Just bought one with a mic and 3.5mm for work because my new office has no meeting rooms and gave us a crappy headset.

I’m used to Soundcore liberty pro 3, self tuned the EQ and the Etymotic MK5, no tuning.

The Zeros sound ok, but not mind blowing like others mentioned. The vocals are a little recessed and sometimes guitars and muddy.

  1. Is this an issue with laptop output? I tried using the apple dongle and it didn’t seem to make a difference
  2. Am I too used to the very neutral Etymotics and not used to the more bassy mainstream?
  3. Burn in time?
  4. Not sure if it’s fatiguing, but I have tried it for an hour and feels like I don’t really feel like keeping on
  5. Does it make sense to EQ the iems?
