Good morning,

A little review of the new " Hearing compensation" function:

- first you have to remember to put on OFF before the test everything in "Effect », « Crossfeed » & « HP EQ », juste keep « Hearing compensation » ON


- once the "Hear Comp" procedure is launched, found at the end of scrolling "effects" only on the X9, once the test is launched and if I stay a few seconds on the first explanatory page and wait to hear the frequency before pressing "hear", most of the time the screen changes to arrive on the last "vu-meter" used of the X9, after I can see on this volume the frequency increase, but I can no longer do a validation action or other and I have to get out of this " Hear Comp" and start again at the beginning (bug to be corrected so).

To avoid this bug, once the "hear Comp" procedure is started, as soon as I see the 1st screen I validate the "Heart" button on the right then on the 2nd screen I can quietly choose the dB threshold where I hear very very slightly the frequency and validate.

In this way I can do the test of the left ear, then right and lead to the final page that must be quickly validated (do not do the rename that can be done later, otherwise the vumeter comes back and you have to redo everything).

If we quickly validated the test on the last page showing the compensation curves proposed for the 2 ears, at that time the "Heart Comp" was memorized, we can only for the moment on the X9 put it on ON/OFF

To have both the " Hearing compensation" function and the other options of the X9:

- I'm coming out of "bypass Off"

- for my part I put the "stereo Width" back on (modifiable percentage and mute available on the remote control now, it's really happiness)

- I put the "HP EQ ON", at this time I have my personal hearing corrected upstream with the headphones used to memorize the "hear Comp", and I can either listen to a memorized EQ just "flat", or finally put one of the EQs found and memorized via the listing proposed by Luxsin, in this case, having done this morning the "hear Comp" on my Hifiman Arya Organic (all my previous personal EQs memorized are no longer good, too clear and aggressive, so logical with my "hear Comp" now validated before The EQ of the X9), but those proposed by the Luxsin X9, in particular the "Hifiman Arya Organic Oratory 93" are now very consistent, and we will finally be able to calmly test all the EQs offered in the Luxsin helmet listing.

——

For a future update, I would of course like to be able to put on or OFF the Hearing compensation via the application by means of a key on the remote control by programming it in the "general" page of the X9, then "key setting", "remote control"

Whether the bug during the test is corrected, or whether the first page on the two pages proposed for each frequency is removed, it is certainly informative, but repetitive with the second

Of course I would like more frequency band for this "Hearing compensation", especially from 2khz up to 6khz, area where most hearing loss are net as we get older in particular

I would like to have access to the corrected frequency table seen only during the validation of the " Hearing test", to be able to compare the corrections according to the headphones used with an « Hearing compensation ».


A thousand times thank you for this obvious and necessary function, absolutely everyone needs a " Hearing compensation", regardless of the age and health of our hearing, very few people have a perfect ear, and the abusive use for the latest generations of headphones and loudness War among other things on the music listened to will not improve this growing problem of hearing deterioration of humans.

Thank you for detailed feedback and suggestions.

Regarding the issue where the screen automatically returns to the VU meter during the hearing test, we believe this is caused by the Back to Home function being enabled (General → Back to Home). When this option is enabled, the X9 automatically returns to the selected home screen after the configured timeout, even if you’re in the middle of the hearing test.

As a temporary workaround, please try disabling Back to Home and run the hearing test again. We’ve already identified this as a bug and will fix it in the next firmware update so that the Hearing Compensation process won’t be interrupted.

We also appreciate your other suggestions, including remote control support for Hearing Compensation, additional test frequencies, and access to the compensation curve after the test. We’ll pass all of your feedback along to our product team for evaluation.

Thanks again for your valuable feedback and for helping us improve the X9.
 
Thank you for your answer and the incredible scalability of the first Luxsin Premium device, I use it not only for my personal pleasure, but also now as a professional audio interface tool

Thanks to your "Hearing compensation" option after mixing last week a musical documentary, and for the viewing with the director and the producer afterwards, I was able to perform their audio calibration of auditory compensation to all 2 and they were thus able to listen to my mixing with their "corrected" auditions, so get closer to the final work I did, one had a big loss in his left ear, and the other, former musician with a lot of concert made saw how much he had lost dB between 2k and 8khz, he listened With or without " Hearing compensation", and his listening with the option was very positive, he Even rediscovered his music.

Even if it is still far from being a perfect function and above all very precise for the essential frequencies of corrections (necessary levels every 500hz between 2khz about 8khz), this brings everyone a real auditory change, before any voluntary or not use of the HP EQ function of the X9 to use the proposed curves or create your own personal PEQ from scratch if you are looking for more bass, mids or clarity and aperture in the treble and of course depending on the headphones.

Looking forward to seeing the rest of your proposal on already the X9
 
I've never used PEQ before, really, and I don't understand it. In a discussion of the Wiim Ultra's PEQ capability in a Reddit thread, one user wrote:
"The PEQ filters on a WiiM are simple IIR filters dealing with tackling the frequency domain only, these IIR filters are non-linear and can introduce their own phase distortions which can be more audible than the issue it's trying to correct."
I looked at the X9 manual and I don't know how to see if the X9 PEQ operates according to the same principles/limitations (?). Just curious if an old hand who knows the X9's PEQ can set me straight: is it more flexible than the Wiim's PEQ, as described? If the potential pitfalls are the same with the X9, is there something I should beware of when EQ'ing, re: these phase distortions? In case it matters, I'd most likely be doing this with speakers, using the X9 as a pre.

Does anybody know what the maximum input (V RMS) is on the rca analog inputs for the X9? I can't seem to find that data anywhere.

The X9's RCA analog input is designed for a nominal input level of 2.1 Vrms.
