The-ear headphones are pretty solid, although we can forgive because the bass when listening to music are present, even a little too much, as many of today's helmets ... in maintaining these do not move, a small box is provided, to allow the transport, use one! I had the misfortune not to use it 2 times, and after the second time the left ear became almost inaudible, probably due to a crash of the cable, even if it does not excuse the failure! So good advice: Protect them with the little box provided.
