Due to the good Reznesionen I bought the headset for my xbox 360. So far I had no problems with the Wi-Fi, despite relatively weak link. This wireless headphones but obviously greatly disturbed the WLAN with me. It came more often to complete disconnections. Therefore caution in low-Fi and prefer to buy wired headset. I have the X31 (naturally at a loss) sold and I switched to the X11. Has the same great sound and a aussreichend long cable. In addition, you can still save the cost of the battery and the environment the waste.
