These headphones are supposed to be the top for sports ... Good joke, they do not even take a tour of the stadium (300m), the sweat makes the graves, maintaining system is clearly poorly thought. I have not even kept three days so it was not good. For the money I invested in powerbeats 2, nothing to do is the day and night. Y'en so sick of these companies that are trying to catch people with super athletes appear in full action to try to sell bad products designer. Finally I saw in musuc rooms, but they show the good runners. I runner, you thought to these headphones? Run away !!!! Fortunately Amazon has an ultra reassuring return policy. Thank you to them.
