I came Headset now about 6 months. Sound quality is very good and the quality of the microphone as well. Nevertheless, the microphone has the great defect in a 2-3 months long cycle give up the ghost. It is the 3rd time I Nowe happens within 6 months that the microphone is only strange noises in the other conversation partners and after a few minutes then no longer goes. I still do not know what is the actual error, but with this great deficiency, I would recommend to not unfortunately.
