For noise levels up to 95 dBA, the lightweight and comfortable behind-the-head earmuffs feature low-profile earcups that fit well with most helmets, eyewear, and other safety equipment.
– Multi-position designs, available in headband, neckband, helmet-attachable and folding models.
– Stainless steel construction resists bending and warping.
– Earcup pivot points tilt for optimum comfort and efficiency.
– Ultra light with liquid/foam filled earmuff cushions.
– Color-coding for compliance sighting.
– Noise Reduction Rating (NRR)*: 21 dB. CSA Class B
*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.
