Allen Bionic Fuse Features The Allen Bionic Fuse earns an ANSI S3.19 tested NRR of 22 dB giving reliable protection across loud range and field environments. Its four hi-gain omni directional microphones amplify ambient sound so users stay aware of their surroundings then automatically mute within 0.02 seconds once sound exceeds 82dB shielding hearing from sudden gunfire or machinery noise. Studio Harmonics technology processes incoming audio for clarity comparable to a studio-grade system while a dynamic wave compression system and 6x omni-hearing boost sharpen sound detail further. Bluetooth 5.3 connectivity lets the earmuff pair with a phone or radio so wearers can take calls or stream audio without removing hearing protection. Comfort comes from gel-filled ear cups and air-gel cooling technology that keep the muffs from growing hot and uncomfortable during long sessions backed by extra-padded headband that folds flat for storage and transport. A rubberized exterior shell adds durability for rough handling in the field or on a job site. The included 1200mAh USB-C lithium battery delivers up to 34 hours of use on a charge so the earmuff keeps pace through a full day of shooting or work. Shake Awake style power management and Bluetooth streaming make this a practical choice for anyone who needs long-wear hearing protection without sacrificing communication.
