The Eartec UL532 is a full-duplex wireless intercom suitable for facilitating communication among five people. It comes with one single-ear master headset for the team leader and two single-ear, and two dual-ear remote headsets for everyone else. All technology necessary for operating the intercom system, including batteries, has been built into the headset's ear cups. This eliminates the need for wires or belt-worn items. Five rechargeable Lithium batteries, an eight-bay multi-port charger, and a soft-side case are provided.
