Provides a protective seal without excess pressure while the pivoting earcup connections maintain the seal and proper alignment. Large earcup openings and soft, foam-filled cushions offer a snug, comfortable fit. Noise Reduction Rating* NRR 20 dB (CSA class B) when the band is worn over-the-head. NRR 22 dB (CSA Class A) when the band is worn under-the-chin. NRR 22 dB (CSA Class B) when band is worn behind-the-head. *The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
