Get comfortable, high performance hearing protection with these 3M™ PELTOR™ Optime™ III Earmuffs. Tested in accordance with EN 352:2020, these earmuffs reduce noise levels up to 34 dB. They are ideal for use in extremely loud environments such as airports, power stations, marine engine rooms and print works. Created with a double-casing technology that minimises resonance in the holder casing that results in maximum high-frequency attenuation. The large space inside the cups helps reduce heat and moisture build-up, and the soft, wide foam cushions offer low contact pressure around the ears, making them comfortable to wear for long periods and increasing compliance through user wear preference.
