What is the Noise Reduction Rating (NRR) of the Allen ULTRX Slim Profile Earmuffs, and how does the slim profile benefit shooters?

These earmuffs offer a Noise Reduction Rating (NRR) of 23 dB, providing excellent protection against high-decibel gunfire. The ultra-slim profile ear cups are specifically designed to prevent interference with your rifle or shotgun's cheek weld, ensuring comfortable and consistent aiming without obstruction. They are also ANSI S3.19 compliant for safety.

Are these earmuffs suitable for both hunting in the Australian bush and use at an indoor shooting range?

Yes, the Allen ULTRX Slim Profile Earmuffs are ideal for both hunting in the Australian bush and training at shooting ranges. Their 23 dB NRR effectively protects against high-decibel gunfire. For maximum decibel reduction in very loud environments like indoor ranges, they can be comfortably paired with foam earplugs underneath.

Do these Allen ULTRX earmuffs require batteries or any special electrical certification for use in Australia?

No, these are passive earmuffs, meaning they do not require any batteries or external power to function. Consequently, as they contain no electronic components, they are exempt from Australian electrical safety certifications such as the Regulatory Compliance Mark (RCM) or SAA approvals.

How comfortable are these earmuffs for extended wear, and are they easy to transport with other gear?

The Allen ULTRX earmuffs are designed for comfort during prolonged wear, featuring a soft, padded headband and cushioned ear seals to minimize pressure points. Their compact foldable design allows the ear cups to fold inward, making them easy to store and transport efficiently in your range bag or backpack alongside items like the Allen AL44411 Deluxe Lockable Handgun Case.

Passive Hearing Protection - Allen ULTRX AL4153

The Allen ULTRX Slim Profile Passive Earmuff (Grey, Model AL4153) provides reliable, battery-free hearing protection designed for shooters, hunters, and industrial workers. Featuring a Noise Reduction Rating (NRR) of 23 dB, this passive earmuff utilizes high-grade acoustic foam to dampen loud impulse noises without the need for electronic components. Its ultra-slim profile is specifically engineered to prevent the ear cups from bumping against a rifle or shotgun stock, allowing for an uninterrupted cheek weld when aiming. Because it is a passive design, it requires no batteries or external power, making it a maintenance-free addition to your shooting gear that is fully exempt from Australian electrical safety certifications like the RCM or SAA.

Ultra-Slim Profile: Low-bulk ear cup geometry minimizes weight and prevents interference with firearm stocks during aiming.

Who It Is For:
