3M PELTOR LiteCom Plus Wireless Ear Defender 31dB Yellow Noise Cancelling

The 3M PELTOR LiteCom Plus Wireless Ear Defender (MT73H7P3E4410EU) is a helmet-mountable communication headset designed for noisy work environments. It combines hearing protection with an integrated pre‑programmed analog 2‑way radio, a noise‑cancelling microphone and a level‑dependent ambient listening function to help maintain situational awareness while working. 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. An IP68‑rated microphone ensures dust and water resistance, and the noise‑cancelling microphone plus VOX functionality support clear voice communication in loud conditions. The rechargeable Li‑Ion battery provides long operating times and supports a quick charge of around four hours for minimal downtime. The package is ready to use out of the box, including battery, cable and microphone tape.
