The 3M™ PELTOR™ H540A Optime™ III 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.

• Features 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
• Durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit
• Lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort
• Soft, liquid & foam filled replaceable cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal
• High protection level: SLC80-33db, Class 5
