Allen ULTRX Bionic Features The Allen ULTRX Bionic Electronic Earmuff is ANSI S3.19 tested and certified delivering a Noise Reduction Rating of 22 decibels to safeguard hearing across a range of noisy environments from the range to the field. Two hi-gain stereo microphones amplify ambient sound for better situational awareness while shooting or working and they automatically shut down within 0.02 seconds once ambient noise reaches 82 decibels protecting the ear from gunshot-level sound spikes. A dynamic wave compression system paired with symmetrical microphone response delivers crystal-clear sound reproduction described by the manufacturer as comparable to a high-definition studio-grade audio system through its Studio Harmonics technology. These features combine to give the wearer both protection and genuinely useful sound amplification rather than a simple pass-through system. Built with an extra-padded headband and soft ear cups the ULTRX earmuff is designed for comfort during extended wear at the range or in the field while a rubberized exterior adds strength and durability for long-term use. An auxiliary port allows the wearer to connect external devices for a personalized audio experience alongside the earmuff s built-in amplification. Power comes from two AAA batteries which are not included but provide extended battery life once installed.
