So for the price are the real top Bluetooth Headset ... The connect mit'n phone is fast and without any problems. In the sound quality I was skeptical at first, but the sound is really lonely peak. Beautifully clear and the bass is also super low ... The range goes for about 6 meters and fully in order. The battery lasts for 4.5 hours at passable continuous use, -what actually really is not bad for such a small "battery-chen" in the headset ...
