What I am saying is that with the controller in question, any wired headset i use (havent tried a wireless headset and probably wont) leaves the headset on.
IE, we are on a team in Halo 3 and someone has an open mic all the time, whether they are speaking or not. It's not bothersome to me since I can't hear it, but it irks my teammates.
I was hoping someone here may have had a similar problem and figured out how to fix it by doing something to the controller.
another thing, even if I press the mute button on the headset, it still sends white noise through xbox live. and it is only the controller, not the headset. My other controller works just fine with my headsets.
