Features: 1. The updated accessories are compatible with specialized headphones for FAST helmets, MICH helmets, and Peltor Comtac radio systems. 2. Tested compatibility allows Comtac I and Comtac II headphones to be attached to a full range of FAST helmets using a clip-on buckle system. 3. The earmuffs from Comtac radio headphones can be detached from the original headband and directly attached to the mounting buckle. The buckle secures into the side grooves of the helmet. Once installed, the earmuffs can rotate freely. Usage: 1. Remove the earmuffs from the original bracket on both sides. 2. Pull the headphone wire out from the cover (break the retaining loop if present). 3. Attach the earmuffs to the mounting buckles (align properly and secure on both left and right sides). 4. Install the assembly onto the helmet by securing the buckles into the side grooves. 5. Route the headphone wiring over the top of the helmet and secure with adhesive tape. Includes: 1 Pair x Headset Holder
