This isn't a problem unless you're listening more loudly than you should for any given situation. Both my PK1s and ESW9s are boss approved, but only if I'm not stupid with them. I know I need to somewhat hear what's going on around me, so I don't turn the volume up. That's one advantage to getting better quality headphones and pairing them with a good amp. You can still listen at low volumes and hear what you want to hear in the music. Crappy headphones require more volume to give the illusion of quality.
