Lightweight, electronic ear muffs automatically reduce harmful noise above 85 decibels to protect your hearing from gunfire, but amplify low level sounds to help you hear voice commands. Four, independent, high frequency directional microphones accurately detect even the faintest noise. Dual, individual volume controls and amplifier circuits provide stereo sound; built-in automatic shutoff circuit extends battery life.
