I was at the Bose store at the Mall of America yesterday and listened to the best headphones they had on display (some $300 noise cancelling cans). Needless to say, I was surprised! My $70 Grado SR60s are head-and-freaking-shoulders above those Bose headphones in sound quality. The goober employee comes up to me after I listen to the Bose cans and says, "Sound pretty good don't they?" I just glared at him and said "No, they don't. My Grados kick the $hit out of those things" and walked out.
Moral of the story: research your purchases. It really works well.
