HOW IT WORKS

The WS ALERT X+ combines passive hearing protection with integrated communication technology to reduce noise exposure while maintaining connectivity. The sealed ear cups and internal attenuation system help limit harmful noise, while built-in microphones allow controlled ambient sound to be heard when required.

Bluetooth connectivity enables hands-free calls and audio streaming through connected devices. The noise-cancelling boom microphone filters surrounding noise to support clear communication in loud environments.

The headset also connects to a mobile app, allowing users to adjust settings, monitor performance, and maintain the device through updates.
