HexArmor K-Series Ceros K2M Magnetic Earmuffs
The HexArmor K-Series Ceros K2M Magnetic Earmuffs are helmet-mounted hearing protectors designed to integrate with compatible HexArmor Ceros safety helmets using the Click-and-Go magnetic mounting system. The magnetic interface allows the earmuffs to be quickly attached, removed, and repositioned while providing high-level hearing protection for industrial, construction, utility, work-at-height, and other high-noise environments.

The K2M features memory-foam cushioned earpieces for a comfortable, low-pressure seal during extended wear. The ergonomic design helps distribute weight close to the helmet, while the rotating mounting system allows the earmuffs to move between the operating, standby, and storage positions.
Unlike the K2C slot-mounted earmuffs, the K2M Magnetic is designed specifically for HexArmor's magnetic helmet interface. A compatible HexArmor Click-and-Go Magnetic Helmet Adapter is required and sold separately if the helmet is not already equipped with the magnetic interface.
