This headset consists of a pair of slimline stereo earpieces for mounting inside your helmet via stick on velcro pads (supplied). The headset is terminated with a right angle 3.5mm stereo jack (suitable for most MP3 players etc.). 1 earpiece has a 60cm lead, the other a 40cm lead.
The headset then connects to the inline volume control unit. This has a re-positionable crocodile clip for securing to clothing and a coiled cable on the MP3 side. The total length extends from 55 cm to 100 cm. The volume control unit has a straight 3.5mm stereo socket and right angle 3.5mm stereo jack plug.
This design allows you to quickly unplug the headset from the voume control when removing your helmet, whilst keeping the cables in place and your MP3 player securely stowed in a pocket.
