The 3M Peltor Optime III earmuffs have been specifically designed for high noise exposure, combining effective protection with maximum comfort. The black cups have an attenuation rating of SNR = 34 dB. The high 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 inner cup space and the area between the shells also achieves optimal attenuation of low frequencies. The soft, wide sealing rings made of foam ensure a perfect fit. The generous space under the cups minimizes heat build-up and sweating, providing a comfortable wearing experience. A two-point suspension made of stainless steel ensures a consistently low clamping pressure even during prolonged use. The headband is adjustable and adapts perfectly to any head shape thanks to its ergonomic design. The 3M Peltor Optime III is suitable for use in airports, cement production, ship engine rooms, mining, and power plants. Compatible hygiene kits ensure a hygienic and economical use of the earmuffs.
