Eartec Co UL3D
UltraLITE 3-Person System featuring 3 Double Headsets


The Eartec UL3D is an UltraLITE 3-person system with (3) UltraLITE Double headsets, batteries, and carrying case.

UltraLITE Double Headset
These offer hands-free, 2-way voice communication, letting users remain in constant full-duplex voice contact, even on the move. What separates these from most other wireless headsets is that they're used without belt-pack transceivers; all electronics, including the battery, are located right within their ear cups. They come with deluxe padding, and include a position-adjustable noise-cancelling microphone to ensure effective voice communications, even when used in high-noise environments.

Eartec's Standard Softside Case
This compact headset bag/case is made for safe storage of your UltraLITE wireless intercom. Made of waterproof nylon material, it features padded internal compartments to keep the headsets organized. Additionally, there's a pocket with a hook-and-loop closure mechanism for the charger (charger sold separately) as well as any spare batteries. Its molded hard-plastic handle makes transport easy and convenient for on-location work. In sum, there's no better way to protect your Eartec wireless system investment than with this quality accessory.
