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.
