3M™ PELTOR™ Optime™ III Earmuffs are high-performance hearing protectors designed for use in extremely noisy working environments. They provide noise attenuation up to 33–34 dB (SNR) and are tested and certified to EN 352-1:2020 and EN 352-3:2020 standards.

Featuring double casing technology, these earmuffs minimise resonance within the cup, delivering maximum high-frequency noise attenuation. The large internal cup volume helps reduce heat and moisture build-up, while the soft, wide foam sealing cushions ensure low contact pressure and outstanding comfort during prolonged wear.

Replacement cushions and foam inserts are available as Hygiene Kits, making maintenance easy and extending product lifespan.
