Allen 4109 Bionic Fuse Bluetooth Earmuff 22 dB Midnight Gray

The Allen 4109 Bionic Fuse is a Bluetooth-enabled electronic earmuff finished in Midnight Gray and certified to a 22 dB Noise Reduction Rating under the ANSI S3.19 standard. Part of Allen's ULTRX line, the Bionic Fuse delivers premium hearing protection for shooters who do not want to give up environmental awareness on the range.

An ABS plastic over-the-head frame houses Bluetooth 5.3 wireless audio paired with four hi-gain omni-directional microphones. A dynamic wave compression system with a 6x omni-hearing boost manages impulse noise while still feeding clear low-level ambient sound to the shooter, giving you the best of both worlds on the firing line.

Power comes from an internal 1200 mAh rechargeable lithium battery charged via USB-C, so there is no scrambling for coin cells before a range session. Backed by Allen's blend of comfort and electronics, the 4109 Bionic Fuse is a modern take on over-the-ear hearing protection suitable for rimfire and centerfire use alike.
