Ergonomic hearing protection for the modern workplace. The K2C earmuffs deliver a noise reduction rating of 25 decibels and 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.
