U.S. COMPANY, U.S. SUPPORT — Eartec is a U.S.-based professional communication brand with direct manufacturer warranty and U.S.-based customer service. When you need help, you reach people in your time zone — not an overseas reseller. The Eartec UltraLITE UL4S is a professional 4-person wireless intercom system for crews who need real conversation, not radio chatter.

The UL4S is a full-duplex intercom designed for 4 users who need to communicate hands-free. The system uses Digital Enhanced Cordless Technology (DECT) on the 1.9 GHz band to deliver simultaneous wireless communication within a quarter-mile range. All electronics — including the battery — are built into the headset earcup itself, eliminating the wires, beltpacks, and base station that older intercom systems require. Each kit includes four single-ear headsets, four rechargeable lithium batteries, a multi-port charger, and a softside carrying case.

The UL4S is in daily use across film and TV production, broadcast operations, stage and live event work, coaching staff communication for football, soccer, and other team sports, marine and boat operator coordination, drone team flight operations, RV and trailer crews, and small production teams that need a wireless headset solution without complexity. Whether you're calling cues from a director's chair, coordinating a coaching headset hand-off on the sideline, working a boat headphones with mic setup on the water, or managing drone team communication on location, the UL4S delivers professional intercom performance.

Eartec is a U.S.-based company with U.S. customer support and direct manufacturer warranty. The UL4S is field-programmable and expandable up to 5 users. No FCC license required.
