The Allen ULTRX Bionic Electronic Earmuff (Model AL4108) in Midnight Gray is engineered to deliver high-fidelity environmental hearing alongside reliable, rapid-acting hearing protection. Featuring a Noise Reduction Rating (NRR) of 22 dB, these earmuffs utilize advanced electronic compression to shield your ears from harmful impulse noises while ensuring you remain fully aware of your surroundings. The unit is designed with a folding over-the-head band and plush pillow foam ear cups, providing a secure and comfortable fit during extended use in the field or at the shooting range.

Key Features:

• Studio Harmonics Technology: Delivers high-definition, studio-grade audio clarity, ensuring ambient sounds, conversation, and range commands remain natural and easy to understand.
• Dynamic Wave Compression: Automatically detects and compresses sounds at or above 82 dB with an ultra-fast reaction time of 0.02 seconds, protecting your hearing from immediate impulse noises like gunfire.
• Dual Symmetrical Stereo Microphones: Equipped with two hi-gain microphones that provide accurate directional sound localization, allowing you to identify the exact origin of ambient noises.
• Integrated 3.5mm Aux Port: Features a built-in 3.5mm auxiliary input jack, allowing direct connection to external audio devices, handheld communication radios, or MP3 players.
• Battery-Powered Portability: Runs on two standard AAA batteries, eliminating the need for mains chargers, USB cables, or SAA-certified 240V adapters, which makes it highly practical for remote off-grid use.
• Ergonomic Folding Design: Built with a compact folding headband and soft pillow foam padding on the ear cups to ensure comfort during long hours of wear.

Who It Is For:

The Allen ULTRX Bionic Electronic Earmuff is primarily designed for Australian sports shooters, hunters, and range officers who require situational awareness without compromising on hearing safety. Because it operates on standard AAA batteries, it is highly suited for multi-day hunting trips in remote Australian environments where access to 240V charging infrastructure is unavailable. While its ANSI S3.19 certification is widely accepted and respected by recreational shooters and hunters across Australia, commercial and industrial operators should note that it does not carry the joint AS/NZS 1270:2002 certification often required for official Australian industrial worksites.
