Using my headphones specifically over USB with the Zenfone 8 I get really bad sound, i.e. sharp and very inconsistent treble (random dips & peaks), muted mids and bass. Almost as if everything is being played over an old telephone, especially since only the vocals sound kind of OK. Listening via Bluetooth it sounds normal, so the problem is limited to USB audio.
Given I had similar issues using my FiiO BTR5 DAC over USB in the past, I am pretty sure that the phone is the problem.
Does anybody know a fix?
