Allen Company
The Allen Ultrax 4147 Bionic electronic earmuffs deliver professional-grade hearing protection and situational awareness in a package built for serious shooters and hunters. These active noise-reduction earmuffs combine a 22 dB Noise Reduction Rating with dual hi-gain microphones and dynamic wave compression, so you get real-time hearing enhancement when it matters while staying protected during loud impulses. They're ANSI S3.19 certified, meeting the industry standard for hearing protection devices—a credential that matters when your ears are on the line.
The dual microphones automatically suppress sound at 82 dB within 0.02 seconds, clamping dangerous noise spikes instantly while letting you hear range commands, game movement, and conversation at normal levels. This isn't passive foam-and-cup protection; these are smart earmuffs that work for you. The Veil Tac Grey finish fits tactical and outdoor setups without standing out. An auxiliary port lets you connect external audio devices if you want to integrate comms or playback, adding flexibility for different shooting scenarios.
Comfort matters on long days at the range or in the field. The Ultrax 4147 features extra-padded ear cups and a cushioned headband designed to distribute pressure evenly, so you can wear them for hours without fatigue. The rubberized exterior is tough enough for hard use and built to last through seasons of hunting, competition, or training. Two AAA batteries power the electronics—not included, but readily available anywhere—and they're sized for extended use without constant swaps.
