The 3M Peltor Optime II earmuffs have been specifically designed for environments with high noise levels and effectively dampen sound even at extremely low frequencies. The green cups have a noise reduction rating of SNR = 30 dB. Thanks to the slim design of the shells, Optime II provides exceptional wearing comfort. This minimizes heat buildup and sweating, offering a pleasant wearing experience even during prolonged use. Optimal heat dissipation is ensured by additional ventilation channels in the sealing ring channels. The soft, wide sealing rings are filled with a unique liquid-foam combination, providing particularly low pressure for optimal sealing. The flat headband and the two-point suspension made of stainless steel result in very low pressure on the head. The band is adjustable and adapts perfectly to all head shapes due to its ergonomic design. The 3M Peltor Optime II is used in areas with high noise exposure, such as heavy industry, cement production, construction, airports, textile production, printing industry, and agriculture. A suitable hygiene kit ensures hygienic and economical use of the hearing protection.
