The Gladiator V features a vertical steel headband available in 4 sizes to guarantee proper personal fit (when your team T&Es the headset, you will receive one of each size frame for fitment for each operator). An adjustable rear head strap prevents forward and rearward movement of the headset once positioned properly on the head. Bone conductors, installed inside each sidepiece housing, relay radio RX directly through the face to the inner ear. A waterproof / noise canceling boom microphone is featured and available for order and manufacture on the opposite side (right when worn) for left handed shooters.
