The Listen Technologies LKS-3 addresses multi-leader communication demands in tour operations, manufacturing facilities, broadcast production, and interpretation environments where eight or more participants require simultaneous talk and listen capability. Each transceiver operates independently within the same discussion group, eliminating the single-talker bottleneck common to traditional push-to-talk systems.

Built for integrators and AV managers supporting complex workflows, this configuration ships deployment-ready with headsets, lanyards, batteries, and a docking station that recharges all eight units simultaneously. The LA-481 case doubles as transport protection and a charging hub, simplifying logistics for rental houses and production teams managing multi-site events. Transceivers pair automatically within range, and the expandable architecture supports adding units to the same talk group as operational requirements grow.
