A few days ago I tried my Z-680s on full volume since having them a yr ago. All I can say is "wowww and never again". After a few secs on full vol, the sound quality was still very clear but my ears gave up and sounded all muffled and they were getting worse (like in a night club but much worse) ouch..
But it had to be done sooner or later.
