My actual search began with a headset for sports. After some search, I have been interested in a OnEar variant. Here I have a really good price / performance ratio found. The possibility of a cable when the batteries conk out is really great. The supplied cable seems a bit cheap. With Amazon but you can create a quick remedy. The bass feeling can not be compared, in my view with the one ear. Clearly, the full sound for me. May well give it the equipment that your job even better. These are but considerably from this price segment. On the subject of the use of sports ... the comfort is very good, you do not press and hold but very good. (Even with quick movements of the head) Voice quality if you'd like to answer a call is also very good. To use de with iPhone 5s I can only say that all functions are wonderfully useful. Buy!
