One, I think, more important point was but so far hardly addressed:
In order to tap the sound you have to use either the original XBox360 Adapter HDMI, or AUX OUT have on TV. There are various connection options but also enough videos on the net, also show the low-cost craft solutions.
The headset or the enclosed components are processed very valuable and make a good impression. The instalation was, done in a few minutes thanks to the comprehensive videos on the net. Despite wireless router, wireless telephone, cell phone and baby monitor in the room I could find no faults. The "Mic Monitoring" function I would inscribedable as something used to, as you now "normal" while listening to your own voice in the headphones. This results in a certain Hall, with which one listens to himself talk. After about 2 hours online, I had gotten used to it and no longer find it annoying. The microphone as well as the entire headset is very well adapted in all areas.
The settings for both the game sound and the voice are very good.
The game sound, just as it now perceive with the X31, I've never seen so detalliert.
All in all you get with the X31 a great Wireless Gaming Headset for XBox360 with excellent price / performance ratio.
