Standard UltraLITE-HD intercoms provide instantaneous wireless communications for crews that need to communicate without pushing buttons. At the heart of these systems is a specialty base or “MAIN” headset that relays the digital signals generated by up to four “Remote” units. The resulting open line talking pattern allows up to 5 people to talk simultaneously so they can continue working with their hands.
Need more than five crew? Add Eartec’s Mini HUB (replaces your existing MAIN Headset).
UltraLITE-HD are revolutionary headsets that eclipse all other full duplex systems for performance and convenience because the transceiver is built right inside the ear cup. This self-contained, “All in One” design eliminates wires and belt worn radios. And since UltraLITE-HD do not require complicated base stations users can remain in constant full duplex voice contact even while on the move.
Auto Mute Boom Technology
All UltraLITE-HD headsets include EARTEC’s Auto Mute Mic Boom Technology. These specialty microphone assemblies feature an internal switch that automatically mutes the headset mic gain when set to the UP position. Using Auto Mute is a simple and efficient way to mute your microphone signal.
Batteries – Charger – Case – All Included!
A terrific feature of UltraLITE-HD systems is that the Lithium Polymer batteries (included) charge externally and are field replaceable. This allows you to purchase and keep spare batteries on hand extending the run time of your system indefinitely. A multi-port charger is included with each new complete UltraLITE-HD intercom that features positive LED indicators. When the batteries reach full charge the corresponding LED turns from red to green indicating that the battery is ready to go.

The UltraLITE HD is a self-contained, “all-in-one” wireless system, meaning the transceiver is built directly into the ear cup. Unlike traditional systems, there are no belt packs or external wires, providing total freedom of movement for production crews, drone pilots, and industrial teams.
No. For systems of 2 to 5 users, the UltraLITE HD operates without a base station. The “Main” headset acts as the digital relay for the “Remote” headsets, making it highly portable and easy to set up in seconds.
Full Duplex allows all users to talk and listen simultaneously, just like a telephone conversation. This “open line” pattern is essential for hands-free work where pushing buttons to talk (PTT) is not practical.
A standard UltraLITE HD system supports up to 5 users (one “Main” headset and four “Remote” units) in full duplex mode without a base station. If you need to expand your crew, adding an Eartec Mini HUB allows for up to 9 users, while the PRO16 system supports up to 16 users.
The UltraLITE HD features Auto Mute Boom Technology. To mute your audio, simply swivel the microphone boom to the “UP” position. An internal switch automatically cuts the mic gain, and flipping it back down restores communication instantly.
The headsets provide a wireless range of up to 300 yards (line of sight). Actual range may vary based on terrain and environmental obstacles.
Yes. All Eartec UltraLITE HD headsets are equipped with noise-canceling technology to ensure clear voice transmission even in loud environments like concerts, construction sites, or sporting events.
