I just upgraded to the new Call of Duty Black Ops II Earforce Tango headset from the old PX5. I have not been able to figure out how to get my voice to playback through the headset. My PX5s do and I would have thought that these new ones do too. I looked in the full user guide at turtle beaches website and there was nothing on the subject. If anyone can help me I would apreciate some advice.
