Howard Leight R02532 Impact Sport 22dB Gray Black Headband Small Ear Protection

It carries a Noise Reduction Rating NRR of 22 in both on and off mode. When the electronic ear protection is switched on it employs builtin directional microphones that amplify ambient sounds to a safe 82 dB. This allows you to hear important commands on the range and crucial environment sounds when hunting. For additional shooting hearing protection it also actively listens and automatically shuts off amplification when loud impulsive sounds like firearm discharges reach 82 dB. Patented Air Flow Control technology allows for a slim earcup design that ensures your firearm stock has clearance while shooting. The padded headband features telescopic height adjustment for a comfortable customized fit. An external audio jack lets you connect the shooting earmuff to an MP3 player scanner or other audio source. The battery delivers approximately 350 hours of usage and the automatic shutoff feature engages after 4 hours to help save battery life. All Howard Leight electronic earmuffs and safety eyewear are compatible for use with each other.
