I have read some reviews on Amazon and other sites, and have heard only good through the headset. That reminds me of the sound is to mau from my TV and I do not have money or my neighbors no nerves for a plant, I decided me the X31 to buy. Apart from the price advantage I felt it as very positive that we should listen to the chat with the headset better. And I can all the good things that are said about the headset only confirm. The sound is really great and processing solid (apart from the battery cover, which seems somewhat smoothly on and to go to). Especially the microphone like it very much, because of the enormous flexibility. It is easy to press in any position and does not wear this out. I have in my room a wireless router available and so far I had no problems with interference or the like. That the headset is wireless sets on the whole nor the crown. The 83 Euros are invested here wonderful.
