The Howard Leight Impact Sport Electronic Earmuffs amplify ambient sounds to a safe 82 dB and have an automatic noise-blocking feature for sounds over 82 dB.
They include directional microphones for sound orientation and an AUX input for audio devices, with a 1/8" stereo plug patch cable.
Designed for comfort and convenience, the earmuffs have a low-profile with angled ear cups for firearm clearance and an auto shut-off after 4 hours to save battery life.
