Features: 1. The upgraded accessories are compatible with specific headphones for a full range of FAST helmets, MICH helmets, and Peltor Comtac communication devices. 2. Tested compatibility allows Comtac I and Comtac II headphones to be attached to various FAST helmets using a clip-on buckle system. 3. After installation, the earmuffs from Comtac communication headsets detach from the original headband and securely attach to the buckles, which fit into grooves on both sides of the helmet. Once mounted, the earmuffs can rotate freely. Usage: 1. Remove the earmuffs from the original bracket on both sides. 2. Extract the headphone wire from the cover, ensuring the loop is disengaged. 3. Attach the earmuffs to the hanging buckles provided, aligning them properly on the left and right sides. 4. Mount the assembly onto the helmet. 5. Route the headphone wiring along the top of the helmet and secure it with adhesive tape. Package List: 1 Pair x Headset Holder
