for me it happens on any EQ preset, the issue never happens when listening to music or youtube videos. It happens only on some games where a lot of sounds happen in the same time (war thunder, sometime euro truck simulator, squad) and when the headphones go loud i have to switch EQ preset to make it sound normal again (sometimes it doesnt help) or i have to wait like 10 seconds and they go back to normal again. I never had this issue, i played those games many times with my headphones but i think that after certain Icue update it broke and the issue started.
