The Eartec EVADE EVX5D is a full-duplex wireless intercom system suitable for facilitating communication among five people for light industrial applications. This set includes one dual-ear master headset for the team leader and four dual-ear remote headsets. All the technology necessary for operating the intercom system, including the battery, has been built into one of the headset's earcups—eliminating the need for wires or a bodypack. The headsets link automatically for transmission in the 2.4 GHz spectrum at a maximum range up to 1148', and a base station is not required.
