MH 1 Headset.
Offers all the features of the UM1 with the added advantage of a pair of full shell clear custom fit earpieces made from our soft vinyl material. Because the earpieces have a low profile, they slip easily under most helmets. The headset comes with a 50 inch black cable, hard wired toward the bottom of the ear, and a 3.5 mm stereo plug. They offer greatly improved noise suppression over the UM1, and increased levels of comfort over longer periods of use.
