Developed for effective hearing protection in the most demanding noise environments where noise exposures are expected to reach as high as 105 dBA. This over-the-head earmuff features added mass & 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 & high frequencies. The durable stainless steel headband resists bending & warping & distributes weight for a low-pressure fit. The lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort. Soft, liquid & foam filled cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal. Material(s): ABS; Ear Cushion Material: Foam; Noise Reduction Rate (NRR): 30 dB; Style: Over-The-Head.
