Eartec UL4D UltraLITE Full Duplex Wireless Intercom 2 Way Communication System for 4 Users - 1 ULDM Dual-Ear Master Headset and 3-Pack of ULDR Dual Ear Remote Headsets

Consumer Alert: Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.

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.
