3M Peltor Optime III Ear Defenders Adults Protective Earmuffs with Headband, Hearing Protection Against High Noise Levels in Industrial Settings, 35 dB, Black/Red

Optime III are high-performance ear defenders designed for industrial and professional use in extremely noisy environments. They feature a double casing to minimise resonance, providing maximum high-frequency muffling while preserving speech intelligibility. An acoustic connection between the inner and outer volumes enhances low-frequency muffling, and broad foam-filled sealing rings offer a comfortable, low-pressure fit for extended wear. The product is available in multiple configurations, including headband, neckband, helmet-attached, and Hi-Viz green variants, with replaceable cushions and hygiene kits. Protection is specified to EN 352 standards, with evidence of strong noise reduction characteristics (SNR around 35 dB) and emphasis on safety in settings such as airports, power stations, marine engine rooms, and print works. All variants are designed to minimize heat and moisture build-up through large cup interiors and cushioning while maintaining good acoustic performance.”
