3M PELTOR Optime III earmuffs are high-performance hearing protectors for the noisiest environments, e.g. airports, ship engine rooms, power plants and printing works. The double shell minimises resonance in the cups; the large inner space limits heat and moisture build-up. Soft, wide rings reduce pressure and add comfort, and the cushions are easy to remove and refit for cleaning. Maximum attenuation of high and – thanks to a special acoustic link – low frequencies. P3E attachment for fitting to a helmet. Attenuation: 34 dB.
