Eartec ETXC-7 ComStar Extreme 7 Person Wireless Intercom System

Seven-Person Wireless Headset System for Hands-Free Jobsite Communication
The Eartec ETXC-7 is a full duplex wireless intercom system designed for production crews, construction teams, industrial sites, and AV operations where fast, uninterrupted communication is essential. This bundle includes seven XTreme all-in-one headsets and one Comstar Com-Center, allowing up to eight users to communicate simultaneously within a 400-yard range—no push-to-talk delays, no voice activation triggers, and no lag. It’s real-time, open-channel communication that increases safety and productivity.

Self-Contained XTreme Headsets With Built-In Radios and Battery Packs
Each XTreme headset features an integrated transceiver inside the ear cup—eliminating the need for belt packs, external radios, or tangled cables. Designed to be rugged and lightweight, the headsets are built with an adjustable over-the-head strap and durable backband that fits comfortably with hard hats and bump caps. These are industrial-grade tools built for environments where mobility, safety, and comfort matter.

Comstar Com-Center Enables Dual Channel Group Communication
The included Comstar Com-Center is the system’s central transmitter and relay station. It supports two channels, each connecting up to four users, and includes a conferencing switch to link all users into a single conversation. The Com-Center is compact and portable, operating via AC power, a rechargeable lithium-polymer battery, or a disposable AA battery sled—all included for flexible deployment across locations.

Battery Power for All-Day Operation and Fast Recharging
Both the Com-Center and the headsets operate using lithium-polymer batteries with up to 8 hours of runtime per charge. Batteries fit directly into the headsets and snap easily into place. Spare batteries can be swapped in seconds to keep your system running without interruption. The included multi-port charging base allows for simultaneous charging of headset batteries and the Com-Center, with LED indicators to display charge status.

Designed for Challenging Worksites and Safety-Focused Teams
Eartec’s XTreme headset format is ideal for users who must wear protective headgear on the job. The low-profile backband and adjustable support strap sit securely beneath hard hats without compromising stability or comfort. Noise isolation and voice clarity are maintained even in noisy environments, making the system suitable for crane operators, technical teams, stage crews, and utilities.

Quick to Deploy and Ready for Expansion
The ETXC-7 system is self-tuning and requires no remote antennas or calibration. Setup is immediate—just power on and talk. Up to eight users can be supported per Com-Center in full duplex mode, and additional systems can be networked for broader team integration. No FCC license is required, making this a cost-effective and legally compliant communication solution that can be used right out of the box.
