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 attach securely to various FAST helmet models using a hanging buckle system. 3. After installation, the earmuffs from Comtac communication headsets detach from the original headband and clip directly onto the buckles, which can be fixed into the side grooves of the helmet. Once mounted, the earmuffs offer 360-degree rotation for optimal positioning. Usage: 1. Remove the earmuffs from the original bracket on both sides. 2. Pull the headphone wire out from under the cover, releasing it from the retaining loop. 3. Attach the earmuffs to the hanging buckles provided, aligning and clipping them securely on both left and right sides. 4. Mount 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 it in place using adhesive tape.
