The 3M MT33-05R Boom Microphone is compatible with ComTac and SwatTac headsets. Replace a lost or damaged boom mic for far less than replacing the entire headset.
This new, redesigned model is water tight (IP68) up to 3 meters, and features a dynamic noise-cancelling microphone. The mic performs better in the wind, and speech remains clearer. The flexible boom design allows for easy positioning. Two pin nexus plug.
This MT33-05R mic has replaced the older MT31 model.
