UltraLITE 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 does not require complicated base stations users can remain in constant full duplex voice contact even while on the move.

Standard UltraLITE 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.

EVADE are a new class of light industrial wireless team communication systems designed for professional crews that need immediate, hands-free voice contact. By operating in full duplex mode they allow crews to talk simultaneously and hands-free.

EVADE headsets are self-contained with a compact full duplex transceiver built inside the ear cups eliminating wires and belt packs. Each complete intercom includes one “MAIN” headset that relays the digital signals generated by up to eight “Remotes”. The headsets link automatically without a base station making the EVADE series easy to operate, reliable, and affordable.

A digital wireless technology known as Frequency Hopping controls the operation of all EVADE intercoms. These specialty headsets monitor the surrounding environment and switch or “HOP” automatically to clear channels. This is the same wireless protocol utilized by the U.S. Armed Forces to keep communications completely secret and interference-free.

The Conference Module provides a staff conference with a single touch of a button.

  • Outstanding comfort
  • Up to 32 users in full duplex
  • 800m range
  • No base station required
  • Automatic frequency hopping for interference-free comms
  • XTreme hard-hat compatible model available
  • Field programmable






E-Pak is the most dynamic product Eartec has engineered in their 60-year history. This compact full duplex transceiver provides hands-free, simultaneous talk communication and includes a second RF module that allows use of lightweight wireless headsets. This versatility accommodates personnel that need discreet communication free of traditional plug-in wired headsets.

These lightweight, digital transceivers can be worn tucked inside a pocket or clipped to clothing. To operate simply snap in a charged Li-poly battery (included), turn the units “ON” and pair one of Eartec’s wireless headsets.

E-Pak have the same frequency hopping technology as the Evade series, meaning they only transmit on frequencies that are clear. Therefore, multiple E-Pak systems can easily work in harmony in the same venue and without interfering with other wireless equipment.

E-Pak features:

  • Mute switch
  • 275m range
  • Up to 9 users
  • Weighs only 70g
  • Wired headsets optional

The Lazer-Pro headset transfers audio through bone conduction, which means signals are received as vibration through the skin, leaving your ears free to monitor surrounding activity. This headset also has volume control built into the discreet mic boom.






Eartec Glossary

Full Duplex –  Mode of communication where transceivers can send and receive signals simultaneously. Provides hands-free, open-line talking pattern.

Simplex –  Traditional Two-Way radio mode of wireless where users take turns talking. Transmissions are typically initiated by pushing a button (PTT).

Voice Activated (VOX) – Setting available for some simplex radios where user's voice initiates a transmission instead of pushing a button. Voice-activated DOES NOT allow users to talk simultaneously.

Digital Transmission – Microprocessor converts voice into a digital signal. Transceiver uses this digital Code, 1’s and 0’s, instead of traditional analog radio waves.

Base Station – A centralized signal relay that connects remote transceivers in a full duplex wireless intercom.

DECT – Digital Enhanced Cordless Telecommunications – Utilized worldwide for non-licensed interference free, digital voice communications.
