There is unfortunately very little, sports headphones with which you can make phone calls ... Therefore, I am quickly met with Jabra and signed up for these corded decided (there are still the same as a wireless variant) to listen to music bike without the typical wireless dropouts to and make calls. The headset makes a very solid and well thought-impression (good processing, short cable + extension, good usability ...) With the right silicone essays it also sits perfectly safe on / in the ear, even the jacket collar, it has not crazy, this pleasant and easy to carry. Only the sound could not convince me. But I have fair to say the very linear hence the sound, so instead Driven no distortions clear and clean. For phone absolutely top! But Jabra comes just not from the music and therefore it is thin in the depths and lacks a real bass. Not for booming Gewummer but for a balanced, power / powerful sound. Even with a good equalizer app is no longer much extract - where other simple headphones start Unfold your possibilities, the Jabra begins to übertsteuern and to be unclean (even at moderate load) and so will be a kick bass clicking Bass. Too bad for me he goes back, therefore, because my priority is a beautiful Msikklang.
