3M Peltor Optime 105 over-the-head earmuffs feature double-shell technology to provide effective hearing protection.

The 3M™ Peltor™ Optime™ 105 Over-the-Head Earmuff has been developed for effective hearing protection in the most demanding noise environments where noise exposures are expected to reach as high as 105 dBA. The Optime™ 105 over-the-head earmuff features added mass and volume, plus a unique “double-shell” earcup design (two cups connected via foam inner layer) to boost the noise reduction throughout the full range of low and high frequencies. The durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit. The lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort. Soft, liquid &foam filled cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal. *The Noise Reduction Rating (NRR) may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
