Hello Digitec I would be happy if you could answer three questions for me: 1. do I need other accessories (controller adapters) for the headset to work on an Xbox one? 2. does the supplied USB control box with sound card work on an Xbox one? 3. if the answer to question two is no, will 7.1 sound work at all? I'm asking these questions because I can't get a colleague's test headset to work on the Xbox. I look forward to your answer, greetings Ghosti.
