  • Fully Adjustable Noise Cancelling Mic
  • Deluxe, Padded Ear-Cup Design
  • Eliminates Wires and Belt-Worn Radios
  • Provides Hands-Free Communication


The UltraLITE Single-Ear Master Headset with Rechargeable Lithium Battery from Eartec is a self-contained, replacement full-duplex wireless intercom headset. It can be used to provide simultaneous talk and two-way voice communication for users that need to work with their hands, yet also require one ear free to listen to what is going on around them.

The system eliminates belt-worn radios because all electronics are built into the ear cups. The fully adjustable noise cancelling microphone ensures effective voice communication.

Please note: This will be the HD version of the headsets, which are not compatible with the older Classic version. Please contact us if you wish to order Classic versions.

  • Eartec UltraLITE units require a minimum of at least 2 headsets to communicate. A working system requires 1 Master and at least 1 Remote. Master and Remote headsets are sold separately. This is a Master headset that will only work with at least 1x Remote headset. Up to 4 Remote Headsets can be used with 1x Master Headset, without the requirement of a HUB.
  • Master headphones cannot be used together with the HUB.
  • Current Eartec UltraLITE HD version headsets are not compatible with older (non HD) models.
