Eartec UPSST7 UltraPAK & 7- SST Headsets

Complete Wireless Intercom System for Seven-Person Teams
The Eartec UPSST7 is a professional-grade, full duplex intercom system built to support hands-free communication for seven users. This kit includes one HUB Mini Base Station, seven UltraPAK beltpack transceivers, seven SST (Secret Service Type) headsets, seven rechargeable lithium batteries, an 8-port charger, and a medium soft-sided storage case. Designed for production teams, event crews, sports coaches, or any group requiring seamless communication while staying mobile, this system delivers clarity, portability, and reliable wireless performance.

Expandable Wireless Coverage with the HUB Base
At the center of the system is the HUB Mini Duplex Transceiver, designed to expand your intercom coverage by over 1000 feet. It can be worn on a belt for mobile operation or placed at a fixed location for centralized communication. The HUB supports up to 8 wireless UltraPAK or UltraLITE headsets simultaneously. Featuring Digital Enhanced Cordless Telecommunications (DECT) technology, the HUB provides interference-free communication and offers dual-channel operation. With both battery-powered and AC options included, it adapts to on-the-go use or permanent setups without needing an FCC license.

Lightweight UltraPAK Beltpacks for Comfortable Communication
Each of the seven included UltraPAK units is a compact beltpack weighing just 2.5 ounces. These ergonomic transceivers offer up to six hours of continuous operation using the included lithium batteries. Controls are user-friendly with individual volume adjustment and a mic mute button featuring an LED indicator. Paired with the SST headsets, the UltraPAKs provide reliable full duplex communication over distances of up to a quarter mile—ideal for fast-paced, team-coordinated environments.

Discreet and Clear Audio with SST Headsets
The SST headsets offer a sleek, low-profile listening experience that blends into environments where discretion is key. Featuring a coiled acoustic tube and soft earbud, these headsets are often used by coaches, instructors, and stage crew professionals. They connect via dual 3.5mm and 2.5mm plugs and feature a 3-foot cable. The lightweight, single-ear design provides secure and comfortable wear for extended periods, without obstructing ambient sound awareness.

Reliable Power with Hot-Swappable Lithium Batteries
The UPSST7 system includes seven field-replaceable lithium batteries—one per beltpack—and an 8-port charger that allows for simultaneous charging. LED indicators provide charge status at a glance, changing from red to green once batteries are ready. The external charging design ensures that backups can be cycled in quickly, allowing uninterrupted communication during long events or shifts.

Convenient Storage with a Soft-Sided Carry Case
Everything in the UPSST7 system fits securely inside the included medium soft-side case. Made from waterproof nylon, it offers custom compartments to organize headsets, beltpacks, and accessories. A dedicated pocket with hook-and-loop closure keeps the charger and spare batteries secure, while a molded handle allows for easy transport to any job site or event location.
