The EARMOR M31X-Mark3 MilPro is a helmet-mounted electronic shooting earmuff. It uses a sound control system with 5 adjustable sound modes to help with situational awareness and communication in noisy environments. It can be combined with the S10D and S27 to upgrade to communication mode, or disassembled for stand-alone use.
It comes with a replaceable bracket for mounting on a helmet rail, plus a helmet rail mounting kit (M16). The flip-back, 360° rotating structure and modular design also allow an ARC rail to be used as another way to wear it. The earcups rotate to the sides and back of the helmet to follow the contour of the head. An M62 headband accessory is included for other wearing options.
The shell is 3 mm thick modified ABS plastic, molded in one piece. The bracket is ABS mixed with PC. Sealed silicone ear pads fit snugly against the face, block sound leakage and resist sweat. A 3.5mm AUX audio input cable connects media devices. The listing does not include a helmet.
