Description
The Allen ULTRX Bionic Fuse is a neckband-style earbud built for folks who want hearing protection and music from the same set. The buds sit in your ears while a flexible band rests around your neck, which keeps them handy when you pop one out to talk and cuts down on the odds of losing a bud in the grass or gravel.
What the Bionic Fuse Earbuds Bring to the Range
These are electronic ear protection first and headphones second. ANSI S3.19 tested and certified with an NRR of 26dB, they knock down the crack of gunfire while the dual built-in microphones feed you the surrounding sounds you want to hear, like range commands or your buddy's next move. The mics are designed to shut down within a fraction of a second when noise spikes to 82dB, so loud reports get cut off before they reach your ears. Two program settings let you dial the sound to match wherever you are, whether that's a busy indoor range or a quiet stand at dawn.
Bluetooth 5.3 and Everyday Wear
Bluetooth 5.3 keeps the connection to your phone steady with solid range and good battery life, and the voice synthesis tuning helps calls and audio come through clean. That makes the Bionic Fuse just as useful mowing the lawn, running the shop, or on a jog as it is behind a rifle. An IPX5 water resistance rating means sweat and light rain won't be a problem, and the whole thing recharges over USB-C so you're not hunting for a proprietary cable.
Fit and Feel of the ULTRX Bionic Fuse
The compact, ergonomic shape is made to stay put and stay comfortable through a long day, and the neckband design keeps the buds within reach even when they're not in your ears. For anyone who's been juggling a set of muffs and a pair of earbuds separately, this rolls both jobs into one piece of gear that lives around your neck all day.

Frequently Asked Questions
Do the ULTRX Bionic Fuse earbuds work as hearing protection while playing music?
Yes, that's the whole point of this design. They're rated at 26dB NRR and ANSI S3.19 certified, so they protect your ears while you stream audio or take calls over Bluetooth. The dual mics also feed in the sounds around you and clamp down fast when noise spikes to 82dB.
How do the Bionic Fuse earbuds charge?
They use a built-in rechargeable lithium battery that tops off through a standard USB-C cable. There's also an auto shut-off that kicks in after two hours in standby to save battery when you set them down and forget about them.
Are the Allen ULTRX Bionic Fuse earbuds okay to wear in the rain or while sweating?
They carry an IPX5 water resistance rating, which handles sweat, splashes, and light rain without trouble. That makes them a good fit for workouts, yard work, and outdoor range days, though they aren't meant to be submerged.
What's the difference between the neckband version and the case version of the Bionic Fuse?
This model is the around-the-neck neckband style, where the buds connect to a flexible band that rests on your neck so they stay handy when you pop them out. Allen also makes a fully wireless version that comes with a charging case instead of a band. Both share the same core electronic protection and Bluetooth features.
