The 3M Peltor Optime III earmuff has been specifically designed for high noise exposure, combining effective protection with maximum comfort. The model H540P3EV features a plug-in attachment for helmets with a 30 mm slot and is compatible with all Peltor helmets except for the G2000. The earmuff has an attenuation value of SNR = 35 dB and ensures high visibility thanks to its Hi Viz design in bright green. The unique safety of the Optime III is based on innovative dual-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 interior of the cup and the space between the shells also achieves optimal attenuation of low frequencies. The soft, wide sealing rings made of foam ensure a perfect fit, while the generous space under the cups offers additional comfort.
