Bought these for my kid (the one who likes the noise isolation.. the others prefer the MDRE9LP type. The isolation qualities are great, I have to holler to be heard, yet he says they are not turned up loud. They are very comfortable and durable and the cord length is just right. They are used for several hours every night (while he's doing homework or watching videos on the laptop) and he is well pleased. As I mentioned in another review, breaking of cables is fairly common in the relatively cheap models of headphones, but these haven't had any problems so far (so good).
