less detailed, less transparent and more united. It is more musical, it is smoother, less harsh, free of sibilance, denser, with more body and weight. But it is also somewhat diminished in clarity and expressiveness. However, its technical skill persists, as well as the emotion of a midrange with great melodic richness.

Hidizs MP143 14_r.jpgHidizs MP143 15_r.jpg

Treble

Purely speaking, there are not so many differences in the high end of the MP143s compared to the MP145s, so that feeling of linearity persists, even somewhat corrected compared to the previous model. It is clear that all the previous more relaxed and softer tuning may influence the perception of a quieter treble, coming from a less vivid sound, but the energy level of the treble is still maintained. Perhaps, it is felt that the thickness of the high frequencies is a bit greater, that could explain the overall softer feeling in this range. The MP143's are less sibilant, but maintain that typical extension of their previous sibling, with no hollowness, displaying an adequate, natural and homogeneous timbre. They also maintain a somewhat reduced air area, something that is repeated in all three filters. However, the Silver filter provides a higher point in the first treble, adding a little more sparkle and liveliness to this beginning. The sound also seems to be a little freer, a little thinner, less rounded and more sparkling.
All in all, the treble remains balanced and extended in its first two parts, with a broad initial representation, a level of energy maintained that provides homogeneity and naturalness.

Hidizs MP143 16_r.jpgHidizs MP143 17_r.jpg

Soundstage, Separation

The MP143 has a smaller capsule and a subtly smaller driver. It also has no such opening on its outer face. Perhaps these details and a few others, as well as its warmer, darker and deeper tuning, may explain why the soundstage does not appear as large as in the previous model. Although it is wide and quite deep, it does not have that expansive, gaseous, extended feel of the MP145s. Its greater density, greater note weight and thickness give it a larger wall-of-sound feel, but a more restrained and tightly packed soundstage. There is a noticeable representation on all three axes, but it doesn't come across as surrounding or volatile. Separation is good, but not as transparent or obvious. Thus, detail is not as evident, nor is it as explicit. It has good representation of macro and micro detail, but not high expressivity, offering a softer, more relaxed and calm informativeness, more suitable for long, rich listening.
The image is well positioned, feeling homogeneous but well exposed. There is a good level of layering of layers, elements, instruments and notes. But that denser, darker feel can prevail in certain musical situations, detracting from nuances and a sense of multiple layers.

Comparisons

Hidizs MP145 Gold Filter


Throughout the review I have compared both models. In my opinion the MP143s are a warm, smooth, deeper, slightly darker, also denser and more compact version of the MP145s. The MP145s have a less powerful and present lower end in the mix, subtly more coloured, but drier and faster. The midrange is more transparent, explicit, clear, bright and separated. This gives it a more analytical, expressive and informative character, but also more piercing. The highs are fairly homogeneous in both, but the MP145s have finer notes. The stage and separation is greater in the MP145s, while the MP143s offer a more homogeneous wall of sound.
Overall, the MP145s are more precise, more technical, wider, extended, more transparent and separated.
Surprisingly, the MP145s are somewhat easier to move than the MP143s.

LetShuoer S12 Pro

When talking about planar IEMS I always have two of the most famous models in mind: the 7Hz Timeless and the LetShuoer S12. I haven't had the pleasure of trying the first ones, but I have two versions of the second one, the standard and the Pro. There are also some special editions, like the Z Reviews Gold special edition and now, due to the eighth anniversary of the brand, it seems that there is a special edition of the S12 with a titanium outer face.
The version I am going to compare with the MP143s is the Pro, as their similarity in frequency response is superior. You could say that the S12 Pro version is warmer than the original, with a more emphasised sub-bass and somewhat more restrained upper midrange and first treble. And that is something that is very much related to the differences between the MP145s and the MP143s. That's why I think this comparison is very appropriate.
The S12s could be the kings of planars in small capsules, it seems unbelievable how Letshuoer has managed to integrate such large planars, remember 14.8mm, in such a small and comfortable capsule. In my opinion there is one drawback related to this aspect and that is that the S12 Pro have a denser sound due to more congestion. The feeling of a slightly darker wall of sound is more perceptible in the Letshuoer. Subtly easier to move, the S12‘s cable is modular with all three presentations, with two strands thicker and stiffer than the MP143’s. They come with an oval zippered carrying case that I miss so much on the Hidizs. It also comes with three types of tips, two of them made of silicone and another set of foam.
With such similar frequency responses, the profile is very similar. The bass of the MP143s is somewhat darker, more elastic and rubbery than that of the S12 Pro, which seems a little drier and more restrained, but with a little more colour. Thus, the S12 Pro give the impression of a more technical bass. The behaviour in the very low-frequency pure tone test is very similar indeed. Perhaps the MP143s sound less wavy and more realistic, which implies a better sonic refinement in the bass.
In the midrange there is a feeling of fuller and warmer male vocals in the MP143s, also somewhat closer and denser. This gives them a touch of exuberance, something that also rubs off on the instrumentation in this section. The female vocals feel a little more sparkle and liveliness in the S12 Pro, something that gives them a slightly more natural and realistic timbre, because they don't feel as soft or muffled as in the MP143s. The note weight and thickness in both IEMS is similar, but that slight superiority in energy in the upper midrange and early treble gives the S12Pro's a higher point of transparency, clarity and level of detail exposure. Things become much more equal when the MP143s are fitted with the treble filter. It is then that you feel a superior resemblance between the two IEMS.
In terms of soundstage the MP143s seem a little more relaxed, a little more vaporous. Whereas the S12 Pro's are more overwhelming, more solid, with that wall of sound that becomes more frontal, but also wide. The impact is carried by the S12 Pro, but there is a little more air and smoothness in the MP143s, offering a lower level of demand and a more bearable sound. The S12 Pro's are a little more explicit, precise and technical. But, as I say, the treble filter evens things out a lot in those respects, except for that perception of density and wall of sound.

Conclusion

The Hidizs MP143 Salt is a planar IEMS with a powerful, deep low end, a warm, subtly dark, yet smooth, secure and homogeneous profile. Within a musical naturalness, its note weight is thicker, but it possesses richness, great dynamics, as well as an organic, analogue, dense, pleasant and harmonious sound. The Hidizs MP143s are in that trend that enhances the sub-bass and attenuates the upper mids, achieving that more relaxed sound, free of sibilance, tasteful, temperate and moderate on top.
On the other hand, Hidizs has reduced the size of the capsule and also its weight, perhaps two of the main drawbacks of the MP145 model.
Launched with a starting price of $79, at the date of publication of this review they sell for $99, when the final price seems to be set at $159, just the same as its predecessor, the MP145.
In my personal opinion, there are differences in favour of the MP145 (better technique, precision, greater transparency, separation and scene). But this is just a personal opinion. Maybe that tuning with more bass, warmer and smoother feel, as well as a smaller capsule size and weight than its predecessor, are a clear advantage over that first Hidizs planar model. What is certain is that, without a doubt, this is a great alternative within a positive path of the brand itself and a tough competition under $100.

There's something undeniably refreshing about the Hidizs MP143 Salt. It's more than just a pair of earphones; it’s a statement. A commitment to both audio excellence and environmental responsibility. By partnering with the Whale and Dolphin Conservation (WDC), Hidizs has transformed a product into a purpose. It's a testament to the belief that even small steps can create a big impact.

The MP143 Salt is a tangible embodiment of this philosophy. From the no plastic packaging to the design, every element whispers of the ocean. The name itself, a tribute to the iconic humpback whale "Salt," is a poetic touch that connects us to the heart of the project. It's a product that invites you to listen not just to the music, but to the story it carries.


27.jpg

26.jpg


The MP143 isn’t just a scaled-down version of the MP145; it’s a distinct product with its own unique personality. Hidizs has taken the strengths of the MP145 and fine-tuned them, resulting in an IEM that feels both familiar and refreshingly new.

Priced competitively, the MP143 enters a market full of options, but it’s not just another face in the crowd. It’s more like a sleek, agile shark, poised to make a real impact. But the big question is: does it have the bite to match its bold presence? Let’s delve into the details—exploring the sound quality, comfort, and overall experience—to see if the MP143 truly lives up to the hype.

Design/Build Quality:

Like the MP145, you’ll notice that the materials and finishing are on par with it bigger sibling, which is to say, top-notch. The MP143 carries on that legacy, but with a bit of a twist—it opts for a more understated look, slightly scaled down in size yet still elegant in design.

One thing that stands out about the MP143’s design is the lack of air vents on the faceplates. This is a deliberate choice that gives the MP143 a distinct and sleeker look without the bulging design where the vent is located on the faceplate of the MP145. The design still echoes the whale skin motif, which I find particularly striking. In my version (Silver), the pattern really pops, It’s the kind of design that makes these earphones as much of an accessory as they are a piece of audio equipment.


22.jpg

21.jpg


Even though the faceplates are vent-free, the MP143 isn’t completely sealed off. It features two ventilation holes—one on the inner side near the nozzle and another near the connector. These are well-placed to maintain sound quality without disrupting the sleek, minimalist aesthetic.

As for the size, I initially thought the MP143 might be on the smaller side, but in reality, the difference is minimal. The shape is more ergonomic, the design is snug and secure, but if you have more petite ears, you might still find them a bit challenging to wear for long periods but personally i dont have fit issues on the bigger mp145 and on the sleeker mp143.

All in all, the Hidizs MP143 strikes a nice balance between style and function. It looks great, feels solid, and is designed to perform well.

Sound impression:

The Hidizs MP143 borrows a lot from its predecessor, the MP145, but with its own unique spin, especially when it comes to tuning, you’ll notice that the MP143 follows the 2019 Harman path closely but with a few tweaks that give it its own character. The sound signature leans towards a warm/neutral profile, with some variation depending on which nozzle filter you choose. Personally, I gravitated towards the Silver nozzles, which, to my ears, offered the most details and clarity bacause of the slight treble bump and extension yet still retains the bass and warmth.

What struck me first about the MP143 was its tonal character—a slightly bassy U-shape with just the right amount of energy in the upper frequencies. It’s a sound that blends smoothness with a touch of crispness, creating a listening experience that feels both cohesive and dynamic. The transients are impressively fast, but not so much that the music loses its natural texture and timbre.


15.jpg

14.jpg


Despite its price point, the MP143 punches above its weight in terms of detail retrieval. You get a clear, hard-lined attack with a snappy decay, which really makes the MP143 stand out, particularly on faster and more complex tracks. It’s here that the MP143 shows its lineage, echoing the performance of the MP145..

The overall sound has a slight recession in the lower midrange, giving it a leaner, yet still lush, note weight. This isn’t a set that’s going to overwhelm you with energy—it’s more refined, offering a mellow yet detailed listening experience.


13.jpg

9.jpg


When it comes to drivability, the Hidizs MP143 doesn’t demand much to get going, but like every planar iems i own it definitely appreciates a bit of extra power. With an impedance of just 17 ohms and a sensitivity of 103dB, the MP143 is fairly easy to drive, even with less powerful sources. You can plug it into your smartphone or a basic DAC, and it’ll sound acceptable and good—no doubt about it.

But here’s the thing: like its sibling, the MP145, the MP143 really starts to shine when you feed it more power. It’s as if the sound opens up, delivering a richer, more dynamic listening experience. It’s not that the MP143 can’t perform with less power; it can. You’ll still get a solid listening session, but you might miss out on some of the finer details and that extra layer of depth that makes planar sets like this one so captivating.



6.jpg


What’s also interesting about the MP143 is how much it responds to different sources. I found that it’s more sensitive to source pairing than most IEMs. When I paired it with sources that leaned towards a more dynamic, neutral sound, the MP143 really came to life. The tonality of your source can make a noticeable difference, so it’s worth experimenting to find what brings out the best in these earphones.

In summary, while the MP143 is easy to drive, don’t be afraid to give it some extra power and choose your source carefully. Doing so will reward you with a listening experience that is more vivid, dynamic and engaging, allowing the MP143 to truly show what it’s capable of.

Bass:

The bass on the Hidizs MP143 is where this iems endearing character shines just like its bigger sibling. There’s a decidedly obvious presence that hits with authority, particularly in the sub-bass region. The rumble is intense, creating a sense of depth that’s almost tactile, midbass in smooth warm and well textured and has the same punch and slam of its bigger sibling.

Comparing to the MP145, the bass here is more substantial, yet it doesn’t quite reach the same level of quality. The MP145 had a way of dissipating pressure through its faceplate holes, making the bass feel more expansive and probably it sheer size fo the shell contributes to the flowing low frequency it porduces. On the MP143, the bass is more concentrated and can bleed slightly into the mids, but it remains impressively controlled for a planar driver.

Sub-Bass: Deep and Resonant ( depending on the eartip you will use)

The sub-bass on the MP143 deserves special mention. It reaches convincingly low, delivering a resonant, textured rumble that you can feel as much as hear. This is particularly impressive for a planar IEM because i heard that its really hard to tune a planar driver to produce such low rumble that is akin to a dynamic driver, which traditionally most planar driver i tried struggles to replicate the depth and physicality of dynamic drivers in the sub-bass region. The MP143, however, comes close, with a sub-bass that’s heavy, mean, and thoroughly enjoyable. It’s the kind of low-end that makes you feel the music in your bones, adding a layer of visceral impact to tracks that demand it.

Mid-Bass: Clean and Controlled

Moving up to the mid-bass, the emphasis is slightly less pronounced, which helps prevent the sound from becoming muddy. The transition from sub-bass to mid-bass is handled with excellent coherance finesse, maintaining good note definition and speed. While the MP143’s mid-bass isn’t as punchy or refined as some of its competitors in the price range, it’s still a solid performer. It provides the necessary warmth and lushness to the lower midrange, enhancing the overall richness of the sound without overwhelming the other frequencies.

Mids:

The midrange on the Hidizs MP143 is where things start to get interesting. There’s a slight recession in this area, but it’s not enough to push vocals or instruments into the background. Instead, the mids come across as warm, rich, and slightly laid-back, with a linear style that adds a sense of coherence to the overall sound. The planar driver does a commendable job of maintaining separation and clarity, ensuring that vocals remain audible and clear even when the bass gets heavy.

the tonality and timbre is natural with lifelike vocals that reproduces the sound with emotion and vivid details particularly with the right source and tips. I found the lower midrange to be particularly pleasing, with a nice balance of warmth and weight that gives male vocals a sense of authority and presence and the female vocals with energy and clarity.

Upper-Mids:

The upper-midrange is where the MP143 starts to regain some of the sparkle lost in the lower mids. Female vocals have a juicy, well-defined quality, particularly when using the Rose Gold or Silver nozzles and wide bore tips. Instruments like acoustic guitars and violins come through with a satisfying amount of bite and shimmer, adding a touch of brightness that contrasts nicely with the warmth of the lower frequencies. The result is a midrange that feels dynamic and lively, even if it’s not the most forward or aggressive. When compared to the mp145 the mp143s upper mids has a slight brightness and sparkle that extends to the lower treble with smooth coherent transition.

Treble:

The treble on the Hidizs MP143 is balanced and smooth, with enough clarity and resolution to keep things interesting. It’s not a treble-heavy IEM, so treble-heads might find it a bit too laid-back for their tastes. However, for those who prefer a more balanced sound, the MP143 delivers in spades. There’s just enough sparkle and air to add a sense of openness to the sound, without making it harsh or fatiguing.

Switching to the Silver nozzle enhances the treble even further, bringing out more micro-details and adding a touch of brightness that lifts the entire sound signature. This makes the MP143 feel more refined and almost at par in performance to the MP145, though the latter still has the edge in terms of soundstage and overall definition.

Soundstage and Imaging: Above Average for the Price

The soundstage on the Hidizs MP143 is not as huge as its bigger sibling but it’s well-developed, particularly in terms depth. There’s a decent sense of space and separation, though it doesn’t quite match the expansive soundstage of the MP145. Imaging is precise and accurate, with good separation and layering, typical of planar drivers. It’s an above-average performance for a $79-99 IEM, though not groundbreaking.

Nozzle Filters: Fine-Tuning the Experience

One of the features of the MP143 is the interchangeable nozzle filters, which allow you to fine-tune the sound to your liking:

- Red (Bass): This nozzle enhances the low frequencies even further, at the expense of detail and brightness. It’s a good option if you’re sensitive to high frequencies, but I found it to be a bit too much and sometimes overwhelming, as it takes away some of the clarity and sparkle that the MP143 needs to balance out its bass-heavy nature.

Rose Gold (Balanced): A good compromise, this nozzle dampens the treble slightly, making it less aggressive while also taming the bass particularly the subbass boominess and tighter midbass maintaining a more balanced sound. It’s useful if you find the highs a bit too much.

- Silver (Treble):This is where the magic happens. The Silver nozzle restores the balance between bass and treble, adding more air, detail, and clarity. It’s the best option if you want to bring the MP143 closer to the performance of the MP145, making it the definitive choice for those who prefer a more refined sound, this my choice of nozzle paired with divinus wide bore tips.

Conclusion:

The Hidizs MP143, while not an outright upgrade to the MP145, still holds its own remarkably well. Sharing the same DNA, but the MP145 remains superior in almost every aspect. However, this doesn’t diminish the MP143’s appeal. It offers a sound and performance that closely follows its larger sibling, despite its smaller shell and slightly reduced planar driver. What’s more, it’s priced at nearly half the cost of the MP145, yet it retains the same thoughtful design, premium quality, and tonal richness.

If you’re still in the market for a planar IEM that delivers substantial bass, warm mids, and balanced treble, the Hidizs MP143 is definitely worth considering. It’s a well-rounded performer that punches above its weight, making it an easy recommendation for anyone seeking a quality planar IEM with addictive bass. Additionally, with every purchase, a portion of the proceeds goes to the Whale and Dolphin Conservation (WDC), supporting the protection of marine mammals and the ocean ecosystem. Even if you already own the MP145, the MP143 is a worthy addition to your collection and is a feel good purchase considering the noble cause behind it.

● Even in the SILVER TUNING FILTER NOZZLE setting, sibilance is kept under control and not a hint of harshness.
● Somehow it projects a roomy sound/speaker stage within my aural perception.
Cons: ● Despite its smaller form profile compared to MP145, it is still on a large size that a small-eared size individual should take notice of.
● Well, planar magnetics…. it still needs more power output for proper amplification.
● Relatively less airy compared to other planar sets.
● Not a tuning profile for adherent neutral heads.
● Stock cable with no modular termination plug feature.
● Wishing for better layering and resolution capability, at least on par or an improvement over the MP145 but it wasn't the case in this regard.

Salt is one of the important minerals in the world as it is a very essential ingredient that affects all living species and even inanimate ones from the functions of the vital organs in the body up to industrial and culinary usage. It is said that around 97% of all water on Earth is saline in which the majority of those aquatic bodies are seas and oceans, and the marine species are thriving in those environments including cetaceans.

It also happens that this is the name of a female humpback whale based on the Stellwagen Bank found within Massachusetts Bay, and she was also known as the “Grand Dame” as she is also the matriarch of certain pod of humpback whales in the area. Humpback whales are known for their distinctive whale song that ranges from 20Hz - 31kHz that its lowest frequency can travel and reach up to 20 miles.

HIDIZS
as an audio company has its own merit that they are one of the most consistent ones out there in regards to product releases with some good value on it for audio enthusiasts who seek audio products at reasonable price. Their MP145 earned some high regard status in the audio community as one of the highly sought-after planar IEM sets around in the audio market that it was able to turn a tide on the Battle of the Planar IEMs on their own favour, and to think that the MP145 still have the ball on their court until now.

20240817_165754.jpg


And what I have here is a more affordable successor model, the HIDIZS MP143 SALT and like the MP145, this is still a collaboration between HIDIZS and the nature conservation group, WDC (Whale and Dolphin Conservation). WDC is known for their advocacies for raising awareness on protecting some aquatic mammals in the ocean like whales, dolphins and porpoises as they are one of the main factors on preserving marine biodiversity ecosystems.

20240817_170836.jpg
20240817_170842.jpg


Like its predecessor, The MP143 utilises a planar magnetic driver technology as its main transducer encased in a metal alloy shell structure. It uses a new generation 14.3mm planar magnetic driver in which HIDIZS claims that they did some tweaking and implementation on it like using newer generation of of neodymium magnet with an improved design and using a new type of thin layer of diaphragms for resolution capability, more accurate and promises better dynamic range while having some efficiency on its power output requirement.

20240817_170731.jpg


The driver was then enclosed in a CNC-milled aluminium alloy chassis in a trapezoid-like shape outline in a large size profile. Its faceplate has some grooves inspired by the baleen part of the whale which could be a design blueprint to all HIDIZS’ MP series. It has some vent holes used for escaping some excessive air pressure generated by its planar magnetic driver and like all current HIDIZS sets, it has its detachable nozzle system for more tuning options and continues on implementing a 0.78mm connector as its interlocking mechanism.

20240817_170709.jpg


The HIDIZS MP143's stock cable is a 2-core high purity Oxygen Free silver-plated copper cable with a gold-plated 4.4mm balanced termination plug on its end, you can choose another type of termination plug, the 3.5mm single ended upon purchasing. The cable quality is quite supple and has some entangled-resistant and there's not a hint of microphonics on it.

20240817_170743.jpg
20240817_170750.jpg


While it appears that the shell chassis is large and relatively angular in its contours, in my medium-size ears, it rests well into my lugholes without any issues even in my long listening session. It has a good passive noise isolation that it was able to block external noises from the outside surroundings.

20240817_170055.jpg


On how HIDIZS was able to come up on the product packaging of MP143, it seems that they are keen on environmental conservation on how they packed it up along with its inclusions as they uses less plastic while the majority of the materials are biodegradable that can be easy to recycle. The square packaging box is still bulky but it offers a quantitative amount of contents.

20240817_170524.jpg


Here are the following contents we can find inside of MP143's packaging box:
  • Pair of HIDIZS MP143 SALT IEM transducers.
  • Stock cable
  • Storage pouch
  • Pair of Pneumatic Sound Tuning Nozzles (RED)
  • Pair of Pneumatic Sound Tuning Nozzles (SILVER)
  • Three (3) pairs of balanced bore silicone ear tips of different standard sizes (BLACK)
  • Three (3) pairs of wide bore silicone ear tips of different standard sizes (WHITE)
  • Postcards, user manual and warranty card.
20240817_171023.jpg
20240817_171017.jpg


While it appears that MP143 can be driven by devices in normal gain mode, we will notice that it has an apparent inadequate amount of dynamics and sounds a bit lethargic due to the complex structure of planar magnetic driver that requires more power output to deliver a full range sound.

20240819_181112.jpg
20240725_051524.jpg


As for tonal profile aspect, due to its detachable nozzle system, HIDIZS offers three types of distinctive tuning curve which aligns with V to U-shaped sound signatures.

Hidizs_MP143.jpg

(FR graph was provided by @baskingshark , credits to his effort)

These are the following tuning nozzles with their brief tonal profile.

ROSE GOLD TUNING NOZZLE MODE - The most balanced sounding among the three, it has a U-shaped sound profile with warmish-balanced tonality.

RED TUNING NOZZLE MODE - The warmest sounding set within the three tuning filter nozzles as it also has an uneven U-shaped sound signature.

SILVER TUNING NOZZLE MODE - While it has a U-shaped sound profile, it is brightest sounding among them as upper-mids and presence section of high frequency is noticeable accentuated.


LOWS/BASS:

ROSE GOLD TUNING NOZZLE


The bass response of this tuning mode appears to have a well-balanced presentation on both parts of the bass region. There's a good sub-bass presence as it has some rumbling and reverberation coming from sub-bass focus instruments like synthesisers, drum machines and low tuned guitars and bass guitars. While the mid bass has an adequate texture on its note weight enough to give some fullness on some bass-clef instruments and deep male vocals.

Instruments:

Bass guitars - rasping and resonant sound.
Double basses - rasping and a bit broader sound compared to bass guitars.
Bass trumpets - full sounding with dark timbre.
Bass kick drums - full and thudding sound.

Vocals:

Basses & Bass-baritones - both have good depth, weight and dark timbre on their vocals to give that dusky and dense sound characteristics.


RED TUNING NOZZLE

Compared to the ROSE GOLD TUNING NOZZLE, this setting apparently has more texture and weight that makes the bass response even more fuller, authoritative and impactful but at the expense of noticeable bass bleeding that muddles the midrange a bit. While there are perceived rumbling and reverberations generated by sub bass-focus instruments, the mid bass has a well-bodied texture that is fuller and a tad boomy sound on some bass-clef instruments.

Instruments:

Bass guitars - weighty and earthy sound.
Double basses - heavy and sombre sound.
Bass trumpets - it has a fuller and darker timbre.
Bass kick drums - pounding and gloomy sound.

Vocals:

Bass & Bass-baritones - they sound more heftier with deep rumbling resonance with a darker timbre.


SILVER TUNING NOZZLE:

Among the tuning nozzle modes, this setting has a tighter and a tad leaner but retains its incisiveness on its overall bass response. It has a sub-bass presence as I definitely felt those reverberations and rumbling sounds coming from low tuned bass guitars, synthesisers and drum machines while its mid-bass seems a bit attenuated and leaner texture on some instruments and male vocals note weight.

Instruments:

Bass guitars - rasping and resonant with a tad hollowness in their sound.
Double basses - they sound menacing but also sounds a bit mellow.
Bass trumpets - it has that mighty sound but it has less darker timbre and lean sounding.
Bass kick drums - thudding and rumbling sound albeit they have less fuller sound compared to other tuning nozzle settings.

Vocals:

Bass & Bass-baritones - they sound less heftier with deep rumbling resonance with a darker timbre.


MIDRANGE:

ROSE GOLD TUNING NOZZLES


The midrange presentation of this one appears to be a bit recessed on its overall frequency range spectrum but it still retains a balanced texture, warmth and sufficient clarity in this particular frequency part. Both vocals and instruments somehow sound natural with some added colouration on their timbre.

Male Vocals:

Baritones - smooth with ample lushness on their voices.
Tenors - brassy with some metallic sound on their vocals
Countertenor - tender and smooth sound.

Female Vocals:

Contralto - smokey with some ample richness on the vocals
Mezzo-sopranos - sounds coppery and expressive.
Sopranos - creamy with lustre sound on them, excellent on dramatic and spinto types of sopranists.

Instruments:

Strings


Cellos - they sound sensuous and mellow.
Guitars - balanced and midrange-y sound on their strings.
Violins - full yet solemn sounding on every motion on its bowstrings.

Brasses

Trumpets - metallic and rounded sound
Trombones - they also have these metallic and “heroic” sounds.
Horns - mellow and velvety sound.

Woodwinds

Piccolos - clear yet sounds a bit eerie.
Concert flutes - mellow and graceful sound.
Clarinets - warm and round sounding.
Saxophones - mellow and velvety sound.

Percussions

Tom-toms - warm and resonant sounding.
Snare drums - hard and penetrating sound.
Field drums - full and sonorous sounding.
Kettledrums - substantial and rumbling sound.

Pianos - it has a mellow, rich and rounded sound.


RED TUNING NOZZLES

Due to bass bleeding that smudges across other frequency sections, It adds even more warmth on the midrange to have a more dense and lushness on some vocals and instruments but at expense of clarity and energy. This is the warmest and coloured midrange tuning among the three tuning filter nozzles.

Male Vocals:

Baritones - rich, steely and booming voices in which dramatic, kavalier and noble baritones will sound more fuller and deeper in this tuning setting.
Tenors - brassy, rich and too warm but that loses some of its bright tone, dramatic tenor, heldentenor and spieltenor.
Countertenor - too warm and velvety sound.

Female Vocals:

Contralto - lush, strong and richness on its chesty voice.
Mezzo-sopranos - musky and too smooth that it loses some of its intensity.
Sopranos - due to its too warm sound, it is unable to project shimmer and energy in which this type of vocal will sound better.

Instruments:

Strings


Cellos - weighty and thick sounding.
Guitars - too warm and buttery sound with some rich notes on every strum on its strings, sometimes a bit dark sounding
Violins - muffled and austere sound.

Brasses

Trumpets - too dark and too rounded sounding
Trombones - powerful with darker timbre and more full sounding.
Horns - warm and muffled sound.

Woodwinds

Piccolos - too dull and too linear that it doesn't have a bright and brilliant sound.
Concert flutes - dull and overly mellow sounding.
Clarinets - sounds rich and dark.
Saxophones - very warm and earthy sound.

Percussions

Tom-toms - inordinately warm and resonant sounding.
Snare drums - less bright and a bit boomy sound.
Field drums - fuller and more boomy sound
Kettledrums - dull and booming sound.

Pianos - too mellow that it sounds too dull and lethargic.


SILVER TUNING NOZZLES

The midrange of this one is noticeable a tad notched on its overall presentation and leaner on its note texture compared to RED TUNING but this one will sound more transparent, tidy and clear with sufficient energy for projecting some types of vocals more forward but at the expense of less warm sound. Female vocals and some instruments like strings and woodwinds will have some added brightness to sound more energetic and crisp.

Male Vocals:

Baritones - loses some warmth and lushness while retaining its smooth characteristic.
Tenors - spicy and dazzling voices. Good for leggero, lyric and spinto types of tenors.
Countertenor - fiery and tender sounding.

Female Vocals:

Contralto - less hefty that it loses some deep husky and rich sound on their chesty vocals.
Mezzo-sopranos - glowing and fiery sound on their voices.
Sopranos - Gleaming and silvery sound, good for coloratura, lyric and soubrette soprano types.

Instruments:

Strings


Cellos - weighty and thick sounding.
Guitars - too warm and buttery sound with some rich notes on every strum on its strings, sometimes a bit dark sounding
Violins - muffled and austere sound.

Brasses

Trumpets - too dark and too rounded sounding
Trombones - powerful with darker timbre and more full sounding.
Horns - warm and muffled sound.

Woodwinds

Piccolos - too dull and too linear that it doesn't have a bright and brilliant sound.
Concert flutes - dull and overly mellow sounding.
Clarinets - sounds rich and dark.
Saxophones - very warm and earthy sound.

Percussions

Tom-toms - less warm and resonant sounding.
Snare drums - bright and penetrating sound.
Field drums - majestic and expressive sound.
Kettledrums - dry and resonant sound .

Pianos - balanced to bright tone as it has a clean and brilliant sound but there's some tinniness on it for some reason.


HIGHS/TREBLE:

ROSE GOLD TUNING NOZZLES


It has a smooth and adequate brightness on its treble response. It has a mild elevation on its upper-mids then an even and smooth transition towards the presence treble section as if that there's nothing too peaky that might cause stridency and sibilance while having a good note definition and clarity on vocals and attack of instruments.

For a planar set, it has a rather moderate treble airy extension but at least it has an ample sparkle on it.

Instruments:

Cymbals - metallic and resonant sound.
Hi-hats - short undulating sound.
Celestas - sweet and lustrous sound.
Glockenspiels - bell-like and lustrous sound.

RED TUNING NOZZLES

While it has smooth treble response, it also has a tad darker and dull sound as it loses some brightness and resolution on this type of setting, The upper mids and some areas of presence treble sounds a bit subdued and veiled to some attenuation dips on that part that it has an inadequate clarity and definition for vocals and instruments.

The airy extension on the brilliance section seems lessened a bit and also less sparkling as it loses some harmonics on it.

Instruments:

Cymbals - soughing and undulating sound.
Hi-hats - short undulating sound.
Celestas - sounds a bit warm and too velvety.
Glockenspiels - a bit dampened to the point I can't describe it as lustrous.

SILVER TUNING NOZZLES

It has the brightest sound among the tuning filter nozzles as it has a shimmer and energy on its treble response. But to my surprise, it doesn't sound harsh and the sibilance was kept under control even though there are some perceivable accentuated upper mids and presence treble. It has a good clarity and definition for better resolution on vocals and better delineation on attack of instruments.

Apparently, the quantity level of its brilliance treble is almost similar with ROSE GOLD TUNING NOZZLES in terms of airy extension which is moderate but it has a sufficient sparkle.

Instruments:

Cymbals - metallic and resonant sound.
Hi-hats - short undulating sound.
Celestas - sweet and lustrous sound.
Glockenspiels - bell-like and lustrous sound.


SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

Depending on the tuning filter nozzles, it has a moderate to wide sound/speaker stage in lateral span, a good height reach and immersive depth within my aural perception in both ROSE GOLD and SILVER TUNING NOZZLES. The RED TUNING NOZZLE narrows the head stage size a bit but I can still classify it as moderately spacious.

While it projects an envelope stereoscopic imaging but it is less vivid that I'm a bit struggling on locating the exact position of vocals and instruments in a rather modestly layered soundscape and less spacing on each element in regards to separation aspect.

Coherency of its driver is excellent given the nature of a fast responsive performance of planar magnetic drivers as it is quite nimble and offers no distortion nor other phasing issues.

When it comes to resolution capabilities, depending on tuning filter tuning nozzles, both the ROSE GOLD and the SILVER TUNING NOZZLES are quite more resolving on micro-dynamics aspect as they have a clearer and sharper micro-detail retrieval while RED TUNING NOZZLES dampened it but gives more solid compression on macro-dynamics, it is like you gain some benefit but you will also lose some of its facets.


PEER COMPARISONS

LETSHUOER S08

  • LETSHUOER's latest entry-level planar magnetic IEM earphones, but it uses a smaller planar magnetic driver technology.
  • Like the MP143, this set also has a pill-shaped aluminium alloy shell chassis and it is also more compact that it can cater to all types of ear sizes.
  • The S08 is quite well-stacked with quality inclusions, from a circular TPE carrying case and a stock cable with modular termination plug.
  • This set has a warmish-neutral sound profile with some added bass-boost on it.
  • It also has a mid bass-focused bass response as it sounds more punchy and tactile, a fuller and well-balanced midrange to sound more natural in vocals and instruments while maintaining a clean and clear sound, and smooth treble response with less airy extension.
  • This one appears to be less technical compared to MP143 as it has narrower perceived sound/speaker stage, a rather concave-like stereo presentation but it has similar resolution capabilities (on MP143's ROSE GOLD TUNING NOZZLES mode) and a bit better on layering and separation.

KEFINE KLANAR
  • It has similar driver configuration with MP143 but it uses a smaller planar magnetic driver.
  • This one also has a metal shell chassis which is an anodising aluminium alloy.
  • It is also pretty well-accessorised with inclusions.
  • It has a V-shaped sound profile which makes it sound more coloured sounding as it has balanced-warmish tonality.
  • Compared to the MP143 (RED TUNING NOZZLE mode), it has a bit cleaner bass presentation while maintaining a deep and punchy bass response, a less warmer midrange but retains a lush and richness on vocals and instruments and a smooth a bit more airy treble response.
  • On technicalities, this one has a tad wider lateral span on its perceived head stage, a concave-like stereo presentation but it has a well-layered soundscape with good separation.

HIDIZS MP145
  • The MP143's predecessor and it uses a marginally larger planar magnetic driver technology.
  • Its metal shell chassis appears to have a bit larger profile and also a heftier one.
  • It has similar inclusions and accessories inside of its packaging box but this one has better stock cable.
  • This one also has a detachable tuning nozzle system as its main feature that offers 3 types of sound signature.
  • Compared to its successor (ROSE GOLD TUNING NOZZLES mode), it has a more sub-bass presence but it has less textured mid bass but still retains its punchy and tactile bass response, less recessed, clearer and more energetic midrange and a brighter and more airy treble response.
  • This one has better technical capabilities from a tad wider sound/speaker stage, an atmospheric stereo imaging with well-layered soundscape with excellent separation and perhaps more resolving in resolution capabilities.


As the second phase of battle of the planar sets is now commencing as there are some audio companies intend to enter this part audio market segment as it has a potential to be economically viable to audio enthusiasts who tend towards budget-friendly options. The HIDIZS MP143 is one of the best options in that regard as it offers a solid-build quality with well-accessorised inclusions and offers three types of tuning profiles for tonal versatility which is uncommon on its price segment.

Many audio enthusiasts have raised a main question whether this one is an upgrade to the HIDIZS MP145 or simply a sidegrade, I can say it's a no in both questions as this one has its own standard it terms of tuning that it won't simply match the tonal and technical prowess of the MP145 and second one was its asking pricing as HIDIZS has its own initiative on this product by providing a more affordable option for budget-minded audio enthusiasts who wants to hear the MP145 expenses but with some slight caveats.

The HIDIZS MP143 SALT is now available at HIDIZS Official Online Store. For those who are interested, I provided an unaffiliated link below.

Hidizs MP143 Salt Review

.
I would like to thank Hidizs for conducting this review tour of the Hidizs MP143 Salt Planar IEM for my local region, which, at the time the time of this writing, cost $79 US on a Kickstater early bird promo, and once the promo is done, the price will be $159 US. Hidizs, thank you so much for this opportunity to hear the MP143 Salt. After the tour is done, this will be raffled among us.
.
These are the features according to their website, which I copied and pasted, but kindly visit their website for more information:

The packaging is good and effectively done; it includes two sets of eartips, manuals, cables, and the IEMs themselves.
.
The size of the MP143 IEM is on the larger side, but it is slightly smaller than the legendary Hidizs MP145 planar IEM, its older sibling. However, there are no issues fitting it to my ear canals because the shape near the nozzle is slim, but I find it feeling a little weird near the 2-pin connector area, as they protrude slightly from my ears.
.

I used my usual sources for the sound evaluation: the Fiio M15s DAP and the Letshuoer DT03 dongle DAC with my phone. I also used the stock 4.4mm cable with the white stock eartips. The burn-in period was about 10 hours.
.
The Hidizs MP143 is not very sensitive but not very difficult to drive either; the Letshuoer DT03 dongle DAC drives it efforlessly, but I wouldn't recommend those smaller dongles for this.
.
The sound signature is mild V-shaped and on the brighter side, but it never became fatiguing. There is an upper midrange elevation, but it is not very obvious as it is obscured by the elevated treble and bass. Though it has a slightly bright treble, there is always a bass presence that prevents the MP143 from sounding lean. It has a very nice balance between bass and treble.
.
The soundstage is not the biggest in its price range but certainly above average, and I never felt claustrophobic. The imaging is also not the best in its price range but definitely above average. It has a fair amount of layering and separation, making it enjoyable to listen to without leaving you wanting.
.
It has loud, rumbly, and energetic bass, but it is not the tightest and most visceral I've heard. The bass is slightly rounded, and there is a hint of boominess and a lack of definition on songs with fast successive bass, but overall, it has a good souding bass that is very well balanced with the rest of the audio range.
.
The subbass has fast decay, so even though the graph shows excellent bass elevation, the subbass is not impressive in real life because of the fast decay.
.
The midrange is very neutral and very balanced between the male and female vocals, with very slight favoritism toward the female vocals. It has good details and note weight but is not very lush-sounding. It has fair elevation in the upper midrange but never gets shouty due to low distortion. Overall, the midrange is good.
.
The treble has a good amount of detail, extension, and air.
.

Versus Letshuoer Audio S08 (99 USD):
.
The S08 is a planar IEM that utilizes a 13mm planar with surround to ease its movement; it is slightly U-shaped in sound signature; it has more bass and upper treble; while the MP143 is more neutral. If you aren't comparing them side by side. The S08 has slightly better imaging, while the MP143 has a slightly bigger soundstage. I also noticed that the S08 has a cleaner background and slightly lower overall distortion. At the 79-dollar early kickstarter price, the MP143 is very competitive, but at the regular price of 159 dollars...ummm...
.
Versus Hidizs MP145 (150 USD):
.
The MP145 has a bigger soundstage, while the MP143 has better imaging. The MP143 can handle more power and go louder with lesser distortion. The MP145 bass is boomier; on the MP143, it's more controlled and tighter. The MP145 has a warmer midrange. The MP145 has more treble elevation, while the MP143 is more neutral in the treble. The MP145 has a bigger and grander presentation of the music. They have enough differences in sound presentation and signature that owning both won't feel redundant. I recommend the MP143 as a complementary IEM for the MP145.
.

Pros:
.
- I like the design.
- very good, balanced sound



.

Cons:
.
- the background is not the cleanest.
- I wish the regular price was lower.

Third-party eartips:
.
I tried it with the newly released Divinus wide-bore eartips, and everything has improved a little. The soundstage became slightly bigger, the imaging became slightly more defined, and the bass impact and tightness also improved. I highly recommend you spend some time experimenting with other tips with the Hidizs MP143. I'm not implying that the stock tips are bad; I'm just saying that other tips might make the MP143 sound even more to your liking.
.

Conclusion:
.
The MP143 is a nice-sounding planar IEM, and at the kickstarter price of 79 dollars or even at 99 dollars, it's a great value for money, and I highly recommend it, but I think the regular price of 159 dollars is a little high.
.
Happy listening! Cheers!

Hidizs x Whale and Dolphin Conservation (WDC): MP143 'Salt'​

Not Just The Design, It Actually Sings as Musically as a Humpback Whale!​

Hidizs has once again collaborated with the Whale and Dolphin Conservation (WDC) on their latest IEM Planar project. The design is more streamlined, inspired by "Salt," a female Humpback Whale. For those who don’t know, WDC is an organization focused on the conservation of whales and dolphins, educating the public not only about the whales themselves but also about their role in producing more than half of the Earth's oxygen.
The Humpback Whale, known for its "songs," inspired Hidizs to develop this IEM Planar, focusing on musicality and natural sound. Is that really the case? Let’s dive in.
Without further ado…Hidizs MP143 'Salt'
Note: For those interested in learning more about Hidizs x WDC, click the following link: [Hidizs MP143 Salt on Kickstarter](https://www.kickstarter.com/projects/hidizs/hidizs-mp143-salt-143mm-large-planar-hifi-in-ear-monitors?ref=a6rry1%E3%80%91)

==DISCLAIMER==​

All impressions are based on my usual setup (listed below). If there are differences in sound impressions, they are likely due to subjective differences in our ears, defective units, or the source used.
All my impressions and reviews are subjective, based on the belief that "only my savings can lie, but reviews must be honest." Agree? Fine. Disagree? Fine. I review because I want to and because I enjoy it, not because I need to.
Important!! I recommend auditioning for yourself, just in case my ears need an ENT specialist, or maybe yours do (haha).

==MY DAILY DRIVER==​

IEM:
Symphonium Crimson; Sennheiser IE 900; Empire Ears Legend X; Sound Rhyme SR8
DAC:
Fiio Q15; Chord Mojo 2
DAP:
HibyDigital M300; Hiby R4
Cable:
Effect Audio Eros S; Verus Lavender 6; Liquid Links Conti; Effect Audio Ares II
Ear tips:
Eletech Baroque; Spinfit W1 Premium; Azla Sedna Crystall; Penon Liquer; JVC Spiral Dot++

==Unboxing==​

Continuing the Hidizs x WDC commitment to whale and dolphin conservation, this is also reflected in the IEM’s packaging, which is made from recycled cardboard. The accessories include:
  • The IEMs themselves
  • OCC Copper 2-braid cable with 2-pin connectors
  • Ear Tips
  • Carrying Pouch
  • 2 pairs of Nozzles (along with the ones pre-installed on the IEMs, making a total of 3 pairs)

IMG-20240721-WA0028.jpg

==Fitting==​

Made from CNC Anodized Aluminum, the IEMs feel sturdy yet lightweight. However, they are very prone to scratches due to friction on the IEM body. Despite being slightly smaller than its predecessor, I didn’t notice much difference in fit due to my larger ears. Finding a comfortable fit was challenging at first; I thought the short nozzles with slightly above-average diameter were the issue, but they weren’t. The main issue was the bulbous shell, particularly below the nozzle, which made it difficult to fit securely in the ear without some pressure. Additionally, the cable placement causes the IEM to feel vertically elongated, extending beyond the ear cavity, resulting in an imperfect fit for the ear hooks. The only solution is to ensure the ear tips are snug and press the IEM in deeper for a better fit, while ignoring the floating ear hooks.

==Sound Impressions==​

Note: Base testing was done with Fiio Q15 and Divinus Velvet Wide Bore Ear Tips.
Note: There are 3 different nozzles that can change the sound:
- Gold Nozzle: Balanced
- Silver Nozzle: Treble Improved
- Red Nozzle: Bass Improved (my favorite)

IMG-20240824-WA0041.jpg

Bass
- Gold Nozzle:
Modern planar drivers have really improved in bass performance. The sub-bass is airy with a long rumble, has just the right impact, and is engaging. This IEM sounds great with any track. The bass has a similar engaging power, with just the right depth and enjoyable speed for any genre. Some might find the bass a bit too relaxed as it lacks a punchy quality but still has good power. If that’s the case, switch to the Red Nozzle.
- Silver Nozzle:
Similar to the Gold Nozzle, with minimal differences except for reduced low-frequency power compared to the Gold Nozzle.
- Red Nozzle:
The impact of the bass and sub-bass feels deeper than with the other nozzles, with greater power than the others. The rumble and punchy quality are fun, adding to the immersive soundstage without causing ear fatigue from excessive punchiness, etc.

Mid
- Gold Nozzle:
This is clearly the selling point of this IEM. With slightly forward vocal positioning, it delivers just the right notes for both male and female vocals—neither dry nor wet, airy without sounding thin. There is no sibilance or shoutiness; high-tone male and female voices sound engaging with just the right amount of power without feeling dry. However, the upper midrange to treble feels unclear, making snare drum crunch sound piercing and causing sibilance in some tracks.
- Silver Nozzle:
Almost no difference, except for more noticeable sibilance in the upper midrange. For those who don’t like harshness, even the midrange already has a slightly sharp "sss..." sound.
- Red Nozzle:
Similar to the Gold Nozzle, but with vocals that feel more relaxed and flowing. The unclear sound in the upper midrange is reduced, making it more comfortable to listen to.

Treble
- Gold Nozzle:
Fun, balanced, and engaging. This nozzle seems most suitable for all-around genres. The treble detail characteristic of planar drivers is clearly heard, as the power is fun and well-balanced with other frequencies. The treble is engaging with minimal sparkle and just the right extension. The metallic planar timbre is still present but minimal, especially in the upper treble in some tracks, and very bearable.
- Silver Nozzle:
The sparkle and detail feel even more refined. If the upper midrange were clean and not sibilant, this silver nozzle might be my favorite because the treble is engaging and the detail stands out even more.
- Red Nozzle:
Though it still presents micro-details well, there’s a noticeable change, especially in the sparkle, which is tamed to feel smoother and less energetic. However, when combined with all frequencies, I feel this nozzle is my favorite.

Clarity
A clear-sounding IEM, aside from the planar timbre that is still present, especially in the upper midrange and upper treble.

Soundstage
A bit above average. The airy soundstage and good dynamics enhance the sense of spaciousness.

Imaging
The 3D holographic imaging is excellent, with good head rotation. Pinpointing instruments is easy due to good instrument separation and dynamic instrument layering, which is one of the reasons I chose this planar IEM.

IMG-20240721-WA0029.jpg

==Ear Tips Selection==​

Because the IEM body is quite unique, finding a comfortable fit was a bit challenging. I recommend using ear tips that seal well and are snug in your ears, as the wide fit still allows them to sit comfortably. I use Eletech Baroque and Azla Sedna Crystal because they fit well in my ears. Additionally, if you want the vocals to stand out more with a good fit, try Divinus Velvet Wide Bore.

==Source Selection==​

- Mojo 2 - Analog, a bit warm
Very Recommended. The bass and vocal improvements make the bass feel more textured and the upper midrange more subdued, reducing sibilance in the vocals, though it is still noticeable.
- Fiio Q15 - Ultra Gain, Neutral and detail
Very Recommended, especially if you use the red nozzle, it’s fantastic. The bass feels more open and punchy, and the treble, though tamed, still feels present and refined. The vocals and midrange are musical and very comfortable. It has strong driving power too. Perfect. But if using the gold or silver nozzle, be more careful about sibilance.
- Hiby R4 - High Gain, Warm and vocal
Very Recommended. This "affordable" DAP with great power has no trouble driving the MP143. The vocals and sub-bass are clear highlights, especially the less offensive and more comfortable upper midrange.

IMG-20240824-WA0043.jpg

==Comparison==​

Since this IEM is priced similarly to the Letshuoer S08 and TinHifi P1 Max 2, and the TinHifi Dudu is already a clear loser, we’ll just compare it to the Letshuoer S08 and TinHifi P1 Max 2. Let’s go:
- Unboxing:
S08. The unboxing experience and accessories are clearly better with the S08.
- Fitting:
P1 Max 2. The slightly thicker bodyfeels more comfortable in the ears.
- Bass:
MP143. It suits my taste better. But if you prefer a darker sound, go with the S08.
- Mid:
P1 Max 2 and MP143. They feel more natural with balanced tone weight in all midrange sectors.
- Treble:
MP143. More sparkling with the option to change nozzles.
- Clarity:
S08. Clearer across all frequencies, while the P1 Max 2 and MP143 still have unclear sounds in the upper midrange on some tracks.
- Soundstage:
P1 Max 2. More open and airy than the MP143, and much more so than the S08.
- Imaging:
MP143. Dynamic imaging with good layering and positioning.

==Conclusion==​

  • Hidizs’ collaboration with WDC has once again produced an IEM that not only sounds great but also supports a good cause, particularly the conservation of whales and dolphins.
  • Inspired by "Salt," the humpback whale known for its "singing," the MP143 delivers natural and musical vocals with the option to enhance bass or treble through nozzle swapping.
  • Unfortunately, the unclear sound in the upper midrange and sibilance on some tracks may be a consideration.
  • Is this IEM worth buying? At $99, I think this is the planar IEM with the best technicalities and vocals that I’ve enjoyed so far.
That’s all.
Trust Your Own Ears.
Bye.

Hidizs MP143 Review: The Whale is Back
Pros: Legendary build quality (same as MP145)
Slightly improved comfort and fit
Extraordinary isolation
Tuning Nozzles
Great Bass and Sub-bass
Macro & micro details
Quite Wide Soundstage
No Driver Flex
Crazy low price
Cons: Shell is still big (not a real problem for my ears).
Needs power to fly (4.4mm recommended)
Tips rolling needed to achieve maximum sound quality
Lacks a little bit of air and trebles extension
MP145 is still better

IMG_20240731_090835.jpg
Disclaimer:​

The Hidizs MP143, or the “little” sister of the MP145, was the release I was waiting for with the most interest. Given the success and hype of the MP145, expectations were high. I can already tell you that, considering it is a lower model, it is still a really interesting IEM.
Like the previous one, this series is the result of a collaboration with the WDC for the protection of cetaceans and dolphins, and in fact, the design recalls, as always, a bit of the whale’s skin. I really appreciate Hidizs initiatives; there are not many brands that do collaborations for animal protection or the environment.

WDC Site: https://uk.whales.org/
I thank Hidizs for sending me a test unit.
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.

Tech Specs:​

  • 14.3mm large Planar Magnetic Driver
  • Impedance: 17 ohm
  • Sensitivity: 103db
  • Frequency response: 20Hz-40kHz
  • Hidizs Pneumatic Sound Tuning Filter
  • Target H-2019 Curve
  • Fully Symmetrical Magnetic Circuit
  • High-purity oxygen-free copper twisted wire – 0.78 mm, 2-Pin
  • Customized Pouch for MP143
  • 3.5mm or 4.4mm cable
  • Weight: 16gr
  • Early Bird Price: 99 USD (Super Early was 79 USD)

Packaging:​

The packaging of the Hidizs MP143 for the launch price is certainly well made, with thick cardboard and attention to detail. Opening the package, we immediately see the Hidizs MP143 in the Blue variant. The packaging seems to have been made of recycled cardboard and is an added value, especially given the collaboration with the WDC.

In the lower part, we find the tips that instead of the usual plastic bag, use a cardboard stick (brilliant), Inside the bag, there is the cable and the tuning nozzles. The pin that you see is an accessory that arrived to me separately, and I can’t tell you if it is included with all those who purchase the MP143.
Accessories included:
  • Pouch bag
  • 2 sets of tips
  • Balanced cable
  • Manual & Warranty Card

The only thing missing from the standard equipment is a hard case. I’m not a fan of soft bags because it’s easy to ruin the IEMs. The rest of the accessories are of excellent quality. The cable might be a little thin for some but at least it’s light.

Design/Build quality:​

Let’s talk about construction quality; the difference in terms of materials and finishing does not differ from the MP145. The Hidizs MP143 maintains an extremely high but simpler construction level. As you may have noticed, the construction does not include air vents on the faceplates. The design always recalls whale skin; in my coloring, the effect is even more marked. We can notice two ventilation holes, one placed on the inside and the other near the connector. In terms of size, I thought they were smaller; in fact, the difference is not huge, and the shape could still create some problems for smaller ears.

The faceplates, as you may have noticed from the photos, have a detail that is slightly “out of place.” The Hidizs writing, in my opinion, is backwards; when I wear them, the writing is upside down. I don’t understand if there is a valid reason for having put it backwards.

Initial sound impression:​

Given the expectations, I rushed to try them almost the same day they arrived. You can immediately tell that they come from the same brand; I didn’t have the same effect as the MP145 (I was really surprised with the first ones), which actually remains one of my favorite planar IEMs. The main difference is in the much less enveloping soundstage but in terms of tuning, they follow the same target.

The main difference, I think, is in the internal cavity and the fact that there are no real ventilation holes on the back. Despite this, the performance is still very high; it seems to me L-shaped or U-shaped at times, even if it should be more V-shaped. The bass is still decidedly present—a bass that is halfway between the planar timbre and the dynamic driver. Honestly, it’s really hard to hear the planar timbre. Mids, despite being recessed from the graph, still stand out significantly in the mix. Treble with a good extension but in terms of air, I think we could have hoped for something more. But being safe and smooth, they are tolerable on almost all occasions and also allow above-average listening volumes.

Comfort/Fit:​


As I anticipated in the design section, the Hidizs MP143 is not much smaller than its bigger sister. I would say it is a beautiful young whale. Ironically, the MP145 fit me better and for those who have seen my review on the subject, you will have seen the photos of how they fit me. However, even with these, it was only necessary to find the tips that could slightly fit into the ear canal, ensuring a stable grip and an excellent seal. Even given their weight, I did not notice any discomfort or painful pressure. To be honest, I had to use some teardrop-shaped Eartips (Divinus Velvet) to slightly lengthen the nozzle.

Hidizs MP143 360° Reel

Final sound impression:​

I start this part with an important premise. First, I reviewed the BQEYZ Cloud, which is decidedly bright compared to the Hidizs MP143.
As always, the good thing is that there are tuning nozzles, which do not distort the tuning but can vary it slightly. The eartips always remain the accessory that changes the sound more decisively.
My final opinion is given by the results obtained by the balanced nozzle and the Divinus Velvet.

I confirm the first impressions I had; even after several hours of burn-in, there were no differences. With the balanced nozzle, what is missing is a bit of fizz on the treble but it can be obtained with the silver nozzle. The performance is very respectable if we consider the price of 79 USD at launch.
As expected, the tuning differences are minor; the main sound variations are caused by a slightly smaller driver and fewer ventilation holes, resulting in slightly lower performance than the MP145. Being a less expensive IEM also makes sense.
They are IEMs with a considerable amount of bass; the sub-bass has a good emphasis; they are slightly warmer than the MP145; the mids are slightly recessed; but in any case, the driver brings them back clearly and cleanly separated from everything else. Are they IEMs that I would use every day? Absolutely yes, because they fully reflect what I would like to hear in my ears.

Tuning Nozzle:​

IMG_20240731_085609-scaled.jpg

Although the review was mostly done with the balanced nozzle, after a long time of use, I decided to try the other nozzles, and the difference is noticeable even if graphically there is not a huge variation. I will explain the variations to you in a moment.

Nozzle Colors:​


  • Red (Bass):
Honestly, I don’t think it will be the most used nozzle; unless you are extremely sensitive to high frequencies, this nozzle would take away detail and brightness from an IEM that already enhances the low frequencies. Using this nozzle will decrease the brightness, adding warmth. Even if the change is minimal, I found it to have no positive effects. In fact, if you remove the nozzle and look inside the nozzle, you will notice that there is a sponge that already filters the sound.
  • Rose Gold (balanced):
It’s a good compromise between the other nozzles; honestly, I don’t notice any particular shortcomings but it takes away some air on the high frequencies, dampening their brilliance a bit. It is useful if you are not super tolerant of high frequencies. In my opinion, performance is inferior to the MP145 on balanced; soundstage and air are not comparable, nor is the level of detail.
  • Silver (Treble):
In my situation, the magic occurred here. With the silver nozzle, the Hidizs MP143 reduces its gap with the MP145. The presence of air is re-established; I feel some more sparks that somehow also restore detail and clarity to the image that before seemed slightly veiled. Somehow, there is no longer all this difference from the MP145 except in terms of soundstage and definition. The MP143 is richer in bass than the MP145, which makes them suitable for the use of the silver nozzle. In my opinion, the combination of Divinus Velvet and silver nozzle is definitive.
Starting from a balanced result richer in bass and slightly less in treble extension, the use of the less filtered nozzle brings it to the level of the balanced MP145.
IMG_20240813_071016-scaled.jpg

Bass​

A decidedly marked presence of bass with a rumble on the subbass superior to the bigger sisters. They are not exactly the same enveloping and cavernous bass of the MP145; also, the sound pressure is channeled more into the ear and makes you feel a slight fatigue if you listen at high volumes (I have become slightly sensitive to the pressure of the bass). The MP145, with its particular system, discharged the pressure very well to the outside through the holes on the faceplates. Here, the presence is more substantial, but the quality is not superior.

Mids​

The mids are slightly recessed, but the planar driver maintains good separation, so voices are still audible and not too hidden. The tonality is not the most natural and silky, but the result is coherent. Perhaps there is just a hint of planar timbre. The musical instruments are clear and well separated from each other. The only flaw is that the bass is a bit overbearing and goes a bit into the mids, from what I hear.

Treble​

The treble lacks a bit of definition, especially with the red or rose gold nozzles. The presence of sparks and air is a bit limited given the type of driver; you could have aimed for something more. Fortunately, using the silver filter, you can re-establish a bit of balance and also raise the perception of micro and micro details. The difference between rose gold and silver nozzles is not very marked but with careful listening, in my opinion, you can notice benefits along the entire spectrum.

Soundstage and Imaging:​

Needless to say, the Hidizs MP145s do better but considering the launch price of 79 USD, for me, the performance is still astonishing. The soundstage is not huge but it develops well in width and also a bit in height. The image is not the most defined in terms of planar drivers, but it is still above average for the price range. The separation and layering, like any planar driver, are precise. We are not faced with the performance obtained by the MP145 but we are still at above-average levels.

Comparison:​

https://vortexreviews.squig.link/
Vs. Hidizs MP145
Hidizs Mp145
I have owned the first model Hidizs MP145 for quite some time. They remain my favorite planar IEMs, both for sound and build quality. What Hidizs MP143 does is done better by the MP145. It is undoubtedly a more refined IEM; perhaps the larger shell allows the planar driver to express itself better, and perhaps the particular ventilation makes them more open. The soundstage of the MP145 is huge, cavernous, and totally enveloping. The bass has a texture and depth that I have not yet found elsewhere.
As the photos show, the shell dimensions are very similar. You won’t see a big difference in terms of comfort but they definitely allow more positioning.

I thought they would be the turning point but somehow the fit is still not easy. The compact size of the Letshuoer S08 made me hope that they could be the definitive choice for those with similar ears but perhaps the nozzle angle does not allow much comfort in positioning. Everything is solved with the use of alternative eartips. However, the soundstage for a planar is much more compact, with good imaging and separation but in my opinion, Hidizs MP143 is slightly superior.

Kefine Klanar
Possibly the only viable option with notable comfort. Even though we are not as good as the MP145, we can still compete with the MP143 and S08. Though it has a signature heavy on bass, it still sounds fantastic and has a more refined soundstage than the S08. We are more towards the level of the MP143 with more rumble. Unfortunately, there are no tuning nozzles so even if the price is similar, the Hidizs are superior.

Conclusion:​

Hidizs Mp143
Hidizs MP143
I was waiting for it with considerable interest, curious to know if they could do better or something more compact for those with smaller ears. In reality, they have produced a model that raises the quality of entry-level planar IEM. I can’t tell you that its slightly smaller size or its performance are a turning point, but if you consider the price of 79 USD (the super early bird price) for an IEM with a planar driver, CNC machined shell, and tuning nozzle, well, it’s fantastic. Think of the Kefine Delci, which is positioned at 20 USD less but has a less elaborate shell, no tuning nozzle, and a dynamic driver (of quality). The requested amount of 79 USD is extremely low—it is comparable to the 109 USD requested for the MP145 launch. Regarding sound quality, there is not much to complain about at this price range. Even though the price is reasonable for all wallets, you might not like the tuning. The only criticism I can make is to pay more attention to the size of the shells, which, even in this case, will not be suitable for everyone.
The price has now gone up to $99 but I still consider it to be an extremely competitive price.
I am curious if we will ever see an even larger planar driver in a Hidizs IEM. I would be extremely curious to see either a compact model like an MP138 or an extremely large one like an MP150. Let’s see what the future holds; in the meantime, let’s save some whales thanks to the collaboration with WDC.

Hidizs MP143 “Salt” Review

Intro

Hello everyone, I have with me today the latest Kickstarter (early bird $79) planar earphone from the audio brand Hidizs named the Hidizs MP143 Salt. I was very excited to finally try out this set as Hidizs previous planar set, the Hidizs MP145, was one of my most enjoyed sets within its price point. Truly a legend status iem. Now, the MP143 isn’t really a “successor” in my mind as the price is listed at roughly around half the price of the MP145. The MP143 is simply another very well-tuned planar magnetic earphone, yet it costs quite a bit less. Definitely a good representation of this series of sets though, but not the heir apparent to the MP145. I do feel that the MP143 certainly has that same awesome DNA. I reviewed the MP145 last year (MP145 Review) and truly found it to be one of the best that you can get at its price. My question is if the MP143 will provide the same price to performance as the MP145, but yet just less expensive. We shall see.

Hidizs

Now, Hidizs has truly come a very long way in the earphones department. They’ve really provided the market with some fantastic iems. I’ve personally reviewed a number of them by now and each has its own flavor, its own style and each set has some distinguishing characteristics which separates them from the pack. Hidizs never does anything without purposeful intent and the motive of making money and providing good price to performance. Guess what, everyone wins. Of course, Hidizs began as a dap, dac/amp company which became a fantastic earphone maker. Again, each dac/amp, dongle dac, or dap has its own flavor and distinctions. I promise you people, not every brand does this.

All Positive

Honestly, I haven’t completed a review from this brand that didn’t end positively. Of the earphones I’ve really liked the Hidizs MS1 (MS1 Review), Hidizs MM2 (MM2 Review), Hidizs MS3 (MS3 Review), Hidizs MP145 (MP145 Review), and the Hidizs MS5 (MS5 Review). However, I’ve owned many more Hidizs sets in the past and enjoyed them all for different reasons. Of the Audio devices I’ve featured it’s a similar story. Those devices are the Hidizs SD2 (SD2 Review), the Hidizs S8 Pro Robin (S8 Review), and the Hidizs S9 Pro Plus (S9 Pro Plus Review). Again, I’ve also owned a number of Hidizs devices, and all are relatively great. Always a fresh look with clean lines and a fresh aesthetic that is also very well-tuned to whatever target that Hidizs was going for.

WDC

I think it should be noted about the collaboration effort between Hidizs and the WDC (Whale & Dolphin Conservation). For a couple years now Hidizs created a wonderful partnership where so much of every purchase goes to this cause through the WDC. In fact, everything about this product has some sort of a theme about protecting our oceans. From the plastic-free packaging to the design of these earphones etc. you’ll see the influence of whales, the ocean tides, waves, all the imagery. It’s all in honor of the sea and bringing awareness of our seas to the Hifi public. I realize it doesn’t seem like much, but every bit helps and it’s good to see at least some cause brought forth and honored from this crazy hobby that we love. Now, the name “Salt” was actually coined due to a certain humpback whale affectionately named… “Salt”. So, the name itself is a nod to this famously well-known whale. I think that’s pretty cool.

It’s in the DNA

The Hidizs MP143 comes at a good time in audio for the consumer but a tough time for any brand. I feel that no review should start without stating this fact. Even at the Kickstarter price of $79, the Hidizs MP143 is surrounded by fantastic iems which may steal some attention away from it. That said, one thing the MP143 has going for it is the fact that it carries the MP145 DNA, and it does so convincingly well. There are quite a few similarities between the two, and there’s some differences that I hope to spell out for you all. However, Hidizs has a lot going for it and all of the good vibes are in the corner of the MP143 Salt. Let’s jump into this review folks. Without further ado, the Hidizs MP143 everyone…

Packaging / Accessories

Unboxing

The MP143 came in a small black box with a picture of the MP143 adorned on its cover, some specs on the back as well. It’s a nice graphic of the iem. Open the box and you are met with the stunning MP143 earphones sitting in foam/cardboard cutouts. Just gorgeous. Pick up that level and underneath you’ll see the carrying pouch and the cable and tips. To be honest, this isn’t the most luxurious unboxing, but it does the trick. Also, what more do you want for $79 when Hidizs puts so much effort, R&D and time into the earphones themselves. Shoot, for $79 I’m surprised they even hand out a cable, pouch, and tips. Not bad.

Eartips

MP143 Eartips

Of the included eartips I found that neither really worked for my ears. For whatever reason. I actually opted for the Dunu S&S tips which worked for me in the MP145 as well. At any rate, the included tips are 2 sets of 3 pairs and 6 pairs altogether. The first set (S, M, L) is a dark gray silicone eartips with a narrow bore, fairly rigid flange and a slightly longer eartip too. Hidizs refers to these tips as their “Balanced” tips. The next set (S, M, L) is a white silicone eartip with a slightly wider bore (semi-wide) which Hidizs calls their “Vocal” tips. These tips are more shallow, flimsier as well and so it stands to reason they’d accentuate the vocal midrange areas a bit more. Both sets are decent enough but through my constant pursuit of finding the best audio possible for me I found that the Dunu S&S worked absolutely perfectly with this set. Besides the S&S tips I also used the Letshuoer blue wide-bore tips. Both sets worked nicely for different reasons. You may feel differently of course. Anyways, the packaging comes with some nice tips that’ll be good for certain situations for sure.


Carrying Pouch

MP143 Pouch

I actually like what Hidizs did here. I love a good carrying pouch. Probably more so than even a hard case. Of course, I’m probably in the minority there but I like a smaller pouch which can fit in the front pocket of my jeans. At any rate, the pouch given within the packaging is a very nice black colored and faux leather bag with a very nice open and close metal snap on it. You’ll notice Hidizs is imposed on the front as well. I don’t actually have a ton to say about it but it’s a nice pouch. You don’t always receive actual nice pouches. I’ll definitely use this one. Now, Hidizs also provided a pouch for the Hidizs MP145 as well and it too was a nice sized and nicely crafted pouch which I actually used. Anyways, I realize most of you would like an actual hard case but I’m sure Hidizs was trying to keep cost low in any way they could while still offering something nice as well.


Cable

MP143 Cable

This brings us to the cable. Hidizs provides a nice looking and very comfortable cable that actually works very well with this set. Part of the problem is that the actual build of these iems is not the usual. They are big folks, and the 2-ping connectors are high on the body putting them high on the ear. Or at least higher than most earphones. It does make finding other cables to use with this set a bit of an issue. However, the cable provided works fantastic! It is a 2-pin 0.78 very nicely twisted high purity oxygen free copper cable with a 3.5 single ended gold-plated jack. Usually, I’d want a big fat cable but with this set I found a thicker cable kind of moves them in my ear a hint more. Also, the thinner and lighter cable from Hidizs actually looks very nice. The cable can be purchased in either 3.5 single ended or 4.4 balanced. I did swap cables from time to time, but I found myself going back to the cable that is included in the packaging. I’m sure I’ll find one better over time but for right now I’m happy with what Hidizs provides.

Build Quality

What can I say folks? This set is built like a champ, through and through. Take a look at the build of the amazing MP145 and look back at the MP143 and what you’ll notice is that there really isn’t much of a difference as far as actual quality of build is concerned. I’m telling you folks right now, the MP143 is very likely the best built iem around $100. Made completely of aluminum alloy from the front to the back with intricately carved lines across the faceplates by way of CNC machining. You’ll notice the MP143 is pretty darn large, and I believe this is one of the main reasons the soundstage is so vast on this set and the MP145. Truly a beautiful build.

Tuning Nozzles

MP143 Nozzles

Like I stated, the Hidizs MP143 comes with three different sets of tuning nozzles to slightly alter how the MP143 is perceived. These filters are the type which screw “over” the nozzle. Meaning, the nozzles are actually caps with female threads that screw onto male threads. I prefer this style as they are easier to handle and not drop rather than tiny little nozzles that get lost fairly easily if not careful. So, the nozzles are labeled “Rose Gold” or “Balanced”, “Quiet Silver” or “High Frequency”, and “Charm Red” or “Bass”. Each nozzle does precisely what their names suggest.

Bass Nozzle (Charm Red)

The bass nozzle more-so lowers the lower treble through mid-treble region effectively causing the bass to sound a bit more pronounced. With this filter you don’t have as much air to the sound, heavier note weight by a small margin as well. At the same time the bass does have quite a bit more of a forward presence. Obviously, with the Charm Red nozzle you won’t catch as many details, and you do have a slightly warmer sound altogether. Still, I noticed a big uptick in actual bass presence.

High Frequency (High-Silver)

Once again, this nozzle does exactly as its name implies and ever-so-slightly boosts the upper regions. This is not some huge leap in treble activity, but you can hear some differences there. Basically, I wouldn’t expect mind bending changes, but the upper regions do come through a hair airier, and a very minor lift in overall levity to the sound. To be honest, the sound of this and the Rose Gold filter are very similar to my ears. Only very subtle changes.

Balanced Nozzle (Rose Gold)

Now we get to my favorite nozzle of the three, that is the balanced nozzle. I do feel the balanced nozzle has probably the best balance overall. This is the nozzle I’ve spent the most time with and the nozzle which I used for most of my critical listening. It has slightly more bass amplitude than the Quiet Silver nozzle but in all, they sound very similar and there’s very little real-world difference between the two except for minor changes.

MP143

Design

The Hidizs MP143 takes a beautiful page out of the Hidizs MP145’s book with a very similar build and shape. Again, the MP143 is made entirely out of gorgeous aluminum and comes in three distinct colorways. Those being, silver, blue and gun black. Obviously the set I have is the silver version. Just a gorgeous iem in every way you twist or turn it. The care and craftsmanship that went into dialing in the CNC machined parameters is just awesome. The design carries some lines in its faceplate supposedly to mimic that of waves in the sea. Just another nod to the theme of this set. Really a beautiful iem in my opinion with one of the most unique designs in all of audio.

Internals

Hidizs decided upon a 14.3 mm planar magnetic driver housed within the large aluminum shells. These drivers are said to have nano thin diaphragm’s along with a full symmetrical magnetic circuit. That circuit is composed of two fully symmetrical 7+7 N52H magnets which achieve around 1 tesla at the magnetic gap.

Fit

Now we come to the fit which will not be great for everyone. Just by the size alone there will be those who have a hard time with the fit. As for myself, once I achieve a seal then I have zero issues with the fit at all. Thankfully the MP143 is even lighter than the MP145 which also does help for comfort. Honestly, this is an area which may be different for everyone. Isolation is about average as well. Once a seal is made you shouldn’t have a ton of outside noise creeping in and when music starts playing those noises go away quickly.



MP143

Drivability

The Hidizs MP143 is rated with an impedance of 17 ohms and a sensitivity of 103dbs. I find the MP143 to be pretty sensitive and easy to listen to even less powerful sources. Now, just because it’s sensitive for a planar set doesn’t mean that giving the MP143 some juice won’t make your listening session better, because from my sessions I feel the MP143 really desires more power. Just like its older brother the MP145. Yet still, a lesser powered device can provide a good listening session, you just won’t be getting the utmost benefit out of the MP143. Really, it is like any planar set. Give it some power and it’ll shine. Same goes for the MP143. Also, you may want to watch what tonality type source you feed the MP143. I chose more dynamic sources, closer to neutral as well. I do feel the MP143 varies quite a bit with what source you choose. More so than most sets if I’m being honest.

Mobile Listening

MP143

One of my greatest joys is listening to my music on some hi-res mobile listening devices. What I mean when I say, “mobile listening” is really “dongle dacs”, “Bluetooth dac/amps” etc. I suppose daps are also “mobile” too. At any rate, something that can easily fit in your pocket and be… well… mobile. Anyways, I used a number of dongle dacs during my time with this set but I love the synergy with the EPZ TP50 & the Aful SnowyNight. Both devices carry roughly the same tonal characteristics. Both are closer to neutral, fairly dynamic and both have a ton of power on hand. Using 4.4 balanced and high gain on both really created a great sound. The tonality of the Simgot Dew4x also worked wonders as well. Again, high gain, 4.4 balanced. For my Bluetooth listening I used both the Qudelix 5k and the Ifi Go Blu. For both devices I used the balanced connection and for both I had almost no issues. Tonalities are a hair different between the two and I do like the IFi Go Blu a bit more as a pairing, but I’d be happy with both.

More juice

MP143

When listening with more powerful devices I went with the iBasso DX240 with Amp8 MK2 attached, the Shanling M6 Ultra, and the Fiio Q15. Each device replayed the MP143 very nicely. I do prefer the Fiio Q15 and its more neutral but also highly dynamic sound signature a hair more than the warmer Shanling M6 Ultra. I didn’t like the DX240 as much and I only say that because there was the slightest bit of planar timbre with that pairing. Not bad by any stretch but this is not uncommon with ES dac chips when paired with planars. Shoot, even with the slight planar timbre it’s still dynamic as can be and sounds very well-tuned.

What do you need?

I feel that if you are picking up the $79 Kickstarter Hidizs MP143 then you should at least have a nice dongle dac with some decent power under the hood. You want to stretch these drivers as much as you can because the entire spectrum tightens up, cleans up and generally sounds more authentic and visceral. So, I’d say at least a decent Dongle Dac. It doesn’t have to cost $10k. Just pick up a less expensive device like the EPZ TP20 Pro (which created a nice synergy) or the Moondrop Dawn 4.4 and you’ll be in business. You may want to try a more neutral sounding source, and it would be good if that source provided a dynamic sound with good energy. The MP143 will thank you for it.

Sound Impressions


The Hidizs MP143 takes a giant page out of the MP145’s book and does a variation of the 2019’ Harman target yet with some variables that haven’t gone unnoticed by my ears. The sound is warm/neutral to flat warm depending on your nozzle filter. As I said, I mainly used the Rose Gold nozzles during critical listening as it was my favorite sound profile. To my ears I hear a slight bassy U-shaped tonal character with splashes of energy in the upper regions. The MP143 has a wonderfully coherent mix of smoothness meets crisp. It has very fast transients, yet not to the point that instruments generally sound unauthentic. The sound is very good for a set which comes in at under $100 and can compete with sets that are above its price point in my eyes. That of course has the caveat that the person listening enjoys this type of sound. Of course. I hear fantastic detail retrieval and like I said, very nice transients with a hard lined attack and a snappy decay which helps the MP143 to really shine in faster and more complicated tracks. Very similar to its older sibling the MP145. The sound overall comes across with a slight recession in the lower midrange, a lean-lush note weight/body, and a slightly more mellow presentation. This isn’t some ultra energetic sounding set. To add to that, I don’t hear any real problems such as upper mid glare, shoutiness, or any real sibilance. Add to that the MP143 has wonderful resolution, and you have yourself a winner my friend.

Condensed Sound Between the 20’s

Note: before I begin going into the sound, I should preface that I did burn the MP143 in for roughly around 75 hours. Somewhere around four days give or take. I do feel this helped, same as I’ve felt on most planar sets I’ve listened to. It’s a nice set out of the box but giving the drivers some run-in, burn-in or listen-in does seem to be a help. Also, I used the Rose Gold nozzle for most of the critical listening on this set. I find it the most balanced. In this short section I simply give a condensed account of each area of the mix. Maybe a couple highlights of those areas anyways.

Bass

Beginning with the bass, it is deep, it rumbles (esp w/the bass nozzle) and the bass has a very snappy attack. Nothing soft, weak or brittle sounding. There is good density for a planar set. More so than the MP145 in that it was tuned with a pinch more emphasis in this region. Mainly that emphasis focuses a bit more in the sub-bass.

Mids

The midrange is actually very nice with a slightly richer sound in this region than the MP145. I didn’t say better! Anyways, it’s a warm/neutral midrange with the tiniest recession but also good presence in the mix. I don’t feel the mids are pushed too far back in the sound field. There is nice energy in this region especially in the upper treble which does offer some shimmer though for the most part it does have a slightly more mellow vibe. Very nice though.

Treble

The treble has fantastic separation, good body, nice dynamics and has great clarity. I hear some treble bite and some nice crispness at times. Especially when I feed this set some good power and a better source. The treble is nicely extended with a natural feel to it. Good resolution, even layering happening which says alot about these drivers.

Technicalities

Technically the MP143 is very good. Better than most under $100 sets. Detail retrieval is great, separation of instruments is well done, Imaging is pretty nice and there is some layering happening too. All in all, the MP143 is a very solid option at its price and even more so at the Kickstarter price of $79. Truly a contender if you enjoy the sound signature.

Again, it’s a form of Harman, but not really. It’s lusher than Harman, less glaring, without sibilance, beefier bass region too. Much more forward mid-bass, meatier and the pinna rise begins a hint earlier too along with better general treble extension.

MP143



Bass Region

The low-end is not for those who dislike a lifted bass. No flat bass lovers here. There is some spill over into the mids, there is some weight provided to the whole of the mix too. However, the thing which endears me the most about this bass is it’s quick hitting and dense nature. For a planar that is. There is a certain control exhibited out of planars that is hard to replicate with other drivers all the time. To that point, the MP143 attacks, decays and recovers extremely well yet the emphasis is such that the bass feels almost atmospheric, to a degree. It’s a very clean bass. To be honest, the actual quality of the low-end is very similar to the MP145 in many respects. The only difference is the actual quantity seems to be a hair more bulbous and heavier. Tuned a degree… more fun. Faster bass passages are really no trouble whatsoever. I don’t hear the dryness or papery style note inflection that I hear on some other planars. Granted, there are other great planar bass replays, but it was good to hear in this set. Basically, the MP143 hits n’ gits, has a deep and low bodied rumble and has a nice resonant response when called upon. There is some dip into the midrange as the bass shelf flattens out past 300 HZ which does provide some nice warmth to the sound. It’s nice folks.

Sub-bass

Being that the MP143 is a planar iem, it is usually a worry that the sub-bass wouldn’t have that resonant and textured rumble such as a good dynamic driver can usually provide. Well, I gotta say, just like the MP145, the MP143 is able to reach convincingly low in pitch coming across with a low drone and a haptic style rumble. Better said, it’s a sub-bass that you can feel. Now, the MP143 is sub-bass heavy, both on the graph and to the ear. Listening to “Heavy is the Ocean” by Bush (off their latest album) is a joy to hear because the rumble to begin this track is so dirty, deep, and guttural. It’s heavy folks! It’s mean! To say it another way, the MP143 is able to pull off what I envision the makers of this track wanted. The artist’s intent we call it. Of course, there are dynamic driver sets which do this routinely and with relative ease but hearing this region do so well from a planar and almost reach the DD level of bass depth, resonance, and density while also coming across superior in terms of speed and agility is so good to hear.

Mid-bass

The mid-bass is slightly less emphasized but also it doesn’t feel muddy at all from the rise in the sub-bass. I don’t feel definition is stolen from the sub-bass at all. In fact, note definition in the mid-bass is clean, it performs all transients in a rapid order and doesn’t come across pillowy, weak, or frail. Perhaps a hint softened in dynamics. That said, there’s still good texture to the mid-bass, which is evident with bass guitar, kick drums and good ole’ bass drops. Resolution is pretty good too although again, the MP143 does have a slightly softer attack. This is where I feel the MP145 out classes the newer MP143. Not by much however, although there are a couple of planars sets within its price point (Letshuoer S08, Artti T10) that do come across more punchy and more refined in this region. Full disclosure. Not taking anything away from the MP143. It hits hard, it can slam and the MP143 does so at a torrid pace if need be. In “Move Along” by The All-American Rejects, the kick drums begin the track right away and the MP143 does not let down. I hear a nicely tacky attack and hollow boom that is very satisfying to me. Also, Waxahatchee has a track called “The Wolves” which features a hearty bass guitar, and I can tell you that the MP143 honors that heavy handed riff with the fullness it needs. Hip hop bass drops are the same. You hear well controlled and textured bass that isn’t ever out of control or muddy.

Downsides to the Bass Region

The obvious 1st bass issue would be the quantity. Of course. I think we all know a handful or more of people who don’t enjoy any bass entering into their pristine mid-section. Also, I totally get it. Ya know, I love every single sound signature. I really do. I can find great joy in just about any of them. And so, I understand the perspective that too much bass almost adds too much personality to the midrange, too much coloration, too much softening the fine lines and glass lined note edges. I get it. There certainly are some sets that I say the same thing about. However, when you have a planar set like the MP143 which can quite literally make its bass dance in that quantity… I personally give it a pass. Meaning, yes, it’s dense, yes it’s thicker, yes it’s warmer, but folks… the agility and ductile style stop-and-go fast twitch muscle response is so cool. Beyond that there will always be those who simply don’t enjoy planar bass. Simple as that. They don’t like that it isn’t a DD and that it doesn’t have the same resonance and depth. Again, I get it. I do feel that the difference between the MP143 and a DD is ridiculously small. But I get it. Also, some will also say that the MP143 doesn’t have the punch, or the direct snap at attack that a set like… say… the Letshuoer S08 has. Also, I agree with them. Yet also, those are two different sets, each with their own strengths and weaknesses. However, at the end of the day you’d be hard pressed to find any set which comes across flat-out-better under $100.



Hidizs-MP143-Review-Pic-110.jpg



Midrange

The midrange on the Hidizs MP143 is all about its linear style warmth and richness that emboldens its midrange presence… simply by way of its note density and resolution. I hear a warm midrange which has a lean-lush style note weight. Similar to lean muscle mass as the notes are solid enough, they have mass to them and a textured and tactile edge. Now, there is a slight recession. However, that recession is not to the degree that I’d call them pushed back in the sound field. In fact, I’m half tempted to simply call this set a bass heavy U-shaped iem. It’s so close to that for me. I spend hours upon hours simply asking myself these ridiculous questions and I feel that the MP143 actually has a nicely positioned and well executed midrange that’s fast, textured, decently detailed, in spite of a slightly laid-back energy. Really a nice sounding midrange for vocalists. I hear a more organic sounding midrange without the usual skew of planar timbre (depending on the source, tips etc.). Hidizs really did a nice job of restricting the amount of metallic and edgy planar notes. Like I said earlier, certain ES dac chip source devices have accentuated that timbre to a very slight degree. Other than that, the mids are very natural sounding. No annoying level of sibilance, no shout, no crazy pinna glare. Not bad at all.

Lower-midrange

So, the lower midrange does take some of the warmth cast from the bass region and uses some of that warmth to plump up this area of the mix. What we have is a low-end intrusion which doesn’t seem like an intrusion at all but instead a gift. I happen to like the extra note weight. Granted, it isn’t so much that I’d call the lower midrange straight up “thick”. I’d call it what I have been calling it… “lean-lush”. It’s leaner in profile but also dense enough in actual perceived note mass. You have some very nice texture in this region which also helps to add some dimension to each note. This is also the area which is probably the most recessed. If you want to call it that. In my opinion male vocalists sound pretty nice. “Oceans of Emotions” by The Teskey Brothers has such a nice timbre and smooth inflection on the MP143. There is a richness which can be heard every single note out of the lead singer’s mouth. Really a nice sound which is complimented by some warmth. It gives males a certain authority to their voices. Now, strings in this area could use some edge to them but harmonics are great. Piano in this region has a full body and is very tuneful and clean. I don’t feel like I miss out on any details and separation is great. However, for the worst region on this set, it’s pretty darn nice to me.

Upper-Midrange

Now, females do have some shimmer to them. At least with the Rose Gold or Quiet Silver nozzles. Females do have that juicy style note delivery yet with nicely etched out note edges. Maybe not as moist as a good dynamic driver but very nice regardless. For instance, the MP143 is great for Adele or Lauren Daigle. Good for any female really. Lead singers such as Madison Beer in the track “Nothing Matters but You” really has a nicely toned-down luminance to her voice, almost euphonic to a degree. There’s emotion to her voice which is very well highlighted on the MP143. Not every set is tuned in this manner. It’s almost partially Harman but not as shouty, not as thin, and slightly plumper. I like how Hidizs tuned this set right to the brink of glare but stopped short and this track displays that well. You have about a 12 dB pinna rise which is also aided by some extra body to notes. Her voice is lovely, especially for a planar set. The natural timbre really does help to create an authentic sounding playback. Zara Larsson in “Soundtrack” has another slightly edgy voice which I would’ve thought would sound even edgier or more metallic on the MP143. This did not happen to my ears. She has a very melodic twinge to the sound of her voice with the MP143. I also enjoy how well separated her voice is from the surrounding Melody. The MP143 holds onto the more emotional

Instruments

Yet there’s also dimension to each note. Instruments seem to display this well. Such as violin which has that fullness that you want but also that silvery way about it which does have enough of a bite to give it that slightly edgy sound. Acoustic guitar has a home on this set, just so melodic. Every pluck, finger slide and resulting harmonics come across very nice. Just crisp enough, just smooth enough. Percussion has just enough snap on attack. Snares pang with some vibrance. The fundamental tone of a cymbal strike shows off a fullness as well, not paper, dry, or matte attenuated to my ears, and generally not splashy in their harmonics as you head towards the treble either. Perhaps there is a slight lack of vivacious energy. However, I do feel there’s just enough. Sax also comes across very nice. I could go on, but you get the deal when it comes to instrumentation. I’m sure some folks would desire more sparkly energy, or more sheen from the treble but the MP143 does such a nice job of bringing a rhythmic and soulful sound mixed very well with the technical side of things.

Downsides to the Midrange

Of course, if you enjoy a more analytically rendered midrange with less rich notes but rather even crisper and even better-defined notes with an even snappier and tighter transient response then the MP143 is not going to be for you. Without question there are sets within the range that have just that. I know plenty of hobbyists who adore an almost bright midrange with tons of energy akin to the Simgot EA500 for instance. On the other hand, some hobbyists would rather their money go to a set with an even warmer, and milkier midrange similar to a set like the Aful Explorer for example. You could say that the MP143 isn’t quite as detailed as some other planar sets or even iems featuring good balanced armature drivers like the Truthear Hexa. However, I feel the MP143 is very nicely detailed, and you really don’t miss much. Beyond those issues, the MP143 can exhibit some planar timbre depending on the source.

Real quick…

There are so many differences between all of us and how we perceive our music and what fits our individual tastes. I call these “downsides” but really, they are simply other people’s “possible” likes and dislikes, which may be different from the set I’m reviewing. I don’t hear anything at all that is downright bad, or off about the MP143. Nothing at all. Just different tastes. Many reviewers will proclaim that something is “bad” or an “issue” but make no mistake that those “issues” are only from that single person’s perspective. To be honest, I think the worst offense of the MP143’s midrange is that it’s a hair laid back in energy. Slightly softened attack which can lose a little bit of luster and crispness for instruments such as snares, cymbals etc. Yet I honestly don’t find that an issue with this price point. It’s simply not as dynamic in its presentation as some sets. I will say that after a little while I began to thoroughly enjoy this midrange. One reason that I haven’t really spoken about is the way the sound interacts with the soundstage on this set. There is this euphoric type of dimension which is very nice to hear for the price. I hear good layering of sounds and good separation and when you couple those attributes with good note density… It’s a good combination.


MP143

Treble Region

This brings us to the treble region which I feel is quite nice. Certainly not for treble heads, so bare that in mind. The treble has very good clarity and good resolution with a very fast transient attack through decay which will quickly recover most any treble notes. I hear a nice emphasis that strays from anything shouty. So not entirely boosted nor is it overtly brilliant, but just enough of a lift in the treble to slightly uplift the rest of the mix which contrasts against the bass region well enough to create some level of balance tonally. One may call it laid back, but I most certainly don’t think that’s the case. There’s some sparkle and shine up top. I also hear some crispness to the sound with solid energy that adds some moderate sharpness. Maybe jsut enough so as not to disrupt the beauty of the overall tuning. Definitely not enough brilliance and air to thin out the rest of the mix. Having said that, the treble does carry some air and openness along with fairly nice extension into the upper treble where harmonics don’t simply fade away but instead provide good info up top.

Well defined

Details shine forth rather easily too. I hear nicely defined notes which walk a fine line of smooth and crisp providing good body but also good bite to treble notes as well. Lately I’ve reviewed many sets with laid back treble as it seems to be a running theme of late. I could see some folks declaring the MP143 to be a hint laid back, but I feel it just has a less intense but still solid treble. Note body is rounded, full enough, never dry and never plastic, while coming across with decent note hardness. There’s definition there, not quite glass like but definitely not soft. Notes have more of a clean outline at the edges and even a decent bite at the crest of a note as well. Nothing grainy and without any fuzz or metallic tizz floating around in the sound field or around note surfaces. No sir, resolution is quite good for $79 considering the type of tuning that Hidizs went with. Not quite up to the MP145’s level but close.

Quick

The MP143’s treble is also very quick as those planar drivers are doing what planar drivers do. They move quickly with nimbleness & dexterity, almost like these drivers are scissor cutting the extra harmonics on some tracks hitting every note articulation, with very good cadence, pacing and coherence. Yet every rise and fall crescendo on the MP143 creates a nice dynamic contrast, not just flat, dull or boring. Again, it’s quick with great micro-dynamics as the MP143 navigates all the subtle volume shifts relatively easily. All those little pieces to my music that are rarely thought about have their own representation. The micro stuff. This all goes into the speed of this set. There’s less fat around the edges as the MP143 does a good job at maneuvering all the little modulations within my music very well. Take the track “Eye of the Untold Her “ by Lindsey Stirling. There are so many ballad style crescendos, volume shifts, and all the melodic abrasiveness that a violin can impart and the MP143 handles this track with nice timbre, good crispness, detailed too while sounding well separated against the rest of the melody and other instruments.

Some can do it better?

Now, having said that I should also state that there are certainly sets within the price point tuned even more so for bringing out the subtleties and nanoscale details. My words of praise over this $79 planar set’s treble region are all in light of the fact that the MP143 is a more bassy set, more fun, with a lusher approach. I suppose that is what makes it nice. However, beyond those things there is also good layering within the treble region and without creating any treble tizz or treble mudd, so to speak. No sounds really melt together if that makes sense. However, it is true that there are definitely sets that prioritize this region more, which would make them much more inclined to attract treble heads whereas the MP143 is definitely not a treble heads dream.

Downsides to the Treble Region

I’d first say that the MP143 is not the MP145. It just isn’t. There’s a reason the MP145 is more expensive. Granted it’s incrementally more talented in this region but it’s more talented, nonetheless. I feel this will be a point of contention for some who are expecting the magic of the MP145 to be improved upon even more on this set. Don’t get me wrong, I think the MP143 is fantastic for the price. So, treble heads or even moderate treble lovers will likely not find a home here. There are other sets for that. The MP143 is for folks who want a strong treble that holds up its end of the mix while also doing so with nice definition, note contour, bite and enough brilliance. I could definitely see some people wanting more of a lift though. Either that or less bass energy. One or the other. Still, I maintain that the MP143 does a solid job here and it has nothing to be ashamed of.

Technicalities

Soundstage

The stage on the MP143 is quite good. I hear very good width to this stage which is in my opinion definitely above average. This is one area that I feel benefits from having a larger acoustic cavity or housing. I also feel that the alloy being used helps quite a bit as well. There’s a wide feel, but probably average in height. Not super colossal, but big. Enough room for instruments to play around in, separation made a bit easier, layering, and even some depth to a smaller degree. Planars generally aren’t known for their ability to portray good depth of field all that well but the MP143 most certainly isn’t a flat plane of sound in front of me. The stage is somewhat immersive. Now, don’t expect the exact same big stage of the Hidizs MP145 as the MP143 is slightly less enormous. Still big though, still very nice for a set under $100.

Separation / Imaging

Separation of elements within an imaginary psycho-acoustically rendered stage is actually great. The only caveat is heavy bass tracks with persistent bass. Of course, those tracks nobody is listening for separation. They’re listening for the bass. Any other track and you’ll hear very nice instrument separation with very nice clarity. Imaging is pretty nice too. I don’t have any issue with placing left to right instruments and front to back is pretty nice too. Again, good layering of sounds which all helps to make for a good listening experience. I don’t feel that the MP143 separates elements within a stage as well as the MP145 and I feel like imaging lags behind its older brother as well.

Detail Retrieval

Detail retrieval is above average for a set tuned with such a bass presence. It is much better than it should be and a lot of that has to do with the actual speed of the drivers. However, there are plenty of sets tuned to illuminate the small stuff a bit better. That’s not to take anything away from this set though. I miss almost nothing in my music but there are moments where the sound field can become somewhat masked over from the low-end. Also, note weight is pretty lush and so that body does take up some room while leaving less space to clearly make out subtle details. However, I do think that detail retrieval is very well done on the MP143.

Hidizs MP145 / Hidizs MP143 / Letshuoer S08

Comparisons

Letshuoer S08 ($99)

Hidizs-MP143-Review-Pic-67.jpg

The Letshuoer S08 (S08 Review) is one of those sets that I simply fell in love with. Letshuoer is another brand like Hidizs who has perfected their planar sets and to be honest, it’s just a different flavor. The S08 features a 13mm planar magnetic driver that really covers the spectrum well. The S08 definitely is in consideration for one of the best sets money can buy under $100. So how does it stack up against the MP143?

Differences

First off, the S08 is much smaller than the MP143. However, it doesn’t fit better. I’ve heard plenty of folks complain about the actual fit of the S08. Granted, the MP143 may not be much better. So just something to think about. Both sets are built well but c’mon, let’s not kid ourselves, the MP143 is most certainly the better built set. On top of that it’s also the better-looking set from my subjective opinion. Both are nice but the MP143 is on another level in my eyes. Both sets have decent to good accessories but the S08 does come with a slightly better cable. Perhaps that is part of the price difference. Also, the S08 comes with a hard zipper case, so there’s that too. Granted, I like the pouch better but that’s neither here nor there. Also, the MP143 obviously has the ability to switch up the sound with its tuning nozzles while the S08 does not have that ability. Something to think about.

Sound Differences

So, both the S08 and the MP143 come across a bit warmer than neutral, both have a lusher note body, both have a nice balance of musical and technical, although the MP143 does have slightly more crispness to its sound whereas the S08 is all smooth with subtle bite and edge. The S08 is even more L-shaped than the MP143. I do hear a slight bit more warmth with the S08 whereas the MP143 w/the Rose Gold nozzle has just a tad more vivacious energy at times, mostly in the upper mids.

Bass

The MP143 definitely has a deeper and larger sub-bass emphasis with deeper lows however when it comes to the bass the S08 has the more punchy, rigid, and vibrant style bass with seemingly more weight to it. Not quite as deep, but heavier, make sense? The MP143 is a hair faster, yet not as hard edged on attack. I find the MP143 can take on more complicated tracks in this area as well. Having said all of that, if you choose the “Bass” nozzle on the MP143 then you will hair a weightier and deeper bass region with a heavier presence. For me personally, I like the Rose Gold/Balanced nozzle and so the emphasis is just fine.

Mids

The midrange on both sets sounds forward enough and not overly recessed but the S08 comes across a hint more forward and richer. Both sets are great for vocals though the musicality of the S08 is a bit better in this regard for me. However, technically the MP143 stands as the better set to my ears. Detail retrieval shines through easier with better separation of elements on the stage and slightly better imaging in my mind. I hear more vibrance and crispness in the MP143 midrange though both sets have very nice planar midranges.

Treble

The MP143 has just a hair more brilliance and openness with better separation in the highs. I find it to have a bit more crunch and bite, better for details, and slightly better extension into the upper treble. I honestly feel that both sets have a treble region that fits the tonal character of each set very well and I wouldn’t change either. Of course, you can very easily add in the Quiet Silver nozzle and gain even more treble bite and crunch on the MP143.

Technicalities

Like I’ve already stated, the MP143 is simply better in this regard. It’s not as thick in note weight and not as heavy handed in density and note mass than the S08. Also, the MP143 does have more openness and air to the sound creating better separation of instruments. Beyond that, transients are a bit quicker and tighter too along with a slightly wider soundstage. The S08 may be a hair deeper but I’d still say there is not some huge chasm of difference between the two.

Final thoughts on this comparison

Honestly, both sets are very nice for the price. Both have their own special sauce so-to-speak. I do find the S08 to have a more emotional draw to it, more musically inclined, more fun even. Despite that, the MP143 is the more technically savvy iem with seemingly better clarity, detail retrieval and technicalities in general. Honest folks, these two are #1 and #1A for me. Both are great and both are worthy of their price tags.

Hidizs MP145 ($149)

Hidizs-MP143-Review-Pic-66.jpg

This brings us to the lauded and loved legend of a set named the Hidizs MP145 (MP145 Review). The Hidizs MP145 is a true champion of its price point and it’s not really a fair fight between the two. I only add in this comparison for comparison’s sake. Maybe it’ll help the reader understand the MP143 better. So, the MP145 is a planar magnetic iem with a huge 14.5 mm planar driver and an even larger aluminum housing. Just a beast in all regards. By the way, in this comparison I’m only comparing the Rose Gold nozzles of both sets so do keep that in mind. This review would be 2000 words longer if I compared every nozzle. Nobody wants that. Plus, I think most people jive with the Rose Gold nozzles the most.

Differences

The MP145 is definitely a bit larger (though both are large iems) and the fit may be shakier due to that. I feel they are both crafted and built with the same care and precision. Both gorgeous, both are structurally engineered wonderfully. I couldn’t say which is better built. Perhaps I’d say the MP145 is the better-looking set due to the more intricate and larger back vent but honestly, both iems are striking to look at. I would say that the accessories are obviously better on the MP145, with a better cable, both have a carrying pouch (I like the newer MP143’s pouch better) and both have decent to good tips. Both sets have similar tuning nozzles, so no real change there. Obviously, the price difference is big and should be taken into consideration as the MP145 is about twice the price of the newer MP143.

Sound Differences

I won’t be long on this comparison because basically everything the MP143 does, the MP145 does a little better. It’s just the truth. The MP143 does have a warmer and thicker quality to the sound, richer note weight, slightly more planar timbre too. It’s not bad by any stretch but I didn’t hear any of that at all with the MP145.

Bass

I would say that the bass on the MP143 is heavier weighted, thicker, deeper too by a small degree. The MP145’s bass is able to handle quicker bass passages and comes across more resolving, harder edged, less softened.

Mids

The midrange of the MP143 is certainly more full, warm, rich, which gives males even more body and also helps females to come across juicer too. Honestly, the MP143 is mostly the more organic sounding set. That is until you hear some planar timbre creep up. Mostly this only occurs with certain sources for me as others I really did not hear it, and I was looking for it. However, I’d say the MP143 is a hair more organic to the ear… most of the time. The MP145 simply has a lightning-fast transient response, very well detailed, better resolve with each and every note, more holographic, airier and more open along with cleaner notes, not as soft in attack. Beyond that, the MP145 simply has more energy. Where some folks may complain about the MP143’s less intense or vibrant midrange, I don’t think you’d hear that about the MP145. Also, the MP145 has better note separation, and better layering abilities along with easier detail retrieval in this region.

Treble

The treble on the MP145 has a touch of extra brilliance over its younger sibling which extracts more details, better resolution as well. However, it does a couple more fun things as well like adds better bite to treble notes, some more treble punch and snap. I hear better note body on the MP143, however. Extension is pretty nice on both sets considering the tuning of both sets though the MP145 jsut has that last little bit of control to its notes that cannot go unnoticed. However, I don’t want my words to cast any shade on the very well done MP143.

Technicalities

I think we all know where this is going. Basically, the MP145 is better pretty much across the board. Better details, better focus of those details, cleaner and tighter transients, more glass lined note edges, less softened, better separation, more air to the sound. To add to that, the soundstage is phenomenal on the MP145 in all directions whereas the MP143 is almost there. It’s very good for its price but the older and more expensive MP145 is larger in that sense.

Final thoughts on this comparison

So, the one thing which the MP143 has going for it is that it does come across a bit more emotionally charged with a richer sound. You can see the trend as the MP143 is simply thicker across the board. This does a couple things positively and a couple things negatively depending on where you align your listening preferences. However, everything else is really a testament to just how special the Hidizs MP145 is. Truly it is the set within its price point which should be looked at first in my opinion. Especially if you are planar hunting. However, the MP143 is no slouch at all and a special buy at the price. It will go down as one of thee absolute best entry level planars on the market. I know this comparison wasn’t the fairest, but I do hope it helped at least a little bit. I suppose if you already have the MP145 then it may not make sense to pick up the MP143. Unless of course you are a collector, at which point… collect away!

Hidizs-MP143-Review-Pic-88.jpg

Is it worth the asking price?

Um, this is without question worth the asking price. I almost don’t even want to dignify this question with an answer. 1000% the MP143 is worth the measly $79 (not measly, sorry I get carried away) it takes to own it. Look at what you are getting. Now, I could see some folks not wanting this set for a couple reasons only. That is, they don’t like the tuning, too laid back in the midrange, not as crisp as they’d like, too much bass emphasis. And two, the fit is not good for them. Those are the two reasons. Okay three, if you simply cannot afford this set then that’s an obvious reason not to purchase it. However, besides those reasons, I find the MP143 to be a very well done “under $100” entrant into the market. Of course, there are so many iems under $100 that really do contend, not just planar sets. I could list them all out, but I simply don’t have the bandwidth to write them all down here right now. You know the major players. Anyways, it’s a tough market for any set. The MP143 has one huge advantage though and I think Hidizs will reap the benefits of that advantage very quickly. That is, it is the younger sibling of the legendary Hidizs MP145. The name alone will sell thousands of units. Still, beyond the name, beyond the “MP series” prestige, the MP143 actually has the goods to stand on its own two feet and disrupt the under $100 gatekeepers. Rather easily actually. Of course, you have to enjoy this sound signature. If you don’t then we aren’t even having this one-sided conversation.

The Why…

Because the Hidizs MP143 is clearly the best built iem under $100. I don’t think anyone can argue that. Maybe the Simgot EA500LM gives it a little fight but the MP143 is the king in that regard. The build is insane at this price. Hidizs hit an absolute gold mine with the build and design. Truly an accomplishment. Again, another reason is the actual look and aesthetic of this set. The carved lines, the odd shape, the beautiful aluminum, c’mon folks. Some will buy this set for the design alone. The MP143 also comes with some decent accessories, a nice cable, nice pouch etc. Also, the MP143 has working tuning nozzles which do actually change the sound. They are easy to screw on and off and help to tune things to three different variations of the MP143’s tuning.

Why, it’s the sound…

However, as always, it’s the sound that brings the money. In this case it’s the deep and extended lows with the tight note agility. It slams down low, hits hard, heavily emphasized too. Yet light on its feet and able to tackle any complicated bass track. The mids are well detailed, clean, forward enough but the best part is that they have a very nice and lean-lush note weight that helps this set to have a well-balanced musical and technically inclined sound. The mids are also nicely separated and reasonably airy with good layering and texture of notes. Also, the MP143 has nice treble in that there is some brilliance, some snap, some bite and some nice note body along with relatively good extension into the upper treble. All technicalities are well done as well. You have easy to distinguish details, its resolution is nice enough, you have good transients that come and go quickly as well as a solid soundstage with nice width and even some depth. It’s just a solid set folks, easily worth the asking price. In fact, $79 is a steal if you ask me.

Ratings (0-10)

Note: all ratings are based upon my subjective judgment. These ratings are garnered against either similarly priced sets or with similar driver implementations or styles with the unique parameters of my choosing. In the case of the Hidizs MP143 ratings below, that would be $55-$115 planar driver iems. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an iem what it is. A “5-6” is roughly average and please take into consideration the “lot” of iems these ratings are gathered against. $55-$115 US planar magnetic iems is not a huge scope of sets, and it’s also extremely competitive. It shouldn’t be too unreal to see a rating above a “9.0”, in my opinion. My ratings are never the same and each set of ratings tells a different story. Each time you read one of my ratings will be unique to that review. Basically, I create a Rating that makes sense to me.

Aesthetic

Build Quality: 9.9 Built extremely well.

Look: 9.9 Best design at the price?

Fit/Comfort: 7.7 Good for me, not for everyone though.

Accessories: 8.9 Very nice unboxing experience.

Overall: 9.1🔥🔥🔥

Sound Rating

Timbre: 9.4 Organic for an under $100 planar.

Bass: 9.4 Big, extended, impactful, speedy.

Midrange: 9.5 Musical, engaging, good note body, clean.

Treble: 8.9 Non-fatiguing, crisp, resolute.

Technicalities: 9.4 Very nice techncially.

Musicality: 9.1 Very musical.

Overall: 9.3🔥🔥🔥

Ratings Summary:

Did I ever tell any of you that ratings are a big joke? Why am I doing these? Now, I suppose that they may help some folks to some small degree but in reality, I don’t feel anyone should be making any purchase or even putting any stock in any man’s (or woman’s) ratings. They are opinions, folks. Before I argue against myself, I should add that I have the KZ X-HBB PR2 (PR2 Review), (it’s listed above $55 in some places), the KZ PR3 (PR3 Review), the Celest Pandamon (Pandamon Review), Celest Pandamon 2.0 (Pandamon 2.0 Review), the Kiwi Ears Melody, the Letshuoer S08 (S08 Review), Letshuoer S12, and the Moondrop Stellaris. I realize I’m missing a bunch of good ones, stop yelling at me! I have to actually be able to compare them or these ratings really mean nothing. So anyways, out of this lot of sets I draw my conclusions. Yes, there’s the Artti T10, the Tinhifi Dudu, Nicehck F1 Pro, etc. There’s a bunch more around this price. So, I was able to go through each rating attribute quickly going from earphone to earphone and rating per my subjective judgment. You may agree or disagree but hey… that’s what makes this hobby great.

Explain Yourself!!

I thought I’d have more areas where I could find some disagreement with myself per what I feel others may say, but not really. Definitely the “Bass” rating. Some sets are even tighter in this region yet not as full. The MP143 really has a bass that’s a “jack of all trades, master of none” style. I honestly feel the “9.4” is warranted. It isn’t the best, but it is definitely one of the best out of the group. Next would be the “Musicality” rating which means whatever the person doing thru rating wants it to mean because musicality is an overused word which has no real bearings as to how one establishes how “musical” something is. It’s what I feel musical is. So, feel free to call me names over that one, I get it. “Technicalities” may be another rating that brings on some ire from the peanut gallery. Listen folks, I put on a song, I listen with each set in a row, and I jot down my subjective opinion as to how well each set does between 0 and 10. Anyways, I honestly feel the MP143 is the 3rd best in general Technicalities against all of those sets. Only worse by a tiny margin too. So, you may disagree, and guess what… you aren’t wrong. Everyone is right in this game because everything is determined from the ear of the beholder. At any rate, I feel a “9.3” is about what I’d think the MP143 Salt should be rated at in overall sound. Which is tied with the Letshuoer S08 for the best rating out of those sets yet beating it the S08 by a few 100ths of a percent. All my opinion of course.

Conclusion

To conclude my full written review of the Hidizs MP143, I want to thank the good people of Hidizs as they provided the Hidizs MP143 in exchange for a review and feature at Mobileaudiophile.com. Not only that but they also stay up to snuff on everything, always. Never have I been offered payment, asked to skew my words or asked to pre-read any reviews. That would be the last time I engage with them if it were so, but they have never done anything against the Integrity of an honestly subjective review. This tells me a few things. For one, they believe wholeheartedly in their product and aren’t worried about reviewers’ opinions but instead will stand on the outcome. This says it all folks. Next, they will learn from opinions put out into the Audioverse and make their products better. I should also state that awareness for a good cause means their hearts are in the right place. I just feel it’s okay to give the brand some props every once in a while. Also, Hidizs… Nice work on the MP143.

Thank you!

I also should thank the people with whom all of these long reviews are written. That’s you, the reader.

A Casual's Review of the MP143 Salt
Pros: - Amazing soundstage and imaging
- Tuning nozzles are a great addition to switch things up
- Introductory price via Kickstarter is great value
- Help save whales when you buy this set!
Cons: - Large and heavy shell. May not fit all ears.
- Pouch may not offer enough protection for the IEMs
Disclaimer
Please note that I am not an audiophile, and this review does not delve into the technical aspects of the IEMs. My impressions are based on my personal preferences, and others may have different experiences with this product. I also have a very limited experience with audio products so please take this review with a grain of salt.

The Hidizs MP143 Salt was lent to me as part of a review tour in the Philippines.

Price: 99 USD (Kickstarter price), 159 USD (regular price)

Part 1: General Product Details

Package Inclusions:

  • IEM shells & cable
  • Carrying Pouch
  • 6 pairs of Eartips
  • 3 tuning nozzles
IMG_20240804_213157.jpgIMG_20240805_210450.jpg

The IEM Shells
  • The shells are CNC-ed from one piece of aluminum and has that bare-metal look. The sample I got was silver, but I know that there’s a bluish-black variant. The faceplate has the Hidizs logo printed with black ink (?) and below that are grooves in a staircase pattern (for lack of a better description)
  • Each earpiece weighs 7.8g without eartips. These are probably the heaviest IEMs that I’ve ever tried on!
  • These IEMs use the standard 0.78mm 2 pin connectors, so they are compatible with most aftermarket cables.
IMG_20240804_214657.jpgIMG_20240805_210828.jpgIMG_20240805_211406.jpg

The Carrying Case Pouch
  • The pouch is made of polyurethane leather, with the Hidizs logo printed in black. The pouch is easily opened and closed by a cinch.
  • It honestly feels cheaply made, and I don’t think this will last for a long time. I suggest using a hard case or one that has more padding to safely carry around your IEMs.

The Cable
  • Feels just like my Truthear Hola cables, nothing fancy on the outside.
  • My review unit had the 4.4mm jack so I had to use the Hidizs S9 Pro Plus Martha as source when using my computer instead of my ifi nano LE
IMG_20240805_211212.jpgIMG_20240805_211238.jpg

Extra: The Tuning Nozzles
  • This is a first for me to be able to use IEMs that have replaceable nozzles! Each nozzle changes the tuning slightly, and are of different colors to easily identify what each one is for.
  • The Red nozzles change the tuning of the IEMs and give it more BASS.
  • The Silver nozzles changes the tuning to have more TREBLE.
  • The Rose Gold nozzles are for a more balanced tuning. These are what I use and are my favorite!

Part 2: Subjective review
IMG_20240806_222523.jpgIMG_20240806_204037.jpg


General Usage Impressions

  • I was super hyped to try these out, but the first time I tried them on and the right IEM wasn’t going in well. The IEMs are heavy and have a large shape, which reminded me of the Elysian Pilgrims since I had the same problem with them as well.
  • Due to the above, I am unable to get a good seal, and have to constantly adjust the right IEM so it won’t fall off, which just made it frustrating to use.
  • I love the concept of tuning nozzles, it’s a great way of appealing to a crowd that have differing preferences, and makes the IEMs flexible enough to appeal to the majority. It was very easy to switch nozzles: just twist to remove and replace.
  • Since the MP143 I received only had the 4.4mm jack, I had to use a mobile DAC/AMP, I used the HIDIZS S9 Pro Plus Martha that was loaned to me by Mars.

Sound Impressions
  • I used the Rose Gold nozzles the most since I prefer the more balanced tuning than more bass and treble. The Red nozzles boosts the bass while reducing the the higher frequencies. The Silver nozzles do the opposite of this, reducing the bass while boosting the higher frequencies.
  • The first thing I noticed was the soundstage and details. These are AMAZING for listening to music and gaming! Definitely a set that I would want to use to give me a competitive edge when gaming
  • Listening to a busy track like Hatena by Penguin Research, the MP143 had great clarity and detail. I was able to hear specific instruments when I focused on them.

Final Thoughts

The MP143 sounds, looks, and feels amazing, the price to performance and value you get out of the box is a great deal! Plus you get to help protect whales, as Hidizs has partnered with the Whale and Dolphin Conservation! If you hadn’t noticed, they chose not to add plastics in their packaging. Thanks Hidizs!

But no matter how much I wanted to love this set so much, and how I was looking forward to get myself a pair, the fitment issues were the biggest detriment for me. If you do have larger ears, it’s a no-brainer, grab the Hidizs MP143 while it’s still on Kickstarter to save yourself 60 USD, and also save the whales!

DISCLAIMER

I would like to thank Hidizs for providing this review unit.

The Hidizs MP143 can be gotten here: https://www.hidizs.net/products/hidizs-mp143-large-planar-magnetic-hifi-in-ear-monitors (no affiliate links).

MP143 11.jpg



SPECIFICATIONS
  • Driver configuration: 14.3 mm planar driver
  • Frequency response: 20 Hz - 40 kHz
  • Impedance: 17 Ω
  • Sensitivity: 103 dB
  • Cable: 2-pin, 0.78 mm; oxygen-free copper cable; 3.5 mm or 4.4 mm termination
  • Tested at: $79 USD (kickstarter pricing)

ACCESSORIES

Other than the IEM, these are included:
- 3 pairs of wide-bore silicone eartips (S/M/L)
- 3 pairs of narrow-bore silicone eartips (S/M/L)
- 3 pairs of tuning nozzles
- Box for tuning nozzles
- Cable
- Carrying pouch

For a sub-$100 USD set, the packaging is quite decent, perhaps other than lacking a semi-rigid/hard case and foam tips.


MP143 15.jpg


2 variants of silicone tips are provided. The wide-bore ones boost treble and soundstage, whereas the narrow-bore ones improve bass quantity but with some compression of staging. The tips are impaled on an interesting kebab stick!


MP143 14.jpg


The stock cable is a 2-pin oxygen-free copper one. During ordering, one can opt for a 4.4 mm (balanced) or 3.5 mm (single-ended) termination, depending on your source needs. This cable is nothing special though, being quite thin and tangly, with some microphonics. There is a chin cinch for added grip.


MP143 16.jpg


Unfortunately, there is no hard or semi-rigid case provided, and we only have a leatherette clasp pouch to store the IEM. This should prevent scratches, but probably not a drop or impact.

Last but not least, we have the all-important tuning nozzles, which come in their own little box; the tuning nozzles will be discussed in further detail in the following sections.

The rest of this review was done with the stock cable and stock wide-bore silicone tips. No aftermarket accessories were used, so as not to add any confounders to the sound.


BUILD/COMFORT

MP143 7.jpg


Fashioned from CNC-machined aluminum alloy, the MP143 is robustly built. In tying in with the "sea" motif of the MP series, the MP143 incorporates 14 etched longitudinal lines along the faceplate, which evokes thoughts of waves or even a whale baleen.

Each earpiece weighs around 8g, which is lighter than the big brother MP145. Thankfully, it is also slightly smaller in size than the MP145 - please see the comparisons in the segments below. Having said that, the MP143 is still on the chunkier side for an IEM - understandably so to pack a 14.3 mm planar driver inside - but it definitely fits better than the MP145, which was the latter's Achilles' heel.

MP143 13.jpg


In spite of the larger size, for my average ear anatomy, the MP143 is quite ergonomic for extended usage, with no weird protrusions on the inner aspects to stab the ears.

Isolation is average, though I appreciate that it has no driver flex, unlike the MP145.

MP143 8.jpg



DRIVABILITY

I tested the MP143 with the following sources:
- Apple dongle
- Cayin RU7
- Chord Mojo 2
- Fiio KA11 dongle
- Fiio KA17 dongle
- Khadas Tone Board -> Schiit Asgard 3 amp
- ONIX Alpha XI1
- Questyle M15 DAC/AMP dongle
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Sony Walkman NW WM1A DAP (Walkman One WM1Z Plus v2 Mod)
- Smartphone

This IEM is moderately difficult to drive. While weaker devices can power it, the MP143 will scale with amplification in terms of bass tightness, dynamics and soundstage. So optimal sonics will likely only be obtained with at least a DAC/AMP dongle of moderate driving ability.


INTERNALS/TUNING NOZZLES

This IEM's engine is a 14.3 mm planar driver with nano-level diaphragms.

Like the original MP145, the MP143 comes with 3 tuning nozzles:
  • Red (bass) nozzles
  • Gold (balanced) nozzles
  • Silver (treble) nozzles
MP143 17.jpg


As per the graphs below, these are no gimmicks, and do change the frequency response:
Hidizs MP143.jpg

Graph of the Hidizs MP143 via IEC711 coupler. 8 kHz is a coupler artefact peak.

The red (bass) nozzle - as per its namesake - confers an L-shaped dark signature, with a sub-bass emphasis and a rolled-off treble. Note weight is thickest on this configuration, albeit with some loss of resolution.

The silver (treble) nozzle furnishes a mild V-shaped profile, with solid technical chops on display. It is the most extended in the treble but has the lowest bass quantity of the 3 nozzles, with the thinnest note weight. The gold (balanced) nozzle is a midpoint of the other 2 tones, showcasing a U-shaped frequency curve.


SOUND & TECHNICALITIES

The following impressions are done with the silver nozzle in use, which presents a mild V-shaped tuning.

MP143 10.jpg


With this setup, the MP143 has a sub-bass focus, with decent rumble to 20 Hz. Bass is speedy with minimal bleed in the mid-bass. Texturing is above average and it copes well with complex bass riffs. Overall, we hear a clean-sounding bass (the red nozzle is of course bassier but isn't as tight).

The lower midrange has a slight depression, but is quite transparent as there isn't a big bass encroachment. Upper mids hit ~ 7 dB ear gain, which pushes vocals forwards without overtly veering to shouty territory. This is in contrast to the usual steroid-infused upper mids in other CHIFI gear, and the red and gold nozzle will further tame down this area.

Treble has moderate extension, but even with the silver nozzle, the MP143 isn't a very airy set. This region is quite sibilant-resistant, so all-things-considered, the MP143 should be a safe offering for the treble-sensitive amongst us, more so on the red nozzle.

Timbre-wise, the MP143 unfortunately exhibits planar timbre, so notes sound a bit hollow especially for acoustic instrumentation. This is a common complaint for the majority of planar IEMs though.

In technicalities, with the silver nozzle installed and with amplification, the MP143 has quite an expansive soundstage in all 3 dimensions. Micro-details are present but it isn't the most analytical planar set. Imaging and instrument separation are average amongst the other planars.


COMPARISONS

The Hidizs MP143 will be compared against other budget planar sets and the original MP145. All-BAs, hybrids, and single DDs are omitted, as they have their own pros and cons due to the different transducer types.

Once again, comparisons will be done with the silver nozzle installed on the MP143.


Hidizs MP145


We kick off comparisons against its older brother, the crowd-favourite MP145 (the MP145 is the one on the right of the pictures below):
MP143_1.jpg

MP143_3.jpg

MP143_2.jpg


Dimensions-wise, the MP143 is smaller and lighter, so ergonomics are definitely better on the MP143. The MP143 also does not suffer from driver flex, unlike the MP145. Driving requirements are similar.

I've overlaid the respective individual nozzle graphs against the MP145 so that we can appreciate the tonal differences between the siblings:
Hidizs MP143 versus MP145 Silver Nozzle.jpg

Hidizs MP143 versus MP145 Gold Nozzle.jpg

Hidizs MP143 versus MP145 Red Nozzle.jpg



Across all nozzles, the MP143 generally has a bit more sub-bass and a less pronounced upper midrange. So the MP143 does sound warmer/bassier than its big brother, with a darker treble.

When it comes to timbre, the MP143 has a more obvious planar sheen. Note weight is thicker on the MP143 though.

The MP143 can hit about 80 - 90% of the stage of the MP145 (when amped well), but is behind in imaging and micro-detailing. In essence, the MP143 can get you close to the original big kahuna MP145 in soundstage, but the MP145 is still the superior IEM in other aspects other than ergonomics. The MP143 isn't exactly a chip off the old block, as tonally, it has a less pronounced upper midrange and greater sub-bass quantities.

Owners of the MP145 that can already fit it well should stick with it, as that IEM is still one of the gatekeeper planar IEMs of today. But the younger MP143 is a solid option for folks who can't fit the huge shells of the MP145, with just slight compromises.


Letshuoer S08

MP143 versus Letshuoer S08.jpg

Graphs of the Hidizs MP143 versus Letshuoer S08. 8 kHz is a coupler artefact peak.

The S08 is an L-shaped planar. The S08 is easier to drive, and has a thicker lower-end with less treble extension (it sounds darker than the MP143).

Timbre is more natural on the S08, and it has a thicker note weight. In technicalities, the S08 is weaker in soundstage and micro-detailing, but has better imaging.

The S08 has no tunability, so it is less versatile than the MP143.


Letshuoer S12 Pro

Letshuoer S12 Pro versus MP143.jpg

Graphs of the Hidizs MP143 versus Letshuoer S12 Pro. 8 kHz is a coupler artefact peak.

The S12 Pro is an aggressive V-shaped planar; it has a brighter treble, with more sibilance and harshness heard.

The S12 Pro has a more metallic timbre too. In technical aspects, the S12 Pro has a smaller soundstage, but has a hair better imaging. Micro-detailing is about on par.

The S12 Pro cannot be tuned, so flexibility in changing sound signatures still goes to the MP143.


CONCLUSIONS

MP143 9.jpg


The Hidizs MP143 is a solid entrant to the ultra-competitive planar fray. At the current kickstarter pricing of $79 USD, that is pretty competitive, considering you get 3 tuning options which are not gimmicky. In a way, it is kind of getting 3 distinct IEMs in 1.

The MP143 has good soundstage at the sub-$100 region, though amplification may be required to bring out the best in this IEM. It is relatively smooth in the treble, though retaining decent technical chops. Unfortunately, the MP143 displays planar timbre, which is a not uncommon bugbear amongst other planar IEMs.

The million dollar question will be if the MP143 can compete with its renowned older brother, the MP145. To put things in perspective, the MP145 is still the better IEM, but considering the MP145 is almost 2x the price, the MP143 does a fair job in just having a slightly smaller stage. The MP143 also has other compromises in technical parameters but improves on the fitting and ergonomics, which was the bane of MP145. Across all 3 tuning nozzles, the MP143 is also bassier and warmer than the MP145, so it isn't exactly a tonal doppelganger.

In a nutshell, the MP143 can hold its own in the sub-$100 planar ocean. Existing owners of the MP145 who face issues with its mammoth housings can consider the MP143 as a marginal downgrade, but for folks new to the planar game who are searching for a versatile set, the MP143 is definitely one to keep in the conversation.

Hidizs MP143 (in 4.4mm) Review!

Video review here

Good day! After 5 days of casual and critical listening, here’s my written review for the Hidizs MP143. The Whale calls!

========================================================================
Disclaimer:
  • I don’t read FR graphs. I only use my ears, as earphones should be used.
  • Hidizs sent this unit to me in an exchange for an honest, transparent review. Rest assured that this review will do its best to devoid from any bias/es as much as possible.
  • The following remarks and observations shall be made and owned only by me.
  • No monetary compensation is/was involved before, during, and after the period of creation of this review.
  • I have not reviewed or personally heard the Hidizs MP145 yet, which also means that I won’t be able to compare the sound of the MP143 to the MP145.
  • I will be reviewing this IEM in 4.4mm connection/termination. There may, or may not be differences in sound when paired with the 4.4mm compared to the usual 3.5mm termination.
  • Your mileage may (and always, will) vary.
========================================================================
Burn-in time: 4-8 hours per day, 5 days.

Source/s used:
  • - Non-HiFi smartphone (Infinix Note 12 G96), PC.
  • - Tanchjim Space DAC
  • - Hidizs S9 Pro DAC
  • - Aiwa XP-V710C CD Player (12 sec. EASS)
  • - Sony Xperia X Compact
  • - Local Files via Foobar, YouTube Music, Deezer, and Qobuz with UAPP.
IEM/Earbud/Setup configuration: Stock white preinstalled eartips, any form of EQ or MSEB off, 40-60% volume.

(Additional note here: I will be reviewing the Hidizs MP143 in its preinstalled “gold” nozzle filter first, then comparing it with the other nozzle filters after).

========================================================================
Sound signature:
  • The Hidizs MP143 in its stock configuration, is a balanced-warm sounding planar IEM. On certain sources, this IEM will sound closer to a mild-v-shaped sounding set.
Lows:
  • In its stock configuration, this is the highlight of the MP143. It is elevated, powerful, and subbass dominant for the most part. Despite it sporting a planar driver, the bass never sounded dry or lacking, which is a good thing because this also exhibited the planar driver’s speedy attack, decay, and detailed characteristics. This IEM is one of those planar IEMs that I can recommend to a basshead, or those ears who prefer a thick, elevated bass response. However, I also see the other perspective wherein some ears may find this lacking in terms of thickness and “sloppiness” to it (trust me, I know a handful of people who prefer their bass lingering and thick), which means that this may not fit the bill and they may want to look for a basshead IEM with a dynamic driver instead.
Mids:
  • Moving on to the mids, this region is very sensitive to sources and changes, in my humble opinion. In a nutshell, the mids are neutral in terms of position, it is thick as well, and may slightly recess depending on the power, pairing, and track played with it. Even changing the eartips affects the mids significantly. This can be a deal breaker to some, but I personally prefer this type of complexity because this allows most hobbyists to experiment their best configuration and pairing with this set, especially on the eartips. Lower mids are thick, smooth yet detailed. Upper mids are elevated, airy, and clear. There isn’t an abnormal sibilance and harshness in this area, but this set exhibits planar sheen well. Just like the aforementioned quirk earlier, this isn’t a deal breaker to those people who aren’t new to planar IEMs (even headphones), but something that needs to be considered for those people who are sensitive to upper frequencies, because planar sheen affects the upper frequencies in general (or in any IEMs with planar drivers) a lot.
Treble:
  • As for the treble, it is well-extended, has a decent amount of air and sparkle. There aren’t any forms of abnormal sibilance and harshness in this region as well. Detail retrieval is above average and will render microdetails with ease.
Soundstage, Imaging and Separation:
  • Having a very good technical performance isn’t a surprise when an IEM sports a planar driver, but there are certain IEMs that take it to the next level, in my opinion. The Hidizs MP143 is no exception in this quality. The soundstage, just like its whale motif, is big, tall, and immersive. Everything is just “out of my head”, with an excellent amount of height and depth. Separation and layering is clean and well-done, as expected for a planar IEM as it renders busy passages with ease. Imaging is precise and renders vocal and instrument positioning well.

========================================================================
Other Tuning Nozzle Filter Comparisons!

Silver Nozzle

  • The silver nozzle effectively shifts the sound toward the brighter end of the spectrum. The bass chunk has been significantly decreased, allowing the mids to shine better than the preloaded stock. The treble is also a little more forward than usual, but it's not a huge difference from the original filter. Overall technical aspects are also improved, particularly the soundstage. It is wider and more immersive than the stock filter.
Red Nozzle
  • The red nozzle warms up the overall sound when compared to the original fitted filter. Bass is thicker and more raised, yet it sounds slower than usual in my ears. Also, mids are smoother and thicker than usual. The treble is also smoother, but it lacks the extension and air that I prefer. Technical aspects were also compromised, particularly on the soundstage. However, this nozzle filter has the least amount of planar sheen and timbre when compared to the rest of the filters.

========================================================================
Other IEM Comparisons! (With stock preinstalled nozzle filter)

Letshuoer S08

  • In my opinion, the Letshuoer S08 and MP143 goes toe-to-toe with each other in terms of their overall sound quality. They both have audible differences when compared side by side. The Letshuoer S08 is a neutral-warm sounding set to my ears with a slightly forward and well-bodied mids when compared to the MP143 as the mids on the MP143 is mildly laid-back, particularly its lower mids. Bass is definitely more elevated and chunky on the MP143, but the Letshuoer S08 sounds more “dynamic” which made the MP143 sounded a bit dry when compared side by side, if that makes sense, due to its slightly different driver technology when compared to the MP143. Soundstage is also wider and more immersive on the MP143, while the separation, layering, and imaging are nearly identical on both sets. The Letshuoer S08 also has significantly less planar sheen/timbre when compared to the MP143 but is slightly less capable of rendering microdetails easily.

7Hz Timeless, Letshuoer S12
  • Both of these sets are nearly identical to the MP143 in my humble opinion in terms of timbre, but the MP143 outshines both IEMs in terms of sound refinement, particularly in the treble department. The treble is less “thin and/or brittle” on the MP143, and renders microdetails easier when compared to the Timeless and S12, but not by a long shot. Soundstage is noticeably wider and more immersive on the MP143 as well, while the S12 and Timeless gives that “usual wide-flat soundstage” when compared side by side. Planar sheen on all aforementioned sets in this section are more or less the same in terms of amount.

Tangzu Zetian Wu
  • The Tangzu Zetian Wu is a warmer, thicker, sounding set when compared to the MP143. This also means that it is a bit slower in attack and decay when compared to the MP143. Mids are a bit thicker on Zetian Wu as well. Treble is safer on the Zetian Wu, but both exhibit a noticeable amount of planar sheen. Technical performance is better on the MP143, especially on its soundstage. Everything is just immersive and grandeur on MP143 when compared.
========================================================================
Pros:
  • A warm, versatile-sounding planar IEM (subjective).
  • Warm, smooth, thick sound character.
  • Subbass-dominant, thick yet agile bass response!
  • Lush, thick mids!
  • Non-fatiguing upper frequencies!
  • Wide, immersive, holographic soundstage!
  • Clean, precise technical performance! (It’s a planar)
  • Very good fit, comfort, and isolation.
  • Straightforward tuning nozzle filters!
  • Very good quality of accessories!
  • Well-thought overall motif!

Cons:
  • Planar sheen is apparent.
  • Driver shell will be big in size when used with smaller ears.
  • Very sensitive to synergy/source pairings (May or may not be a deal-breaker to some)
  • Unforgiving on poorly recorded/mastered tracks (This is not really a negative on my end, but probably for some people)
  • A hard case would’ve been a treat for everybody. (subjective)
========================================================================
Verdict:
Hidizs takes its audience’s opinions very seriously, as evidenced by the MP143. It is unusual for an IEM with a planar driver to have a slightly smaller IEM shell, a wide, immersive soundstage, and non-lacking bass. Aside from the general sound quality and its humongous soundstage for an IEM, what I particularly like about this IEM is how they adhere to their theme in terms of presentation and visual quality. A whale motif on an IEM is an unusual touch that breaks up the monotony of most IEM designs on the market. Not to add its "nature-friendly", plastic-free packaging, which demonstrates their commitment to saving and preserving whales in wildlife. Overall, the Hidizs MP143 is an excellent option if you are looking for a versatile, all-rounder IEM with a planar driver with very good technicalities, assuming that you have a pair of ears that are on the larger side and have a source that can power this IEM sufficiently. Well done, Hidizs!

========================================================================
Pairing recommendations:
  • Source: The Hidizs MP143, as all planar drivers are, need a bit more power than usual. A source with at least 200mw of power will do for the most part. A 4.4mm/2.5mm balanced connection is also a bonus addition to ensure sufficient power driving this IEM.
  • Eartips: The eartips are more than enough for the most part, but you may still use your preferred eartips.
  • Cable: In my opinion the cable is well done and fits the intended whale motif, but you may still use your preferred 2-pin cable.

Thank you for reading!

New Head-Fier
BIG MISSION BIG SOUND
Pros: - well balance tonality
- technical ala planar
- good texture for planar
Cons: - a bit awkward fit
an iem with Big Mission, this time Hidizs again in collaboration with WDC (Whale & Dolphin Conservation) helps to promote good quality iem for good cause

every purchase of mp143 will support this conservation organization (you’ll get this cute whale pin)

and i just love how we can actually feel that start from the packaging that every part of it is biodegradable, no plastic is used, and i truly appreciate their effort for this

you’ll find unusual materials being used here such as resin for the nozzle case, layered paper for the box instead of foam, also this hardened stick like carton(?) for the eartips (photos below)

now for the iem itself is a bit larger than usual but still looks and feels good in my ears and yes they are also inspired by the whale shape

i do have a bit of problem in fitting because the nozzle is relatively small compared to the housing, using the default stock tips i couldn’t get proper depth and seal in my ears

if you find similar problem i suggest using eartips with long stem such as spinfit or personally i use ddhifi st35

you’ll get 3 different tonality in different nozzles and it shows in the FR

but the red one for me pushed the midrange too low making in sounds darker and too basy

the silver is okay, leaning more of V response

while the gold for me is the most balance and ideal, so this will be mostly tested and tried using gold filter

for me it sounds exactly as the Fr shows mild U shaped with elevated bass that goes deep, a step back in midrange while retaining a bit of low treble bite to make things exciting and the treble itself is a touch forward but still smooth having a good sparkle while not being so extended

put it simply it is well tuned nothing feels off, lacking, or too much in extreme way

but that is the special part, i can hear it all day without any complain a simple mild U fun tonal with planar fast transient with somehow big stage sensation

to put things into perspective
here’s some quick comparison
7hz timeless : is the classic first proper planar iem for me but for long listening i feel fatigue due to big midbass plus forward upper mid
s12 : is the tightest and brightest i love how it gives a precise bite and attack but again for long listening it’s too sharp for me
s08 : is a special one, total opposite of s12 have one of the thickest sounding planar while keeping the planar speed i love hearing some vocals through them but can be a bit boring after some time lacking attack and bite
mp145 : only tried them a few minutes but before i could assess the sound i’m sorry i’m mostly bothered by how big it is and i couldn’t wear them properly

so that’s it, mp143 might be not the most wow planar but after hearing it for days…. i can say it’s the one that i will use if i only need 1 planar
