Allen ULTRX Bionic Fuse Ion Features The Allen ULTRX Bionic Fuse Ion uses hi-gain microphones paired with sound compression circuitry to amplify quiet ambient sound while instantly clamping down on harmful gunshot level noise. That combination lets a shooter hear range commands and conversation clearly between shots without exposing their ears to dangerous spikes in volume. Tested and certified to ANSI S3.19 standards the earmuff carries a 22dB Noise Reduction Rating giving a reliable independently verified level of hearing protection. Bluetooth 5.3 connectivity allows wearers to stream music or take phone calls hands-free while wearing the muffs adding convenience beyond basic hearing protection. A durable comfortable headband is designed for long-lasting wear holding up through repeated sessions at the range or on the job site. Foam-padded ear cups and a symmetrical microphone response work together to keep communication crystal clear whether in the field or indoors. Two AAA batteries power the unit offering up to 34 hours of runtime between changes though batteries are not included in the box. Finished in a slate gray color the ULTRX Bionic Fuse Ion is available for sale at GrabAGun for shooters wanting premium sound comfort and hearing safety in one package.
