Eartec UltraLITE 4-S Wireless Intercom with Four Single-Sided Headsets

The Eartec UltraLITE 4-S is a four-person full-duplex wireless intercom that works without a base station. Each headset carries its own DECT 6.0 transceiver in the ear cup, so operators talk and listen at the same time, hands free, the way a phone call works rather than a push-to-talk radio. Line-of-sight range reaches 300 yards, enough to keep a four-person production or event crew connected across a venue without belt packs or cables.

This system ships with four single-sided headsets, which cover one ear and leave the other open so operators stay aware of the room while they talk. The lithium batteries charge externally and swap out in seconds, so a spare set runs the crew past the 5-to-6-hour battery life. In the box: four single-sided UltraLITE headsets, four batteries, a dual charger, and a carry case.
