VXi UC ProSet LUX™ Finally, true UC telepresence!To help you get the most out of your Unified Communications system, VXi created the UC ProSet LUX. The UC ProSet LUX starts with the "in-a-class-by-itself" benefits of our UC ProSet, then adds stereo Hi-Fi sound (with DSP) and the plug-and-play convenience of a USB interface. The first headset with a built-in LED presence indicator designed around UC standards, the UC ProSet LUX is lightweight and comfortable enough to wear for hour after hour. Put it all together, and you get the best Unified Communications headset value money can buy-at a price that will surprise you. A monaural version is also available.
