Allen ULTRX Bionic Fuse Features The Allen ULTRX Bionic Fuse earmuff is ANSI S3.19 tested and certified to a 22dB Noise Reduction Rating giving dependable protection across a range of noisy environments. Four hi-gain omni directional microphones boost awareness of surrounding sound and automatically shut down within 0.02 seconds once ambient noise reaches 82dB protecting hearing without cutting off situational awareness. Bluetooth 5.3 connectivity lets the wearer pair a phone or radio directly to the earmuff and Studio Harmonics technology is built in to keep that paired audio clear rather than muddy. A symmetrical microphone response keeps communication crisp whether the wearer is on the range or on a job site. An air-gel cooling system and plush pillow foam padding keep the Bionic Fuse comfortable through extended wear while an extra-padded headband folds flat for easy transport. The rechargeable 1200mAh lithium battery runs up to 20 hours on a charge and recharges through the included USB-C cable so there is no disposable battery to replace. A rubberized exterior shell adds durability for long-term use in the field or on a job site. Finished in Cement Gray the Allen ULTRX Bionic Fuse rounds out Allen s hearing protection lineup with a premium electronic option.
