Eartec EVADE EVX4S Light-Industrial Full-Duplex Wireless Intercom System with 4 Single-Ear Headsets (2.4 GHz)

The Eartec EVADE EVX4S is a full-duplex wireless intercom system suitable for facilitating communication among four people for light industrial applications.
This set includes one single-ear master headset for the team leader and three single-ear remote headsets.
All the technology necessary for operating the intercom system, including the battery, has been built into the headset's earcup - 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 station hub is not required.

The microphone boom on each headset swivels up to 270°, allowing the user to wear it on the left or right side. Rotating the boom into the up position automatically mutes the microphone, and a simple, five-level volume control is easily accessed on the earcup.
Power is supplied by a built-in rechargeable LiPo battery, which will power a headset for up to 8 hours.
Four rechargeable batteries, a nine-bay multi-port charger, and a soft-side case are provided.
