Eartec Co UL4D
UltraLITE 4-Person Full-Duplex Intercom System

OUR PART #  UL4D


The Eartec UL4D is an UltraLITE 4-person system with (4) UltraLITE Double headsets, batteries, and carrying case.

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

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