I have the phone now about three months at the gym regularly in use. He does what he should. Is stuck, you can rely on it that you can not constantly the handset must press in the ears or the whole part otherwise slipping. Sitting where he is. In this regard, so full marks. He also does not press or the like. The sound is so far also in order. For perquisites it lines thick. One shortcoming, however, there are: the fact that the listener sits diagonally in the ear, he closes this little, so that both external noise (which can be considerable, especially in the gym so) little shielded, and some of the sound from the handset get lost. Listen almost always at maximum volume. Especially in spoken word (podcasts, etc.) it is fast too quiet. Applies a fortiori to classical music. But otherwise perfect.
