Closed. I'd like to keep my music to myself (it would seem the grado's could irritate others in public, for example) Durable. I read a lot of reviews off headphoens and they talk of the plastic being fairly brittle and shitty (sennheiser 280's seem to have this problem from what i've read) Comfortable / built for a large head. I have a big head. That may make a difference. About $90. A little less maybe, a little more maybe. Roughly 90 bucks. Obviously sound quality is important; i don't want something that sounds terrible. Any recommendations? i'm really at a loss.
