The 3M Peltor Optime III earmuffs have been specifically designed for high noise exposure, combining effective protection with maximum comfort. The P3E helmet-mounted earmuff features a plug-in attachment for helmets with a 30 mm slot and comes with black cups. It is compatible with all Peltor helmets except for the G2000. The earmuffs have an attenuation rating of SNR = 34 dB. The high safety of the Optime III is based on innovative double-shell technology, which minimizes resonance inside the cup and provides maximum attenuation of high frequencies. The advantage: conversations and warning signals remain clearly audible. An acoustic connection between the inner cup space and the area between the shells also achieves optimal attenuation of low frequencies. For a perfect fit, the soft, wide sealing rings made of foam ensure comfort. The generous space under the cups minimizes heat buildup and sweat formation, providing a comfortable wearing experience.
