Hidizs MP145 IEM Review

Could you kindly clarify?. What do you use to apply Dolby Atmos audio DSP processing, to these IEM's? Thanks
I came to the same conclusion. The improvement in headphone quality, in my case a bottom bargain basement CCA CRA (2023 revision) that no one says anything special about it, with a little bit of broadband EQ, has become a revelation. The good stuff, well produced music, sounds AMAZING, and the really good stuff sounds INCREDIBLE, and many things that I once thought were amazing, it shows them for exactly what they are - the music may be great but the recording and production not up to scratch.
Example is Englishman in New York - Sting, a wonderful composition, but on critical listen, you hear the shortcomings in the recording and mixing/mastering. It is still a masterpiece, just not a sonic reference, when heard through highly resolving headphones/IEM's.
I must add, there is a lot of very good music out there. So please do not despair.

Yeah, the HPF function may limit you're enjoyment of electronic music with super deep LF sounds -- but I find it helps with definition of other bass instruments when I'm playing things somewhat loudly - especially well recorded bass guitar, acoustic double bass, and definition + dynamics of kick drums, but I guess it's a trade off...
But I'd also make the same observation when using a high quality sound system, using a HPF at a very low frequency can help bass definition by reducing bass distortion in the speaker and reducing the stress on the amplifier driving the speaker...
No. I haven't researched the differences among the nozzles. Will do today. I did increase the Q to 1.5 and reduce the peak to 2db.
Has anyone face or knows about the MP145 tuning? A short time after the release the Hidizs change the tuning as I read.
I guess, I gonna wait for MP143 or any budget option if anyone knows that could match the "first" sound of MP145.

Interestingly, Hidizs has opened a “challenge” for the IEM graphers to actually measure this tuning difference.
I don’t know if they are dubious of the alleged tuning change and are looking for evidences/details… or, there has never been any change but Hidizs is open to the challenge, and want to prove it.

I wouldn't know the difference since my unit new. You'd have to have one of the first releases, a new release and a measurement device.

As far as my unit is concerned, I like it more than the Timeless.
It's going to be interesting what comes out of this challenge. The speculation about the tuning has done a lot of damage to them and they weren't proactive enough and quick to respond in my opinion.
It is a bit of a pity that allegedly Hidizs has modified the design, and whatever is now available in the market, for the MP145 IEM, is NOT or may NOT be exactly the same as whatever Amirm measured.
So hard to make a buying decision, when manufacturers do this, without sending out the revision to be evaluated. They save money on marketing, but this F's Up the buying public, who don't know what to do. And it makes a nonsense of all effort to measure devices, when the manufacturer does a silent revision, and tells no one of it.
Sad.

It would have been so much better for HIdizs to send this new version to reviewers we trust, but I can imagine they are trying to save on "marketing" costs, which is where the cost of sending out a whole batch of IEMs to reviewers, will be assigned to.
I've had two of my IEM purchases leave a bad taste, a CCA CRA and a KZ ZVX, which I discovered only after purchase, had been silently modified after they had been reviewed and measured by lots of influencers. Sorry I cannot go ahead and buy an MP145, which has not been reviewed - i.e whatever I buy now, did not get any opinions from reviewers. And that includes AmirM's review here, on this thread.
We simply do not know what we are buying. Not a great position to be in, Who knows how many of these silent revisions occur in the same product.?, over time.
Not trying to defend Hidizs, but is this the change we’re talking about?
I took this graph from a reviewer who recommends an absolute “do not buy” because of this alleged change.
Based off Amir’s measurements, @Maiky76 calculated a score with no EQ of 77.0. With this “change”, what is going to be the new score? …76.8, slightly worse… or 77.2, slightly better?
And if you EQ to your preferences, which I always (try to) do, does a slight change to the baseline really matter?
I have not listened to either of the versions. And thank you for posting the comparison graph. My main point was not about the sound quality of either version, but about the reality that many who buy, will not be aware, just as I was not aware when I bought 2 IEMs from CCA/KZ.
It would have been so much better to release it as a new version, and call it something different. For the sake of people like me who have no measuring tools, and rely on publicly available measurements to "tune" our IEMs based on these measurements.
All attempts to EQ my IEMs, with any iota of accuracy, because they have been revised and I have no clue what their EQ is, is now a futile effort. I cannot EQ them precisely, cos I do not have the information on which to base any such effort.
In my case I have not found the Frequency Response measurements for my revised IEM's.
That's my point, and however good or bad the revision of an IEM is, such silent revisions, limit my ability to improve it via EQ. Hope you get my point.

If anything, the second graph is better. Consider unit variation and margin of error and you can probably explain everything about this alleged revision.
The only reason that I do buy the MP145, the silent change.
And I agree that it is the reputation of the company that did not tell about the change. EQ is not always the solution.
I want to listen bit-perfect from the streaming service without the possibility to eq etc...
I hope MP143 to be the right iem for Hidizs.. But the damage has been done somehow.. And would be good for the audio community to talk about similar company changes, so as to protect us first and make the company be better and not just to believe that they sale whatever they want.

Any detected change is still dishonest and damaging to the brand. Reviewers and users shared both objective data and subjective impressions of the original product which are no longer valid. Unless they launch it as a new product and with some naming distinction like MkII.
Nevertheless, based on a comparison chart, I just viewed a few minutes ago, from a reviewer whose opinion I trust, I'd still buy a revised MP145, if it was within my budget. See link to comparison spreadsheet below. His opinion is spot on with the graph that was posted earlier. Revision, according to him is more neutral. - That's from JaysAudio on Youtube.

Why?
1. It still represents good value for money, if you have that kind of money to spend.
2. In my case, I listen predominantly in an environment where it is easy for me to use EQ.
3. Any EQ I add is in small doses, so even without it, I would expect the IEM's to be pretty close to good enough.
4. Our ears adjust. But it's better if the headphone/IEM is closer to our personal preference in the 1st place.
5. If I bought from a seller that accepts returns - fantastic, just in case I do not like it.

this is a drama again, oh dear - this IEM is very inexpensive, and excellent - if some guy publishes a video with some claims that are not checked and confirmed in any way, it is extremely damaging for the manufacturer - the people who do not own this IEM and are upset about it are just talking bullshit
Maybe I got lucky. I still love the silently revised KZ ZVX, which is now my daily driver and represents amazing value for the price, in spite of my objection to the business practices of KZ.
So I'm careful, from my experience, in spite of the fact that I have no clue what the real frequency response of my own copy of the ZVX is, to not throw that baby out with the bath water.
Judging the IEM, on its own merits, I would still highly recommend the KZ ZVX - it sounds fantastic, best listening device I have ever heard, for all of $15 max(including postage and taxes).
Which is why I'm leaving an open mind on the MP 145. Must add though, the MP 145, is way above what I would be comfortable to spend on an IEM, at this point in my journey with these things.
I am extremely satisfied with the KZ ZVX, judging it by its results - phenomenal listening tool, and I can recommend it as a blind buy for anyone who likes a neutral presentation, which also responds well to any EQ to bring it closer to your personal preference. ONly downside is - I have no clue what its frequency response is, cos I have no measuring tools, for IEMs, so I cannot truly EQ it.
Based on how great the ZVX sounds for to you, it must be very close to your ideal FR. Unless fit, actual or perceived built quality, cable quality, etc. are an issue for you, I doubt the MP145 will bring much in your case… It could end up being much worse for more money!
This is the thing with KZ/CCA: they are trashed for having way too many models, with tuning/FR that are all over the place... This is forgetting that each one of these models is the perfect IEM for a certain group of people. My biggest critic of KZ/CCA (I own several), is they give you no hint as whether a particular IEM will work for you or not.
Manufacturers who follow Harman work at least target “the majority”, the largest group. The MP145 (either version if there is such thing as two versions) is in that camp.
Any kind of transducers have a number of different customer segments.
1. Anything as long as it makes a sound. Some people just do not bother, cos audio quality is NOT their priority.
2. Discerning customers, who have a preference for how they want to hear their sound - bassy, neutral, bright. relaxed, detailed huge or small soundstage, etc, etc. Me I prefer as much detail as possible, without being overly bassy or shouty, possibly a slight V shape or small U shape, unfortunately my two IEMs are the revised versions (CRA and ZVX), so I have no clue what their measured shape is!!., cos there are no specific measurements out there confirmed to be that of the silently revised versions.
3. Budget conscious - wanting the best within a budget.
4. Money no object - ready to spend a lot to get what they think is the best.
These customer categories would apply to IEMs, traditional over the ear headphones, speakers, DACs, headphone amps, etc, etc.
I have an ARTTI T10 on order, in transit, and so look forward to receiving it without any surprises, such as quality control issues. I was not convinced about the planar magnetic products from KZ/CCA, and got a small over the usual discount, which pushed by buttons to get the ARTTI T10.
The one thing missing, which would be quite expensive, or time consuming, to establish, is a comprehensive database on IEM measurements and reviews. About time a wikipedia for this was established, happy to start one, even though I know not much, and hopefully others will add to this and improve it, and keep it updated.
I have 6 earphones I bought in the recent 9 months (some are a bit to embarrassingly terrible to mention after I listened to the KZ ZVX), which I may never listen to again, but I cannot be the only one, who has had to sink some money into trial and error because it is hard to grasp the IEM world, as a newbie). So many misconceptions - I once thought Linsoul was a manufacturer!!, not the retailer which it is.
If only there was a way to limit the number of products that one has to buy to develop a personal reference/comparison method, of finding the best IEM for self.
The one thing that is almost always true - if one disregards frequency response, knowing the timeline of IEM product launches, in the history of IEM's is important, as driver technology and tuning keeps improving, in clarity/resolution/detail. Most of the time, no point buying things released older than 3 years prior. Ideally no more dated than 2 years prior.
For the measurements repository part, AutoEQ (https://autoeq.app/) is pretty great! It also neatly addresses the very nature of “targets” and individual preferences.
Why Amir’s measurements are not listed in AutoEQ? Because there is a minimum standardization required on the measuring side to make the website “crawlable” and the data “usable” by the AutoEQ automation scripts.
I wish somebody with knowledge and time (I have neither) could tackle this…
