3M™ Peltor™ Optime 105 Over-the-Head Earmuffs are built with double-shell technology to provide effective hearing protection.


These earmuffs have 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 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.

The durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit.

Up to 105 dBA protection!
