The thing funzt really good. Wanted to have it up and running because cables annoy me here. Bin then lost in the summer, as it was really very warm. Result: You sweat at the things (at least I), so that one of the sweat quasi runs in the ears. Besides, I always hat the feeling that he does not sit on the right side and slip off the ear - which could of course at my right ear are (you are not quite symmetrical). In short, now I use it on the terrace and that's fine. Oh and running I have found another solution: a small Bluetooth receiver that I can clip it to my running pants front and from there the cable then runs under the shirt up to in-ears (does not bother not wobble around). So I need at least no interfering cables connecting the arm pocket of my smartphone to headphones.
