This compact system features four UltraLITE wireless headsets, one single-ear “Main” that sets the digital sequence, one single-ear "Remote" headset, 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: Good com system for church - We really like our eartec com system. We use it at church and you can hear a whisper in a loud room. I deducted a star because somehow these came unsynced. The syncing process is harder than you’d think and i hd to watch a long youtube video to get it to sync up. There was no manual.
Review: Excellent performance, great for boating. - For the cost of this set I was worried that it would not work well. However I am very pleased with the performance of these headsets. I’m slightly hard of hearing and was afraid the volume would be too low, but that was not the case. These even worked from the engine room of our steel boat through 3 decks to the pilot house. Very pleased.
