Eartec ULDM Overview

UltraLITE Dual-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 effective voice communication even in high-noise environments.
