Allen 4149 Bionic Electronic Earmuffs 22dB NRR Yellow Safety

The Allen 4149 Bionic Electronic Earmuffs deliver advanced hearing protection with amplified ambient sound awareness for shooters who demand both safety and situational awareness. These electronic earmuffs automatically compress harmful noise while amplifying safe environmental sounds, making them essential for range training and hunting applications.

What Makes This Different

Unlike passive ear protection that blocks all sound equally, the Allen 4149 Bionic earmuffs feature electronic sound compression technology that instantly reacts to loud noises above 82dB. The dual microphone system provides stereo sound amplification up to four times normal hearing levels, allowing users to hear range commands, approaching game, or conversations clearly. The 0.5 millisecond reaction time ensures immediate protection from gunshot noise while maintaining audio clarity for extended wear.

Key Features

• 22dB Noise Reduction Rating (NRR) meets ANSI S3.19 standards for firearms use
• Electronic sound compression activates automatically at 82dB threshold
• Dual stereo microphones amplify ambient sounds up to 4x normal levels
• High-visibility yellow color enhances safety visibility on ranges
• Padded headband and ear cups provide comfortable extended wear
• Compact folding design for easy transport and storage
• 3.5mm auxiliary input jack for audio device connectivity

The electronic circuitry responds within half a millisecond to compress dangerous noise levels while continuously monitoring ambient sound levels. Range officers can communicate effectively with shooters wearing these earmuffs, and hunters maintain awareness of their surroundings without compromising hearing protection. The moisture-resistant construction withstands outdoor conditions, while the battery-efficient design provides extended operational time.
