Features: 1. The updated accessories are compatible with specialized headphones for a full range of FAST helmets, MICH helmets, and Peltor ComTac radios. 2. Tested compatibility shows that ComTac I and ComTac II headphones can be securely attached to FAST helmets using the included hanging buckle. 3. After installation, the ComTac radio earmuffs detach from the curved headband and clip directly onto the buckle, which fits into the 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. Pull the headphone wire out from the cover (break the retaining loop). 3. Attach the earmuffs to the hanging buckle provided (align properly and secure on both left and right sides). 4. Install the assembly onto the helmet. 5. Route the headphone wire along the top of the helmet and secure it with adhesive tape. Includes: 1 Pair x Headset Holder
