Disclaimer:

Good morning readers, Hidizs has finally launched a new planar, the Hidizs MP145 PRO, a sort of upgrade, if you like, of the Hidizs MP145, which are still the best planar IEMs to date. From my point of view, it’s more of a variant of the original model with improvements, but also with a different target tuning. A sort of more technical and mature version of the previous one, with two different tunings.

WDC’s sponsorship for the protection of whales and dolphins is back, and it’s always nice to see a brand partner with something to protect the planet.

However, the review will still be 100% honest and in no way biased.

I’m not an audiophile; I’m just a guy who 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.

Packaging:

The Hidizs MP145 Pro package is literally a cube, very minimal and serious, like the IEM inside.

The care taken with the packaging fully reflects the product inside and also shows how Hidizs continues to improve over time.

We have the following accessories available:

• Branded, jewel-like hard case with a spring-loaded opening
• Modular cable
• Lots of eartips: 12 pairs divided into 4 models, including the Anemone eartips
• 3 Pair of Tuning nozzles
• Manual & Warranty
• WDC gadget & brochure

The quality of the accessories is fabulous, and I have no complaints whatsoever about anything included with the new Hidizs MP145. The cable is high-quality, and the eartips are more than adequate as standard.

But the case has improved significantly. The previous model only had a bag, but we’re finally seeing a premium case on the Hidizs models too, one that’s actually larger than average.

Design/Build quality:

The Hidizs MP145 Pro remains a beast. The dimensions remain the same, but it’s thicker. The faceplate has a few extra polygonal details, but more or less, we’re looking at very similar shells of extremely high quality. I don’t think I’ve seen an IEM this well-made yet, even if you go up in price. The shells appear to have at least two vents, one before the nozzle visible in the internal opening towards the ear, while the other, I believe, is in the grooves of the faceplate.

Inside, we find a completely new 14.5 mm planar driver with several technical improvements that promise greater power, speed, and detail. I won’t go into the technical details, but with a higher density of copper coils, all this is possible. Hidizs IEMs with CNC-machined shells are all phenomenal, and this one also proves to be excellent, although I see it more as a more mature version of the previous one than an upgrade.

Comfort/Fit:

If you had problems with the previous one, these will be practically the same, although they’ve lengthened the nozzle and the structure a bit, so theoretically you’ll have a few extra millimeters. With the right eartips, you can bring the body more substantially outwards. It’s still a truly imposing IEM, a whale in an ocean of small dolphins. I have large ears, so I’d like to tell you that I have trouble wearing them, and I understand, but they seem to be made for my ears. Just in case, I tried different eartips besides the ones included, but I’ll give you some advice after my first impressions.

Initial sound impression:

The Hidizs MP145 Pro can be defined as a mature and more refined version of the Hidizs MP145, and for this very reason, at least from how I see and hear it, I would define it more than anything as a variant. In fact, Hidizs itself classifies them into two types of users, and if they asked me to put the first one in the drawer, I would tell you that I would not. At first impact, the New Hidizs MP145 Pro immediately demonstrates a superlative treble extension with an energy and sparkle that we do not have on the previous model.

The elevation and maximization of micro and micro details is evident; the listening experience becomes more technical and even complex in a certain sense. You leave behind that sensation of warmth and socks with trousers tucked in that you had with the first model and move on to a more refined outfit. The deep caveman soundstage remains, but is more blurred due to the greater brightness, which, in a certain sense, competes with the bass, which remains very present, but the quantity gives way to quality and even more speed. Fast, lightning-fast attacks. The perception of the soundstage has changed; if before it was potentially infinite, here we have boundaries, but they are extremely well-defined. Good amplification is required, but not excessively powerful, a sign that the driver is very efficient.

Tips Rolling:

The tuning differences are obvious, and this may lead you to try out multiple eartips to adjust the bass or treble.

They can be used with either a deep or shallow fit, for better or worse, and for some, the only alternative will be to use larger eartips for greater comfort. In my case, I’ve tried several eartips, including Dunu S&S, Divinus Velvet & Wide Bore, and Soundcoon, and I have to say that overall, the Hidizs Anemone, with this new model and structure, offers remarkable stability and comfort, but above all, they manage to balance the sound and the soundstage well.

Equipment used for testing:

Device:

• Mac Mini
• Redmi Note 14 Pro 4G

Software:

• Amazon music UHD 24bit 96khz (Both)

DAC:

• Creative X5
• Fosi Audio K7
• Hidizs AP80 Pro Max (review incoming)

Final sound impressions:

The new driver and tuning prove to be a winner on the Hidizs MP145 Pro; I’d say that after a long time, I’m finally hearing a driver capable of fully exploiting the entire frequency spectrum. To put it simply, the new version has a treble extension that’s pushed to the limit, almost razor-sharp for a spicy finish; the tuning significantly favors the mids compared to the previous model, which are much more vivid and energetic, more engaging and prominent. I’ve noticed after several albums that they don’t lose badly recorded tracks or poor quality files.

It has such energy and vividness that it easily impresses the listener, track after track; the mids, in particular, are well-crafted, with particular attention to the musical instruments, each of which is perfectly positioned. Note the uniqueness of instruments like guitars, which sound vibrant, almost as if they were live.

It’s generally a brilliant IEM, so I think many will opt for the nozzle, which promises a warmer response, but we’ll talk about that shortly.

Tuning Nozzles:

Visually, the nozzles don’t have many differences, probably only the final mesh has a different density.

• Treble – Silver: Since it’s already bright, this nozzle is especially suitable for certain genres of music. In fact, for my predominant musical genres, this nozzle is best suited for classical music, to give that extra boost to the instrumental part. Otherwise, it might become too spicy and difficult to listen to, especially in medium sessions.
• Balanced – Rose Gold: A good middle ground, particularly suited to pop music, keeps the sound balanced with an eye on the treble, which, on some tracks, can occasionally be a little sharp, especially if some pop tracks also incorporate a bit of EDM.
• Bass- Red: My favorite is definitely the red, which smooths out the treble peaks a bit and keeps the sound extremely crisp and detailed. It’s all there: the differences are minimal, but that little bit of smoothness on the high notes helps, especially with the genres I listen to. Bass presence is slightly improved.

Bass

The bass is much more controlled, less elevated, but when the treble fades, it’s overpowering in the background with excellent, dense subbass that recalls that of the first version, but the cavernous soundstage that the bass created on the first version is gone. This is why I don’t think it’s an upgrade but simply something different. With this one, however, the bass is extremely quality rather than quantity, very fast, composed, and elegant. The dense, warm sub-bass is beautiful.

Mids

Less bass? Less warmth and more liveliness on the mids, which become much more forward-looking with a whole new energy and vivacity compared to the past. Particular attention is paid to the instrumental part of the tracks, demonstrating surgical precision in detail, separation, and accurate positioning. Undoubtedly, the mids have more mature and refined frequencies.

Treble

The Hidizs MP145 Pro takes treble to a whole new level. They’re very extended and pushed, with extremely high resolution, rich in micro and macro details like never before. The amount and extension might not be appreciated by more sensitive users at high volumes, but fortunately, this IEM is listenable even at low volumes without sacrificing frequencies. On some tracks, especially if poorly recorded, the treble becomes very sharp, although still at a tolerable level for my ears. There’s no shortage of crispness and air, in fact, the perception of air has increased.

Soundstage and Imaging: 

We’ve moved from caves to something more like a real soundstage, with greater accuracy and realism. These are two types of soundstages, both truly expansive and well-crafted, with improved separation and mind-blowing layering capable of creating images with unbeatable clarity. You’ll notice it when you listen to a well-recorded music track, as it’s very susceptible to file quality.

Comparison:

Vs Hidizs MP145

The Hidizs MP145 OG is not interchangeable in the sense that it offers a different tuning that has its own audience. It’s an evolution that diversifies them for a different type of user. Both have a lot to offer, which is why I don’t feel like recommending one over the other because they’re both phenomenal.

If you look closely at the images, you’ll see that the main differences lie in the structure of the shell facing the ear; specifically, the nozzle is elongated, allowing the bulky structure to sit further out and better fit even the smallest ears.

Vs Sivga Nightingale Pro

Another pleasant offering comes from Sivga, which adopts a less warm sound than the Embers, but still more mature and balanced with a good amount of detail. The Hidizs MP145 PRO, however, has a more mature tuning that aims to bring greater detail and purity.

The Sivga Nightingale Pro is still well-made and is the most compact in terms of shells, and you will have no problems even with small ears.

Vs Letshuoer Ember

Aside from the price, which is very important, the approach is super warm, almost the opposite of everything. I can say, however, that they are extremely smooth, and if you’re sensitive to treble or lighting, they might be right for you. They’re more human in size, but even though they use similar technology, they can’t really be compared due to the price difference, although in terms of build quality and audio quality, in my opinion, we could simply be talking about different tuning.

Conclusion:

Hidizs is a brand I’m particularly fond of, as the decision to start reviewing audio products was born thanks to them, with the opportunity to review the Hidizs MS5, and I’ve continued ever since. Seeing the brand evolve over time, and especially the products I love most, makes me happy. In the case of the Hidizs MP145 Pro, they wanted to maintain a similar design with a few small aesthetic improvements (details) and perhaps a few small changes in terms of shape. The shells are reminiscent of whales and honor their collaboration with the WDC, which I really appreciate as an initiative.

The old MP145 was a more fun version with that cave-like bass and very deep soundstage, while the new ones are more mature and inclined to a more natural and realistic sound, with a good dose of treble, followed by a ton of detail and also well-crafted, very lively and present mids. I don’t think I could decide between the old and the new because, being different, they fulfill two different roles. We can absolutely confirm that the tuning has undergone a notable improvement and maturation compared to the previous one, and we can currently consider it a reference.
