I bought these headphones for jogging with the iPhone, among other reasons because they are sold with the attribute "sport" and the logo of the partner adidas. From my perspective, they will not do justice to this claim: 1. Only the description in the packaging (ie not outside) stating that they "get wet to protect" are. I beg your pardon? Earphones which are intended to be suitable for sports? This is a joke and you feel as a customer kidding. 2. The headphones sit by the soft strap too loose and constantly slipping while jogging out of the ear canal (no matter what size the enclosed adapter). 3. When you copy purchased the microphone was broken and had to be exchanged. All in all, I am disappointed by the product, price / performance is not satisfactory for me. I definitely would not buy it again.
