I was very happy with it at first however after some use, Im not nearly as happy. When it drops out it causes performance issues with my games and software, even crashing them about 50% of the time. I expect more from Jabra. Good product received in good time. Front slide, instep strap and heel strap with adjustable hook and loop closures. I seriously doubt I heard much detail difference. It lights up blue when the station is currently charging items. Seems kind of long considering that is how many hours of music you will have at 80% volume. Hierbei Handelt es sich um einen Lautstärkeregler mit Mute Funktion. Id rather the device doesnt adjust the audio at all.
