The master WAERO Wireless Duplex Headset from CAME-TV is a component of the duplex (2-way) communication WAERO system. This master unit can be paired with up to three slave units for a total of four headsets or when used with a hub, up to eight slave units, and a hub-linked headset to create a 10-headset system. This component is powered by a replaceable battery in the headset itself, eliminating the need for a bulky, clip-on battery pack.

The only buttons on the headset are for volume and power; to talk, simply swivel the mic boom down to speak and swivel it up to mute. Designed for video production, sports, and events, the WAERO Headset includes one NB-6L type battery and folds for storage. This EU version can be used in European countries and other locations outside North America.
