These electronic earmuffs feature Veil Tac Gray camouflage pattern for tactical applications and hunting environments.

What Makes This Different

Unlike passive hearing protection that blocks all sound, the Allen 4147 Bionic system amplifies ambient sounds up to 5 times normal level while instantly cutting harmful noise above 82 decibels. The electronic circuitry responds in 0.02 seconds to protect hearing from sudden loud sounds. Independent volume controls for each ear allow customized hearing enhancement based on environmental conditions and personal preference.
