HexArmor K-Series Ceros K2M Mechanical Earmuffs

The HexArmor K-Series Ceros K2M Mechanical Earmuffs are helmet-mounted hearing protectors designed specifically for use with HexArmor’s mechanical face shield system. They provide a Noise Reduction Rating of 25 dB and CSA Class A hearing protection while allowing hearing and face protection to be integrated into a single Ceros helmet system.

The K2M Mechanical Earmuffs feature extra-soft memory-foam ear cushions for a comfortable, low-pressure fit during extended wear. Their ergonomic construction helps improve balance and reduce strain when mounted to the helmet, while 360-degree rotation allows the earmuffs to move between operating, standby, and resting positions.

Unlike the K2C, which mounts directly into helmet slots and is intended for use without a face shield, the K2M Mechanical is specifically designed to work alongside HexArmor’s mechanical face shield. A compatible mechanical face shield with adapter is required and sold separately.
