3M Peltor Optime III Helmet Attached Earmuff

These earmuffs are ideal for use in extremely loud environments in applications where hard hats are required. Multiple adaptor options are available for compatibility with a wide selection of helmets.

They can reduce noise levels up to 30 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.

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.
