Headband option. The 3M Peltor Optime III ear muffs have been developed for use in extremely high noise nvironments, particularly those dominated by low frequency sounds. The protection is based on a technology with a double casing minimising resonance in the holder casing resulting in maximum high-frequency attenuation. An coustic connection between the inner volume and the volume between the casings in its turn provides maximum low- requency attenuation. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. The 3M Peltor Optime III ear muff stands for effective protection and highest comfort for the wearer.
