The Allen Company ULTRX™ Bionic Fuse Bluetooth® Earbuds (Model AL4111) provide active electronic hearing protection designed for shooting sports and field use. Certified to ANSI S3.19 with a Noise Reduction Rating (NRR) of 26 dB, the earbuds feature dual directional microphones that compress impulse noises exceeding 82 dB in 0.001 ms (1 ms). Built-in Bluetooth 5.3 allows wireless device connectivity up to a 10-metre line-of-sight range, while three acoustic modes manage ambient sound amplification. The low-profile in-ear design prevents cheek-weld interference against rifle and shotgun stocks, and an IPX5 water-resistance rating protects the internal components against low-pressure water streams and rain. The internal lithium-ion cells recharge via the included hard-shell USB-C charging case.

Key Features

• Active Sound Compression: Dual directional microphones react in 0.001 ms to suppress loud impulses exceeding 82 dB while maintaining situational awareness through 3 ambient acoustic modes.
• Low-Profile In-Ear Design: Eliminates stock interference during cheek weld on rifles and shotguns, unlike standard over-ear muffs.
• Bluetooth 5.3 Connectivity: Connects to smart devices for wireless audio streaming and communications up to 10 metres away.
• Weather-Resistant Housing: IPX5-rated construction protects the earbuds against rain and low-pressure water spray.
• Rechargeable Storage Case: Hard-shell carry case charges the internal lithium-ion batteries via low-voltage USB-C (5V DC) and includes an auto-shutoff feature to conserve power.

Who is the Allen Ultrx Bionic Fuse Bluetooth Ear Buds + Charging Case for?

• Rifle and Shotgun Hunters — Low-profile in-ear form factor provides ANSI S3.19 NRR 26 dB hearing protection without interfering with stock cheek weld, while IPX5 water resistance protects these electronic shooting ear buds from rain in the field.
• Outdoor Sport Shooters — Sound response time of 0.001 ms actively compresses gunfire exceeding 82 dB, while Bluetooth 5.3 enables wireless audio streaming across an operating range of up to 10 metres.
• Range Officers — Dual directional microphones and 3 ambient acoustic modes amplify range commands while maintaining automatic 0.001 ms sound compression to suppress intermittent firearm discharge.

Less suitable for: Sustained heavy indoor range shooting or high-volume magnum calibres exceeding 160 dB peak; these environments are better suited to high-NRR over-ear passive muffs or dual-layer hearing protection systems combining passive plugs with electronic over-ear muffs.
