The low mass, Noise-cancelling Microphone, mounted on the flexible boom arm, is an electret type.
The headstrap is made of soft nylon material with vulcro fasteners to enable wearing around the fore-head and fasten the headset to the side of the helmet. Headset is designed to be worn over the left ear to avoid interference with shoulder-fired weapons for most users. Low profile of the headset housing and the earphone allows the user to wear even the most close fitting ballistic infantry helmet or other specialized headgear, such as ski-troop parka hoods, paratroop helmets or natural head-dress. The headset is easily hidden under the helmet and when not being worn, it is reasonably compact to be coiled up and carried in a jacket or trouser pocket.
