I was looking for headphones for my iPhone to listen to music, mainly, and pass calls, on occasion. Aesthetics is a success, but his party is not left out, even though I am not a specialist in sound waves (say, compared to intra-oriculaires helmets, no photo) . The closed helmet side is excellent, in the subway, outside noises do not bother listening. Small problem: when we walk with anything other than sneakers, it resonates in the ears, so the insulation is good ... Another downside: the remote control does not run iPhone truly possible. We find the button play / pause / skip usual, but the volume is managed by a slide that is not connected to the iPhone. It's been a little cheap, but with use, it's not really embarrassing. See over time the cable behavior indeed avoids knots, but may seem a bit fragile and as we can not change it, it can make a difference. In any case, at present, I am perfectly satisfied.
