Hidizs MP145 IEM Review

[InfiniteJester]

Anyone get buzzing noise when plug the mp145 into pc/imac?

Whenever I touch the DAC dongle, the buzzing sound dissappeared, hence, I could able to use it on laptop/iPhone only

No buzzing for me from three different kind of dongle, the PC or the Steam Deck.

Anybody know a DD iem equivalent to the MP145?

I ask because, to my ears, the MP145s have pretty much everything I want--spaciousness, exceptional detail, low distortion, absence of congestion, great tonal balance with EQ. Except, I suppose because they're planar, their timbre just seems off to me, not natural or organic. I mean, I would never mix them up for the real thing. Folks talk about hearing a sound and not being sure if it came from their headphones or someplace else in the room--the looking-over-your-shoulder experience. That would never happen to me with the MP145s. They're really good, but I never fall into the illusion I'm listening to something live. As opposed to, for example, the HD600s, which sweep me away but are impractical for me most of the time, being open-back.

So, is there anything with roughly the same strengths as the MP145 but in a DD iem, which I am supposing would have more natural timbre, and in the same general price range?

You could try the simgot ea1000, I heard they're pretty similar, although ea1000 slightly more expensive.

That is true, the timbre is off, and it is perceptible with some music. Particularly, acoustic one. The SIVGA Que seem interesting. I haven't personally tried it, but all the mentions about their soundstage are positive: https://www.head-fi.org/showcase/sivga-que.27424/reviews

I use Apple Music, but I don't know what you use, so I'm going to share them through YouTube.

These are some of the many songs I use to test new IEMs and headphones.

I heard a much wider than normal sound stage on almost all of those with Arya Stealth Magnet headphones. Going to bookmark all of them. I'll have to try them again with the HD800S.

Maybe Kefine Delci.

Just got these in today. Best IEM I've ever heard. Used the default filter. Balanced pads, medium. No EQ needed.

I won't be able to listen to any of the other IEMs I have now. This blows them away by miles.

the MP145? have fun with it! what is your opinion in comparison to your Sennheiser IE's (I seem to remember that you have some)

The IE200s can't hold a candle to this one.

 

[herr.jemine]

good to know, nice that you now have an mp145, and nice that you are also enthusiastic

Among all the IEMs and TWSs I have right now, I've keep coming back to MP145 as it is much pleasurable to listen to. The best combination for me now
1. MP145 + Silver Filter
2. NiceHCK GrKing Flagship 7N Silver Plated OCC+Graphene OCC using 4.4mm
3. Pentaconn PTM01 COREIR (Brass)

It is because it fixes the fundamental mistakes present in Harman's target, it has bass and not just sub-bass and the ear-gain is relaxed instead of deafening. So it causes no fatigue while keeping a thick and delightful body.

This is a review, listening tests, EQ and detailed measurements of the Hidizs MP145. It was sent to me by the company and costs US $150.

The immediate impression of the shells is one of jewelry with its machined aluminum case. As you see, the included cable has 4.4mm balanced connection even though it doesn't need that (plenty sensitive to work fine with 3.5 mm unbalanced). Included in the case are three tip variants and nozzles (latter not shown):
View attachment 331069
As is typical, medium size tips match my GRAS 45CA measurement artificial ears best. But for listening, I have to go one size larger. I started with balanced tips but then tried to measure with the other tips. I found the process of swapping tips very difficult. The nozzle is large and the tips barely fit it. Good news is that once you get them on there, they going to stay. With some other IEMs I have had the tip get stuck in my ear while the IEM detaches! The measured difference with the three tips was very small. Given how hard it was to do this, I did not attempt to change the nozzles so the measurements you see are with the default ones.

The drivers in this IEM are planar magnetic which is a deviation from many others.

Hidizs MP145 IEM Measurement
Fitment on the headphone measurement system was quick and rather painless resulting in this frequency response:
View attachment 331070
As you see, compliance is very good except for some shortfall in treble region. Channel matching was excellent especially given the vagaries of getting IEMs to fit on the test fixture. Relative frequency response gives a chance for minor tweaking:
View attachment 331071

Distortion is exceedingly low:
View attachment 331072
It is basically non-existent at 94 dBSPL and hardly gets worse at higher levels. Here it is in absolute level:
View attachment 331073

Group delay is very clean but this is typical of many IEMs:
View attachment 331074

Being planar magnetic, impedance is flat and low:
View attachment 331075

Sensitivity is a bit low for an IEM but not the worst we have measured:
View attachment 331076

You should have no trouble driving it with many sources. Normal listening level on my RME ADI-2 Pro is around -45 dB.

Hidizs MP145 IEM Listening Test and Equalization
Initial impression was one of neutral present for the most part, lacking a bit of emphasis in highs. I could certainly live with this but why not apply some EQ to brighten things up:
View attachment 331077
I first created the right two filters. That gave the treble region more light but then the overall signature was too bright (even after I turned them down some). So I put in the shelving filter to bring up the deep bass. That nicely balanced things. To get rid of a tiny bit of bass bloat, I added the pink filter (2). Once there, the sound while not super different, was a lot more exciting for the lack of a better word. Sub-bass was impressive in its reproduction and how clean it was. Highs would sparkle and sometimes startle (for an IEM) the way they externalized. I sat there listening to track after track and could not stop. Eventually I did and took the pictures for the review, only to go back wearing them as I type this! The fidelity with this bit of EQ is just stunning.

Conclusions
The MP145 is a nicely made, good looking IME which comes very close to approximating our target (with its other nozzles, it may be closer). That makes it more than usable as is. A bit of EQ though, adds more flavor to the sound making it reference quality as far as I am concerned, putting a smile on my face on track after track. Yes, I have tested cheaper IEMs with similar experience but here you have another option made differently with some tuning at your disposal.

I am going to recommend the Hidizs MP145 IEM especially when used with a bit of EQ.

As always, questions, comments, recommendations, etc. are welcome.

Can someone please post @amirm 's PEQ settings for the MP145 ? Thanks!
