Eartec UltraLITE PRO16 ETP4S

The Eartec UltraLITE PRO16 ETP4S is a four-person long-range full-duplex wireless intercom with the transceiver built into each headset, so there is no base station or belt pack to carry. Two independent talk channels let separate groups hold private conversations, and Active Frequency Hopping moves the link to a clean channel automatically to dodge interference. Line-of-sight range reaches up to half a mile.

A PRO16 network links up to 16 headsets in full duplex, and this bundle covers four of them: four single-sided headsets that leave one ear open to the room. Hi-capacity lithium-polymer batteries deliver up to 10 hours per charge and pop out for fast field swaps. In the box: four single-sided headsets, batteries, a 10-port charger, and a carry case.
