3M™ PELTOR™ Tactical 6-S Headset, Headband model MT15H67FB-01 provides hearing protection with a Noise Reduction Rating (NRR) of 20 decibels while also allowing 2-way communication for workers to talk without removing the headset. Separate microphone, receiver, amplifier, and volume control in each earcup gives true stereophonic sound. The earmuffs attenuate (soften or reduce) high level noise to help protect hearing. Impulse Noise attenuation immediately softens sudden loud Noises. The earmuffs can be folded into a compact size that is easy to store or transport. Made with a combination of foam, plastic and metal, the headset is lightweight for comfort that allows all-day wear.
