Query: alright

pros: great sound, comfortable, closed headphones: when you put these puppies on you can't hear ANYTHING apart from the music, also it's hard for outside world to hear you even when you're rocking it.cons: i'm already on my 3rd pair because of the same problem: after about a half year of abuse (i.e shoving them in my backpack) one of the speakers stops working. for the life of me it happened with the first two i had. so i now bought mdr7506's which is basically the same but priced more (go figure). i think sony should make the v6's more tough though. throwing headphones into a backpack is a pretty important thing.
