Features: 1. The updated accessories are compatible with specialized headphones for FAST helmets, MICH helmets, and Peltor Comtac communication systems. 2. Tested compatibility allows Comtac I and Comtac II headphones to be attached to various FAST helmets using a secure buckle connection. 3. The earmuffs from Comtac communication headsets can be detached from the original headband and directly clipped onto the mounting buckle. The buckle secures into the side grooves of the helmet, allowing the earmuffs to rotate freely after installation. Usage: 1. Remove the earmuffs from the original bracket on both sides. 2. Pull the headphone wire out from the cover (break the loop seal as required). 3. Attach the earmuffs to the hanging buckle provided (align properly and secure on both left and right sides). 4. Mount the assembly onto the helmet by inserting the buckle 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
