Peltor Tactical 6S Hearing Protectors block out harmful noise while amplifying low-level sounds. You get the best of both words. AOSafety Peltor Tactical Hearing Protectors protect your ears from dangerous impulse noise like gunfire while also giving you distortion-free amplification of low level sounds like range commands and conversation.
