They are headsets for the star com intercom, it was the first time I'd actually used it in anger, covering 1200 miles with both passengers and using the radio to communicate with other cars. Using boom bikes communication between me and the passenger was crystal clear up till about 130kph then it sometimes got a bit confused and the VOX cut in when nobody was talking a few times.
Great bit of kit though.
I'm glad i put drain holes in the floor though, else i'd be bailing out
