The whole electronics package is integrated into the helmet as well as the plug connecting to the radio. For circuit use, wiring connections are available separately to connect to the most common car radio systems. The plug is on the left hand side of the helmetAdjustable Microphone: Magnetic-dynamic noise-cancelling microphone. Supplied with spacers to move the microphone position closer to the drivers mouthEarmuffs: Certified for track use as they offer excellent isolation from external noises.
