The XT-Plus Com-Center with Interface and ComStar Single-Ear Headsets from Eartec is a wireless system designed for teams that need to intercommunicate while they work with their hands. The system allows up to eight users to talk with each other simultaneously just like on a regular telephone, with no transmission delay, within a 2400' range. At the heart of the COMSTAR system is a portable signal relay unit called Com-Center. This centralized base transceiver can be either AC or battery powered, and accommodates the eight included headsets. Also included are a multi-port charger, a wall adapter, eight headset batteries, two Com-Center batteries, and a carrying case.
