They look fine and are comfortable but sound is terrible. No bass whatsoever (I've tried with various songs and devices) and low max volume. I have a £30 pair of senneiser headphones which are much better, these sound like something that would come free with an mp3 player.
Picked these up yesterday at the Apple store, they didn't have any I could try but assured me that I could take them back if they were unsatisfactory, decided to give them a go based upon generally good user reviews.
Pros: lightweight and comfortable, cheap.
Cons: muffled sound.
Anyone whose ever listened to a good set of cans is going to be mighty disappointed with these headphones, there's a distinct lack of clarity that I found impossible to ignore.
Taking them back for a refund.
