3M™ Optime 105 Behind-the-Head Earmuffs H10B 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 headband is allows for easy wear with hard hats, and soft, liquid and foam filled earmuffs fit comfortably against the head to provide an effective noise-blocking seal.
