Ergonomic hearing protection for the modern workplace. The K1C earmuffs deliver a noise reduction rating of 22 decibels, as well as slot-adapted attachment points for the safety helmet. Outstanding comfort and a pressure-free fit are felt through its use of lightweight materials, bringing together compact and extra-soft cushioned earpieces. Thanks to their soft surfaces, the earmuffs easily mold to your head and are comfortable to wear, keeping your hearing protection on your ears – and your hearing intact. When not needed, earmuffs are able to twist and nest evenly across the top sides of the helmet, so you experience less strain and more balance.
