3M Peltor Optime III Neckband Black H540B

Optime III is a super-muff and has been developed for use in extremely noisy environments. The protection is based on a technology with a double casing that minimises resonance in the holder casing. This results in maximum high-frequency muffling, while at the same time it is still easy to understand speech and signals. An acoustic connection between the inner volume and the volume between the casings in turn provides maximum low-frequency muffling. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure, giving effective protection and best comfort. The Optime III conforms to: SNR 35dB, H 40dB, M 32dB, L 23dB.
