3M H540B Peltor Neckband Earmuffs Optime III Ear Muff Hearing Protection Neck Band Class 5

The 3M™ PELTOR™ Optime™ III Earmuffs, H540B are high-performance hearing protectors, developed for use in extremely noisy environments like airports, marine engine rooms, power stations, and print works. Our earmuffs reduce noise levels up to 34 dB and have a double-casing technology that minimises resonance in the holder casing resulting 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. Our earmuff stands for effective protection and the highest comfort for the wearer. The cushions and foam inserts are available as Hygiene Kits which are easy to replace if they become worn or damaged, extending the life of the product. 3M™ PELTOR™ Optime™ III Earmuffs are available in headband, helmet attached and Hi-Viz green models.
