## Description

The Eartec UL312 is a professional full duplex intercom for three people that need to communicate and work with their hands. This compact system features three UltraLITE wireless headsets, one single-ear “Main” that sets the digital sequence, and two dual-ear “Remote” headsets. UltraLITE utilize Digital Enhanced Cordless Technology (DECT) to provide professional, simultaneous wireless communication within a quarter mile range.The UltraLITE series are a breakthrough because all electronics, including the battery are built right inside the headset earcups, eliminating wires and belt worn radios. The system does not require a base station, and the headsets are field programmable, meaning that the system can be expanded at any time.No FCC License Required

Review: Sounds great..comes with charger that only charges 2 batteries at a time...with 3 headsets i somehow thought maybe only 2 of them had batteries lol but once i figured that out...i just charge 2..then the 3rd afterwards..not a problem..i recommend these headsets for coaches and their staff
Review: I was skeptical before I received these Eartec headsets but once we used them, all I can say is WOW! they work and they work well. We use them outdoors and the wind is always blowing. The Eartec UltraLITE's were crystal clear for voices while the background wind was hardly noticeable. I only wish I knew how good they were because I would of purchased a larger system.
