Noise in Mi5X headphones, how to fix?

Maybe this is the firmware? I know that firmware is perfect, but nothing is perfect. You can give a link to the firmware without such a problem, please ((
I actually use the beta version 8.11.1 (I haven't updated because I read some problems) and no problems, you should try making a clean flash installing the official China rom (without locking bootloader) and try again with 8.11.1 version
