Summary: Got these after reading other positive reviews. I'm no audiophile so I can't comment on response to different frequencies and all that stuff. They do fit well, they are comfortable, they work with my ipod and to me they sound just fine.
Summary: go through headphones about every 2 months due to excessive use at gym so tried these. cheap and very good quality. metal back with good fit, sound is smooth and clear with non of the excessive bass that spotty youths seem to like.
