The previous reviews is hardly anything to add. I have no problems with noise, although much are electronics and a router in the near vicinity, however, the range of the headset can thus be limited. the excellent sound qualities were indeed already described in the other reviews, can only agree with that. crystal-clear surround sound simply, the chat adjustment works well.
The only criticism is really the packaging, took me a long time to get them on. severe injury Duch sharp plastic inclusive. My tip: a paper knife or box cutter, then cut once außenrum (so I've managed it in the end very fix).
