First, the marriage was slipped (the code from the software was not valid). I had to go and deal with it. People who write that the ears crack partly are right, since the headphones are completely made of plastic (but it depends on the owner and how they are cared for). The microphone may initially be quiet for some people, but this is fixable and, again, whether it is of high quality or not depends on the user, whether he likes it or not (I personally like it, amplified by 10 dB and sound like an inexpensive desktop microphone).
