Eartec 4 Person Intercom UltraLITE UL413
The Eartec UltraLITE UL413 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 mix pairs one single-sided headset, which leaves an ear open to the room, with three double-sided headsets that seal out loud environments. 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: one single-sided and three double-sided UltraLITE headsets, batteries, a dual charger, and a carry case.
