The Allen Company ULTRX Stereo Electronic Earmuff (Model AL4113) in Olive provides reliable active hearing protection for shooters and hunters. Engineered to balance high-level noise suppression with situational awareness, these over-the-head earmuffs feature a certified Noise Reduction Rating (NRR) of 24dB, tested to ANSI S3.19 and CE EN 352-2 standards. By combining dual stereo microphones with automatic sound compression, this headset allows users to hear low-level ambient sounds clearly while instantly suppressing harmful noises above 82dB.

Key Features:

• Stereo Sound Amplification: Built-in dual stereo microphones capture and amplify low-frequency ambient sounds, such as range commands, conversations, and environmental audio, ensuring clear communication.
• Automatic Sound Compression: Features an automatic shut-off mechanism that instantly compresses audio transmission when ambient noise levels reach or exceed 82dB, protecting your hearing from gunfire or industrial noise.
• Compact Foldable Design: The collapsible, folding headband allows the earmuffs to fold down into a compact size, making them easy to pack into range bags, backpacks, or storage compartments.
• Independent Battery Operation: Powered by two standard AAA batteries (not included), eliminating the need for charging cables, external power adapters, or 240V Australian mains compatibility.
• Durable Construction: Built with high-quality ABS plastic to withstand rugged outdoor environments and frequent use in the field.

Who It's For:

The Allen ULTRX AL4113 is designed for Australian sport shooters, recreational hunters, and range officers who require dependable hearing protection without losing situational awareness. While commercial workplaces in Australia often require specific Class ratings under the AS/NZS 1270 standard, the 24dB NRR rating of the ULTRX earmuffs offers excellent, industry-standard protection for recreational shooting sports, hunting trips, and outdoor range use. It is also an ideal choice for DIY enthusiasts, construction workers, and operators in high-noise environments where hearing protection and clear verbal communication are equally critical. Because the unit operates entirely on standard AAA batteries, it requires no mains power or charging infrastructure, making it highly practical for remote Australian hunting locations and off-grid use.
