With 3M™ PELTOR™ Optime™ II Earmuffs you get effective hearing protection that also protects against extremely low frequencies. Our earmuffs reduce noise levels up to 31 dB and are tested in accordance with EN 352:2020. They are ideal for use in noisy, demanding environments with significant industrial noise, such as airports, construction sites and agricultural work. Designed for comfort, the spacious cups help reduce moisture and heat build-up, while the soft, wide sealing rings help reduce pressure around the ears. The sealing rings have ventilation channels and are covered in a soft, patterned, hygienic foam, making them comfortable to wear for longer periods of time. The cushions and sealing rings, available as a hygiene kit, are easy to replace if they become worn or damaged, extending the life of the product.
