These past years have been successful ones for Hidizs, marked by highly regarded releases such as the MK12 Turris, MK10 ArcSonics, AP80 Pro Max, MP143 Salt, and of course, the legendary MP145 which is widely touted as the best value-for-performance option in the planar IEM realm. To kick off 2026, Hidizs has announced the return of the MP145 with a new Pro version, featuring further refinements while strengthening their partnership with the Whale and Dolphin Conservation (WDC) group. It’s a big shoe to fill, and expectations are high for the MP145 Pro. Can it be another hit? That’s what we’re here to find out.
Firstly, here’s some information on the WDC group. Please feel free to support their cause.

Packaging & Accessories
The packaging here is a major step up from the original MP145 and it is the most complete packaging with high quality accessories amongst all the products of Hidizs. Boxed in a solid cube shape box that is slightly large with a WDC 2025 autumn newspaper and a whale pin badge. Inside we are greeted with the MP145 Pro IEM head with 4 types of eartips including the Hidizs Sea Anemone eartips, a high quality leather hardcase in ocean blue, a high quality modular cable and of course, their highly regarded Pneumatic tuning nozzles. I really love the upgraded unboxing experience and the high quality accessories. Here is the full list of the included accessories.
Design
The design here is surely similar to the original version but with a more techy, futuristic design and they share more similarities with the blue whale’s tail. It has the same large size shell and they are slightly thicker than the original ones but possess a good ergonomic fit with a rather lightweight shell at 9.5g per piece. Small ears users might have fit issues but they fit just fine for my slightly large ear conchas. The shell is made from CNC aluminum alloy with an optimized cavity, available in Blue, Black and Gold alongside a limited 299 piece for the titanium version. The shell now has a baked-painted type of finishing and they do not scratch as easily like the original ones do.
Driving the MP145 Pro is a new, upgraded 14.5mm planar driver that is named the Fast 2. It boasts an ultra precise, nano level planar diaphragm that is custom developed by Hidizs and it provides a rich and detailed delivery of sound that they have been known for. The driver utilizes 7+7 Array N54H magnets, now with increased magnetic efficiency, delivering a 40% increase in magnetic flux that gives a 1 Tesla magnetic flux for a flawless sound delivery.
Included with the MP145 Pro is the famed Hidizs Pneumatic tuning nozzles with 3 colour coded screw in type of nozzle that gives a different tuning presentation that really works well. The diameter of the nozzles are now slightly smaller at 6mm at the tip compared to the original with a 6.5mm diameter and they are slightly longer as well. Here are the nozzles description by Hidizs;
- High Frequency (Silver): Ideal for instrumental, orchestral, anime soundtracks, and complex arrangements, enhancing separation and clarity.
- Balanced (Rose Gold): Perfect for Mandopop, J-Pop, and emotional vocals, offering a balanced sound that brings vocals forward with natural warmth.
- Low Frequency (Red): Designed for bass-heavy genres like EDM, rock, and pop, this filter deepens the bass and adds more immersion to your music.
This review will be made using the balanced/gold nozzles which is the default nozzle. There are 2 wide rectangular vents on the faceplate beneath the fins named Bionic Breathing and they are huge indeed to provide sufficient breathing room for the drivers, contributing to their large, airy soundstage. There is another pinhole vent near the nozzle for pressure relief and gladly, no driver flex are present as they are a very well vented IEM.
The MP145 Pro has the standard flush 0.78mm 2 pin connection that is slightly tight.
Cable included a new, modular oxygen free copper that is plated with silver in greyish black colour for the black colour version (clear silver for the rest) and it comes with a 3.5mm and 4.4mm balanced head. It is a 4 core braided cable with metal parts used and they are soft and pliable while also feels robust, suited for everyday use. This cable might be the best cable that is included for Hidizs products and they matches the looks and sound of the MP145 Pro

Tone and Presentation
The sound presentation is now a neutral bright, Harman 2019 sound tuning but in a more refined way with their neutral balanced tuning that has a large soundscape with excellent details retrieval and a smoother high range that has minimal planar timbre. Compared to the original MP145, the Pro version has a more organic approach that isn’t as energetic but it has a more speaker-like sound that resolves better than the original version. Timbre is organic, brassy and breathy with a fatigue free listening while still possessing a high degree of excitement in the lows and highs. The planar timbre here does sound more natural that is more similar to a dynamic driver’s timbre without any major issues like a metallic tinge present.
Soundstage
The soundstage here is impressively expansive with a superb width and height that punches above their price range, probably one of the widest in the IEM realm. The MP145 Pro possesses an accurate 3D holographic spatial soundstage which makes it perfect for gaming and movies as the sound placements are accurate and directions are distinguished easily. Immersion here is superb and they are capable of giving a diffused sound that disperses sound around, giving an out of head type of sound that is accurate and airy alongside a huge headroom feel. The so-called Bionic Breathing vents really work wonders and I do feel the soundstage is a little wider than the originals.
Separation and Timbre
Separation here is impressive and they have good separation of sound that gives a wide stereo sound with no major crosstalk issues and they do sound better with a balanced setup. The sound cohesion is great as being driven by a single driver where all the sound frequencies are displayed in a harmonious way without any gaps present. Dynamic range is good with extended lows and highs enabling a wide stereo effect that increases their airiness. The MP145 pro does have some minor colouration present that gives a more vivid sound but it doesn’t hamper the overall naturalness of the sound.
Drivability
Rated at 30 ohms with a 104db sensitivity, they are easily driven by any source as they don’t need much power to perform and have an adequate amount of loudness. Their slightly low sensitivity does not tend to pick up noise and they have a black background noise suited for any usage scenarios. Scalability here is good and they do match easily but best especially with a neutral source but that increases their overall technicalities. The MP145 Pro is slightly revealing and they are able to show some flaws in the recording and a good mastered track or higher bitrates files will actually give a cleaner sound. These aren’t really a pair of IEM tuned for monitoring and critical listening but they do have the capabilities to be one. The MP145 Pro can be considered as an all rounder IEM that suits various listening scenarios and the tuning nozzles inclusion does give users more flexibility in matching their taste.
The Bass (Low)
The bass has a neutral flat approach that has authority when called upon and the bass here is energetic with a good amount of meat with a tightness in their slam. The mid-bass lift here is actually natural as they are present without any overpowering issues and they are indeed a versatile fun bass that plays well across all genres. The mid-bass amount is actually lower than the original MP145 but by a small margin. Details and clarity here is great with a well textured bass that is both clean and clear while having a superb nimbleness that mimics a dynamic driver bass. Resolution and transparency here is great with a vivid and accurate bass that has a good pace enabling them to handle busy tracks without being muddy or bloaty with no bleed is present here. Extension of the bass is decent with a slow roll off that gives a lingering bass that has a good amount of air. Sub-bass is also slightly lifted that blends well into the overall bass and they possess a strong, clean rumble that dives deep. Although the bass here has the authority, I wouldn’t recommend this set for bassheads as the amount here isn’t enough to satisfy users who yearn for a bass dominance amount but great for casual listeners who want a slight boost of bass to prevent the overall sound from being too polite or boring.
The Mids
Midrange here has a mostly neutral sound that manages to stay present with a slight forwardness in their presentation transitioning well from the lower mids and with a mild peak towards the upper mids. There is some warmth present in the mids with a good amount of space that has accurate spatial accuracy. Clarity here is superb and they are able to give a clean and a crystal clear sound that is resolvingly vivid with a small dash of colouration that makes the overall mids more fun. Details here perform well in macro and micro details are well presented. The body here has good thickness with a full-bodied, rich sound that possesses an organic timbre with no major metallic planar sound, instead the mids with their mild warmth produces a good musicalities that excels in lushness and is highly enjoyable. There is a mild peak in the upper midrange that gives the MP145 Pro a mild brightness that possesses some brilliance for a livelier sound signature. Vocals here are balanced with a good amount of brilliance and they have a good depth. Instruments like strings, woodwinds and any high staccato sound good but also excelling percussions and bass instruments.
The Highs
The high here is neutral with a rather balanced type of presentation that has a small peak at the 8 to 10khz region, producing a present high range that has a good amount of energy without being too piercy. There is a steep roll off at the highs here upon looking at the frequency graphs, but for me the high range has good presence here and although isn’t as energetic as the originals, they are indeed smoother and more natural. The high range here does have their presence with some bite and liveliness that isn’t polite or too tame. The sparkle here is lively and they do possess a mild crisp decay making the high range more enjoyable. Timbre here is good and they do have the accuracy but on certain bright sources, they tend to have a mild metallic sheen but in a small margin, not as bad as most planars out in the market. Air here is good but rather average as they do have a slightly fast roll off at the end. The high range energy here is slightly high but they are smooth without any sibilance, shout or hiss present and they aren’t as fatiguing as the original MP145 albeit less exciting. Treble here has a small intensity that gives the overall sound a good push in their clarity and they aren’t really a treble that is suited for those who want a relaxed, laid-back sound type.
Comparisons
VS Hidizs MP145 (159USD)
The legendary MP145 which where the Pro version is based from with a similar sized planar at 14.5mm in diameter. They are touted as being the best price versus performance index planar IEM in the market till date and the sound is indeed more energetic especially in the high region when compared to the Pro version. Timbre on the Pro version does sound more natural but the MP145 has the edge of being bolder and exciting. Packaging and accessories wise on the Pro is way better with better modular cables, better eartips selection and a higher quality leather case.
High range on the MP145 produces a more livelier sparkle, with a crisper sparkle. Timbre on the Pro version is slightly more natural and they are smoother. The Pro version is more resolving as some highs are more vivid but the overall details and clarity are identical. Treble on the MP145 has an extra intensity to them that gives a clearer perceived overall sound.
Midrange on the Pro version is slightly thicker and lusher and has better musicalities. Details and clarity are similar but the MP145 sounded slightly cleaner and slightly clearer. There is a bigger lower midrange peak on the Pro version that gives them a deeper sound signature. The Pro version mids have some forwardness to them and they are more slightly more intimate while the MP145 has better spatial accuracy with a more spacious mids.
Bass quantity here has a bigger presence with more authority on the MP145 with their bigger mid-bass lift and a tighter bass slam but the sub-bass on the Pro version sounds deeper. Details are similar but the MP145 bass does sound cleaner with better texture while the overall bass of the Pro version has a more organic approach.
The soundstage on both has very similar width and height but the Pro version does sound a little airier and spacious in their headroom.
Verdict: Both are actually a side-grade to each other where the Pro version is more mature, organic sounding and the MP145 original has the better energy and excitement.
Vs Letshuoer S15 (299USD)
The S15 from Letshuoer is a single planar driver IEM and they are possibly the best in terms of performance when it comes to planar drivers. It is quite pricey but the price has actually come down to circa 200USD. Built here is a matte 3D printed resin in collaboration with HeyGears and they have a complete, premium packaging which is similar to the MP145 Pro. Both sound signatures are actually quite similar with a neutral balanced presentation but the bass on the S15 is slightly boosted. There is a slight driver flex present on the S15 but their fit is better due to the smaller size shell.
The high range on the MP145 Pro has a smoother approach but still has their presence with good sparkle and crispness. Details on the S15 here are better and they are livelier but both have similar clarity. Timbre is better on the MP145 Pro but by a small margin. Both high ranges extend well and both possess a good amount of air.
Midrange on the S15 Pro has a clearer midrange with better details and clarity while the MP145 Pro has a warmer mids and thicker body. The mids of the S15 are more accurate and resolving while the MP145 Pro has better musicalities. The S15 has better brilliance in the upper midrange that sounds livelier with female vocals.
Bass on the S15 has slightly more mid-bass lift with a tighter slam but the MP145 Pro is more accurate. The sub-bass amount on both are similar with a big, clean rumble but the S15 sub-bass dives deeper. Texture is slightly better on the S15 and they do possess better energy.
The soundstage on the MP145 Pro is slightly wider and taller while possessing more air due to the bigger vents at the back.
Verdict: In terms of technicalities, the S15 is slightly ahead but the MP145 Pro does sound bigger in soundstage and they have the edge in value.
Synergy
Synergy wise the MP145 Pro is an easy match for most sources from warm to balanced to bright sources from the likes of AKM, Circus Logic and Burr Brown but preferentially I would not recommend some Sabre based chipset with the infamous hump as it may incur some metallic planar timbre.
Good matching: IFI Diablo, 7HZ Artemis39, EPZ TP35, Qudelix T71, Hiby FC6, Cayin RU7, Questyle M15, Hidizs S8 Pro.
Not so good matching: FiiO Q7, FiiO KA5, EPZ TP30.

Final words
Whale, whale, whale, does the Hidizs MP145 Pro make a splash? For me, the answer is yes. The tuning here is spot on, delivering a natural sounding planar IEM that’s quite hard to achieve. I personally wouldn’t call it a direct upgrade over the original, but it offers a more mature tuning that’s smoother, with an organic timbre reminiscent of a dynamic driver. Soundwise, there are no major setbacks apart from it being a tad safe in tuning, though the large shell may make fitting smaller ears a bit more challenging. The included accessories are top-notch, making it ready to rock straight out of the box, and the noble cause of supporting the WDC foundation is the cherry on top. Amazing job as always, Hidizs.
I would rate this product 4½ over 5 stars.
