I was very excited at the beginning of the sound and the maintenance of the headphones and have worn this for a jog and also general sports. Once I started to sweat and sweat when I say, I mean it like monsoon rains. These are already the second headphones are no match for my perspiration. The sound was distorted and the call acceptance and music control button has denied his service completely and after a month. I'll send the item back.
For people without a lot of sweat flow an ideal solution !!!
