Allen 4159 Ultrax Bionic Electronic Hearing Protection 26dB NRR

The Allen 4159 Ultrax Bionic Electronic Hearing Protection delivers advanced sound amplification technology with 26dB noise reduction rating for shooters who demand crystal-clear communication without compromising ear safety. This electronic earmuff system automatically compresses harmful impulse noise while amplifying ambient sounds below 82dB.

What Makes This Different

Unlike passive hearing protection that blocks all sound, the Ultrax Bionic features dual microphones and digital sound processing that enhance low-level sounds like range commands and conversations while instantly shutting down gunshot noise. The response time measures less than 0.5 milliseconds, providing instantaneous protection from sudden loud noises. Independent volume controls for each ear allow customized hearing enhancement based on individual needs and shooting positions.
