- makes sounds noticeable that arent noticeable on speakers or cheaper headphones. so you hear every bad thing in low quality audio
- bad.. just BAD. so bad something must be wrong.
- there is an slight echo with no apparent way to turn it off
- none of the presets make anything sound good
- messing with all the equalizers and options doesn't help
I think the problem is a combination of low quality audio and untuned equipment.
