This product is not a formal connection Xbox / Microsoft, but I do not think it changes anything, given the simplicity of the device. This small device is needed to enjoy the sound through headphones while you party on an Xbox 360. It plugs into the back of the console, next to HDMI. The sound is of very good quality, sizzling (being taken directly from the console) and micro function also works very well. After that it is no miracle, if you have a poor quality headphones, the sound can not be on top. We can nevertheless regrettable that this is not a connector provided in the basic package of the console.
