3M PELTOR Optime 105 Earmuffs are intended for noise levels up to 105 dBA. They feature added mass and volume, plus a double shell ear cup design (two cups connected via foam inner layer) to boost the noise reduction through 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 ear cup pivot points that tilt to maximize wearer comfort. Soft, liquid, and foam filled earmuffs fit comfortably against the head to provide an effective noise blocking seal.
