Item received on time, no problem about that ... By cons, these headphones are hyper sensitive to cold in the morning 1/2 headphones never works ... This is not an isolated case since I have a friend who has the same in black and has the same problem. There is also a problem in ergonomics, the listener that one should not go behind the blow means to turn his head without getting shot by that ear ... Otherwise the sound quality is impeccable.
