Where do I plug in the XBox Live communicator headset?
The communicator headset is plugged into a standard XBox controller which is then plugged into one of the open controller ports on the XBox. Rumours abounded back in 2004 about a “special SB controller” which had a headset port on it, but this design was never sent into production. This makes sense because none of the XBox Live Friends List management controls can be accessed via a Steel Battalion controller.
