The Allen ULTRX Bionic Electronic Earmuff gives you the best of both worlds: it boosts quiet sounds like conversation and range commands while clamping down hard on the crack of a rifle or the pop of a pistol. Two hi-gain stereo microphones pick up ambient noise around you, and the built-in sound compression cuts off amplification the instant a loud report hits, so you keep your situational awareness without the wince that comes with straight passive muffs.
The electronics run on a dynamic wave compression system paired with symmetrical microphone response, which keeps voices and footsteps sounding natural instead of tinny. The mics are tuned to react in a hurry, dropping out at roughly 82 dB in about 0.02 seconds, so gunfire and other sharp noises get shut down before they reach your ears. When the batteries are off, you still get a certified NRR of 22 dB from the passive muff design, and the whole thing is ANSI S3.19 tested so you know the rating is legit.
An extra-padded headband and plush pillow-foam ear cups make these easy to wear through a long range session or a full day on a loud job site. The rubberized exterior holds up to knocks and drops, and the over-the-head fit adjusts to dial in the seal. Power comes from two AAA batteries (not included), which keeps the muff light and easy to top off with cells you can grab anywhere.
There's a 3.5mm aux port built in, so you can run audio from a phone or radio straight into the muff while you work or wait between strings. Between the amplified hearing, the fast-acting compression, and the comfortable build, the Bionic muff is a solid pick for range days, hunting stands, mowing the yard, or anywhere the noise gets serious.
No, the muffs run on two AAA batteries that you'll need to supply yourself. That's an easy trade since AAAs are cheap and available just about anywhere, so you can keep spares in your range bag. The muff still delivers its full NRR 22 dB passive protection even when the electronics are switched off.
Two hi-gain microphones amplify quieter sounds like conversation and range commands so you keep your awareness. When a loud noise like a gunshot hits, the sound compression cuts the amplification off in about 0.02 seconds at roughly 82 dB. You hear what's going on around you without the ringing that comes from the report itself.
Yes, there's a 3.5mm aux port built into the earmuff. You can plug in a phone, MP3 player, or radio and run that audio straight through the muff. It's handy for downtime at the range or for tuning things out on a long job.
An NRR of 22 dB is a solid rating for most range and hunting use and puts these right in line with popular electronic muffs. For indoor ranges or heavy-caliber sessions, a lot of folks double up with a set of foam plugs underneath for extra margin. Outdoors and with typical rifle and pistol work, the 22 dB rating handles the job well.
