The USA version UltraLITE Single-Ear Remote 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.
