Hi there. With HDMI from your Xbox, you can hook-up the TurtleBeach headset audio input to the audio output of your television, if it has that feature. Otherwise, your best bet would be to obtain an Xbox 360 Audio Adapter Cable (now discontinued). TurtleBeach
has an article about using their headsets with HDMI:
