AXIL CRX Earbud Hearing Enhancement & Protection

The CRX isn't just hearing protection - it's the most acoustically refined electronic earbud AXIL® has ever made. Every component was meticulously selected, every driver hand-tuned, and every frequency balanced to produce one goal: the most realistic, natural reproduction of your environment through a hear-through system. Voices sound like voices. Footsteps sound like footsteps. The world around you comes through with clarity that other ear pro simply can't match.

At the heart of the CRX is SonicShieldX™ (SSX) technology - AXIL's proprietary filter-on-microphone system that places an impact filter directly on top of the hear-through microphone. This blocks dangerous high-decibel sounds at the source before they ever reach your ear, while simultaneously allowing safe mid and low-decibel sounds - conversation, commands, ambient environment - to pass through with lifelike clarity.

What sets the CRX apart from every other earbud in its class is the MMCX connector system. Out of the box, the CRX is a standalone electronic hearing protection and enhancement device. But connect the optional CRX LINK Bluetooth Adaptor and it becomes a full wireless audio system.

Built to IP65 standards, the CRX earbuds handle dust, sweat, and rain without hesitation. Tap controls let you toggle hear-through and cycle volume without fumbling. Multiple foam and silicone tip options let you dial in the perfect fit and the right level of protection for every environment. And with 10 hours of run time, the CRX goes as long as your day does.
