The Impact Sport BOLT Digital Electronic Earmuff combines five times the sound amplification, a 22-decibel noise reduction rating and a comfortable ergonomic design with easy one-knob control. Power to the speakers inside the earcups automatically shuts off when sound above 82 dB enters the external microphones, attenuating impulse noise with a 0.5-millisecond attack time. Available in black, gray or orange, the earmuff features a four-hour auto shutoff. Batteries are included.
