The 3M™ Peltor Optime III H540A Headband Earmuffs offer high performance hearing protection. They reduce noise levels up to 33dB and use double casing technology to minimise resonance for maximum high-frequency attenuation. Soft, wide cushions help reduce pressure around the ears, while large space inside the ear cups helps minimise heat and moisture build up, so the user stays comfortable and safe for long periods of wear. Developed for use in extremely noisy environments, such as industrial and construction sites, airports, engine rooms, and power stations.
