Eartec HUB541 UltraLITE Wireless System - 1 HUB Full Duplex Transceiver, 1 ULDR Dual Ear DECT Headset, 4-Pack of ULSR Single-Ear Remote Headsets

The HUB is a revolutionary full duplex, mini base station that weighs only 9 oz. and can either be placed strategically "on location" or belt worn. When clipped comfortabely to the waist it moves seamlessly with your group allowing users to remain in constant full duplex voice contact.
The HUB features two channels, utilizes rechargeable Lithium batteries, and operates in the license free DECT band. It connects up to six UltraLITE wireless headsets in full duplex mode within a 400 yard range. The dual pin jack allows addition of an EARTEC wired headset to increase the talk net to seven users.
UltraLITE are breakthrough full duplex wireless headsets that provide hands-free, two-way voice communications. At the heart of these systems is a specialty "aster" headset that relays the digital signals generated by up to three "emote" units. The resulting open line talking pattern allows up to 4 people to talk simultaneously without pushing buttons. To formulate your standard UltraLITE system select any combination of Double or Single ear headsets - up to 4 units.
UltraLITE Double headsets allow users to remain in constant full duplex voice contact even while on the move. What sets them apart from most other wireless headsets is that they operate without belt pack transceivers. All electronics, even the battery, are installed right inside the ear cups. The UltraLITE Double includes deluxe padding and fully adjustable noise cancelling microphone to insure effective voice communication even in high noise environments.
