CommEar earpieces channel radio communications directly into your ear - clearly and covertly. Made in the USA from an ultra-soft hypoallergenic material, their ergonomic design makes them comfortable for extended use. Because they fit snugly inside your ear shell, you can use them while wearing a helmet, mask, or hat, or while employing a telephone or headset. CommEar earpieces don't block the ear canal, permitting virtually normal hearing of ambient sounds. Sold in packages of two right ear units. Each individual earpiece is packaged in a convenient carry case.
