The Eartec UL2S UltraLITE is a two-person, full-duplex wireless headset system for hands-free, two-way voice communication. It includes two single-ear headsets. One is a specialty "Master" headset that relays the digital signals generated by up to three "Remote" units.
The open-line talking pattern lets up to 4 people talk at the same time without pushing buttons. A standard UltraLITE system can combine any mix of double or single ear headsets, up to 4 units.
Each headset is self-contained, so there are no wires or belt-worn radios. The mic boom swivels 270 degrees, so the headset can be worn on the left or right ear. It uses DECT digital technology and needs no FCC licensing.
