Interestingly, as a YouTube reviewer has spotted, these are most likely made by a more experienced Hong Kong company called OneOdio. Specs and form factor seem to be rigourously the same as those of the OneOdio Focus A5: https://www.oneodio.com/products/oneodio-focus-a5-hybrid-anc-headphonesThat's impressive for $25, still good at full price.
I have a few UGreen bits and bobs, USB cables, chargers and the like and so far they've all been good.
I also have a little USB headphone adapter, which cost around £12.00, I think. I haven't really tried to compare it seriously to my desktop amp, but it sounds fine to me.

Better use these parameters:Hello everyone, can anyone tell me if these is the EQ of Amir for Max5C. Because in Band 6 there is any Q Factor right? Also what Preamp should I add? Thanks View attachment 417253
Thank you I already use these two EQ profilesBetter use these parameters:

UGreen Max5c: $25 NC Headphone Review
This is a review, detailed measurements, listening tests and EQ of the Ugreen HiTune Max5c noise cancelling wireless headphone. It is on kind loan from a member and is on sale for $25.47 (retail $57). The Max5c feels every bit as high quality as much, much more expensive wireless headphones...www.audiosciencereview.com
They include appropriate Preamp values.
Hello @sulfuriq can you tell me if XM4 Max 5c sound quality can be compared to Sony XM4 as I see you owned. ThanksOk try to go to Device Manager, go to Bluetooth and uninstall the device then restart the pc
View attachment 413897
It should start with the Windows Standard Driver. Is the Bluetooth device built in or an adapter? If its an USB pull it out from the USB port then reinstall it after restart the PC
IMHO XM4 has better SQ compare to Max 5c as you can play around with the EQ in more depth.Hello @sulfuriq can you tell me if XM4 Max 5c sound quality can be compared to Sony XM4 as I see you owned. Thanks
I know but the Max 5c with LDAC and EQ can be near to an XM4 out of the box?IMHO XM4 has better SQ compare to Max 5c as you can play around with the EQ in more depth.
Not sure about that since been years had XM4 out of the box and I only had it for convenient and those Max 5c I've bought it for the wife and the boys while my daily rig is the Sony MDR-M1 and Edition XS. Just enjoy it if it suit your preference.I know but the Max 5c with LDAC and EQ can be near to an XM4 out of the box?
@amirm the last PEQ does have a Q factor, I used 1.
If it is not then the score for your EQ is inaccurate.
Usually, BT SOCs provide plenty of EQ capabilities including Dynamic range compressors, therefore the tuning should represent the intent of the designers.
Here are some thoughts about the EQ.
Please report your findings, positive or negative!
Notes about the EQ design:
- The average L/R is used to calculate the score.
- The resolution is 12 points per octave interpolated from the raw data (provided by @amirm)
- A Genetic Algorithm is used to optimize the EQ.
- The EQ Score is designed to MAXIMIZE the Score WHILE fitting the Harman target curve (and other constrains) with a fixed complexity.
This will avoid weird results if one only optimizes for the Score, start your journey here or there.
There is a presentation by S. Olive here.
It will probably flatten the Error regression doing so, the tonal balance should be therefore more neutral.- The EQs are starting point and may require tuning (certainly at LF and maybe at HF).
- The range around and above 10kHz is usually not EQed unless smooth enough to do so.
- I am using PEQ (PK) as from my experience the definition is more consistent across different DSP/platform implementations than shelves.
- With some HP/amp combo, the boosts and preamp gain (loss of Dynamic range) need to be carefully considered to avoid issues with, amongst other things, too low a Max SPL or damaging your device. You have beed warned.
- Not all units of the same product are made equal. The EQ is based on the measurements of a single unit. YMMV with regard to the very unit you are trying this EQ on.
- I sometimes use variations of the Harman curve for some reasons. See rational here and here
- NOTE: the score then calculated is not comparable to the scores derived from the default Harman target curve if not otherwise noted
OK L/R match.
I have generated two EQs, the APO config files are attached.
For the price it could be a nice way to experiment with EQ etc.
Score no EQ: 66.6
Score Amirm: 89.1 (great effort)
Score with EQ: 99.1
View attachment 407913
Just for the sake of it I used Amirm's EQ as a starting point as it had most of the EQ points.
The issue is that the the score optimization requires the regression slope to be as close to 0 as possible therefore it decreased the LF to achieve this.
It probably not as good as the one above for most people for this reason, it illustrates the issue with solely optimizing for the score.
Score no EQ: 66.6
Score Amirm: 89.1
Score Amirm optimized: 100.9

Below are EQ presets for the XS.Has the same been done for the Edition XS?
Have you tried it with the EQs here? Play some Lose Yourself to Dance, High Water Everywhere (Live from the RAH), Starboy etc and let me know.Thanks for this review, Amir. Looking at it, seems like a lot of value, but obviously going to be missing sub bass, no matter what. I think I would rather have put in a high shelf at 3k of +2db, and, since I'm kind of a bass head, just added a peak filter at 150 hz to bring up that trough so it was level with what comes before and after. The only problem is the mid range distortion and resonance, but it's still about 40 db down from the signal, so it's about 1 percent there, really not that bad IMHO. So. really. if you can eq it, and given the other stuff like a mic and noise cancelling, it seems like just a stupid bargain at $20.
Easy to see why you recommended it.
Hi @velasfloyd : these UGREEN do not have a 3.5MM jack. They do work in DAC mode connected via USB-C. I can confirm you can transit through different noise-cancelling modes while connected in DAC mode as well, though I trust this will only be helpful if you are watching content on your laptop / tablet / mobile device.can you, some owner, please tell me if I connect this wired, can the noise cancelling still be on?
I am interested in flight use.
with my sony xm3 I can see the movies in wired mode, and noise cancelling on.
But on my anker L30, as soon as you connect the cable, the headphone gets off. so the noise canceling cant be used.
This is not convenient to use in an airplane.

Connected via DAC, you get audio up to 32bit/192kHz, at rather decent volume. Though @CedarX had identified a DAC with apparently lower specs, Roon tells me DAC here appears to be a different one. The headphones sound amazing in DAC mode, especially using @Maiky76 's EQ above.
Since buying the UGREEN, however, I have passed them on to my son and got an Edifier W860NB Pro to replace my old Sony WH-1000XM2. These are the Chinese version of the Edifier WH950NB. I got them at USD60 on Taobao, which is a steal considering the original price of the WH950NB.
While I love the UGREEN, I think the Edifier sound a tad more full, well-rounded, with a wider sound stage and very good detail retrieval (more so than my Sony). I also really like their build quality: like a thick, soft rubber, very nice to the touch (note that the Chinese version does not have the shiny metalic accents at the hinge that the international version has). It is a rather elegant set of headphones, though the UGREEN also look quite the part. My son actually thinks the UGREEN look better.
The Edifier also work in DAC mode -- unlike I had read in reviews of the WH950NB -- and there they get MUCH louder than the UGREEN (I need to stop at 30 on Roon), without distortion. It appears thus that the DAC/AMP here is a quite more powerful one.
The Edififer also has a 3.5mm jack (and I can confirm noise cancelling also works once you turn the Edifier on while connected via the 3.5mm jack -- as it does in DAC mode) and comes with a really nice and expensive-looking case.
While both are reasonably cheap and sound great, I think you get better value from the Edifier.
I agree but since we can easily eq every headphone the real comparison should be with equed wired headphones. In this case I am not so sure we could find this superior to many modestly priced wired headphonesI guess the real point is trying to understand how many passive headphones would be outperformed by this one, and until what pricepoint.
