Sansa has unveiled their impressive 3D glasses which are not restricted for use for particular brand alone. The high quality glasses can recognize 3D signals coming in from any 3D TV, be it Sony, Panasonic, Toshiba or Sharp. We do get glasses when we buy these televisions sets, but owing to frequent mishandling, those might be rendered useless. Calling for an extra pair from the manufacturer could turn out to be an expensive affair. Sansa’s offering scores above all of these disadvantages. It is reasonably priced at $100. The glasses have been tested on several TV models to prove their universal functionality. It has inbuilt battery which can be charged via a USB cable. It weighs almost 55g and comes in three sizes of Small, Medium and Large. It ships with a nosepiece, cloth for glasses, USB charging cable and a pouch for safe storage.
