When Headset This device is not to be used. The voice coming muffled through the micro, the noise reduction distorted. Others recognize and understand a not correct and annoyed after a short time. When it comes to a complete micro-flop. I use and give 2 stars for the comfort, which is good and where there is nothing to complain the sound from the headphone. Pay me now but rather look for a decent desktop micro, because that's not here right for dieenigen who want to be at least halfway verstannden. Because, my very old desktop micro of Hama, which has sometimes cost me 3 Euro, much better rübergebracht.
