Mi Sound Enhancer Not Working

[Boar_Sebastian]

Hi! After inserting the headphones in the phone, the mi enhancer becomes active. But it doesn't matter what preser I choose or if I modify the equalizer I get the same sound from the headphones. Tried different types but the results are the same.
I'm one Xiaomi eu 7.2.9.

Installed the newest ROM, but there is no improvement.
