The unit includes a Li‑Ion battery, cable and microphone tape and is available in a high‑visibility yellow finish. Maximum radio range is up to 2 km and the product provides up to 20 hours of operating time.

Advantages

The headset offers 31 dB noise attenuation with active level‑dependent ambient listening so users can hear important sounds while remaining protected from hazardous noise.
