Allen ULTRX E-Muff Features The Allen ULTRX E-Muff is ANSI S3.19 tested and certified to deliver an NRR of 23dB providing dependable hearing protection across a range of noisy shooting environments. A single high-frequency microphone amplifies ambient sound letting the wearer hear range commands conversation or approaching game clearly while the muffs stay on. For added protection the microphone automatically shuts down the instant ambient noise reaches 82dB meaning a gunshot is dampened rather than amplified through the speaker. This combination of amplification and automatic cutoff gives shooters the best of both situational awareness and hearing safety in one unit. Powered by a single AAA battery the ULTRX E-Muff delivers up to 300 hours of runtime before a battery change is needed making it reliable for extended range days or hunting trips. The compact foldable design allows the muffs to pack down small for storage in a range bag or glove box between uses. Finished in black the earmuffs have a clean functional look that matches most other range gear. For shooters who want amplified awareness paired with solid passive protection the Allen ULTRX E-Muff is a practical choice.
