The 3M PELTOR Optime II earmuffs are a highly effective hearing protection solution that dampens even extremely low frequencies. They are ideal for loud, demanding environments with high exposure to industrial noise, such as airports, construction sites, or agricultural work areas. The earmuffs reduce noise levels by up to 31 dB. They feature sealing rings filled with a unique combination of liquid and foam. The generous space inside the cups helps to prevent heat and moisture buildup. The wide, soft cushions reduce pressure around the ears, allowing for comfortable wear even over long periods. The cushions and foam inserts are available in hygiene kits that can be easily replaced when damaged or worn, extending the product's lifespan. Maximum noise level protection: 105 dB.
