These headsets do the job. They are perfectly maintained in my ears (which is not the case of the atria of the iphone for example), and delivered sound is okay, enough for the sport anyway. The remote control is convenient and strong enough for her not to push it thoroughly. Small flat on the clip that does not take the masses and is not practical. A real clip to prevent the wire (long) does not balance too would be a good improvement. But in the end I recommend.
