SonicShieldX (SSX) Technology AXIL's proprietary filter-on-microphone system blocks high-decibel impact sounds at the source while enhancing natural voices and ambient sound with lifelike clarity. The most advanced hear-through system we've ever engineered. Most Natural Hear-Through Sound Ever Built Meticulously tuned dynamic drivers and AXIL's signature hear-through processing deliver the most realistic reproduction of your environment in any AXIL product. Voices, movement, and ambient cues sound exactly as they should. 6A- Hearing Enhancement Amplifies safe sounds up to 6 times, giving you full situational awareness without removing your protection. Hear commands at the range, conversation in the field, and hazards on the job - all with the protection still in.
