The Allen Ultrax 4109 Bionic Fuse Bluetooth ear muffs bring electronic hearing protection and wireless audio together in one thoughtfully designed package. Whether you're running a long day at the range, hunting, or managing noise on a work site, these medium gray muffs give you genuine NRR 22dB protection while keeping you connected and comfortable. They're built to handle serious sound environments without sacrificing the ability to hear important ambient sounds—or to stream audio and take calls when you need them.
What sets the Bionic Fuse apart is the combination of smart electronics and physical comfort. The four omnidirectional microphones capture surrounding sound with a 6x hearing boost, so you stay aware of what's happening around you. Those microphones automatically shut down within 0.02 seconds if sound hits 82dB, giving your ears an extra layer of impulse protection. Bluetooth 5.3 connectivity lets you pair to your phone or other devices without cords getting in the way, and the 1200mAh lithium battery charges via USB-C for reliable all-day runtime.
Comfort matters during extended wear, and Allen engineered these with soft gel-padded ear cups that run cool and an extra-padded headband that folds flat for transport. The rubberized exterior stands up to field use. They're ANSI S3.19 tested and certified, so you know the protection rating is genuine.
