SM1P headsets enable communication via two-way radio, Bluetooth® and headset-to-headset, as well as face-to-face, in hazardous, high-noise environments, protecting hearing while keeping the operator aware of what is happening around them.

SENS® technology (Speech Enhancement, Noise Suppression) isolates and enhances speech while reducing harmful background noise.
