Xpand is taking pre-orders on its Universal 3D glasses at Amazon with availability expected “in the next week or two,” a company spokesman told us. The glasses will come in one size with multiple nose pieces for adjustment, he said, and use replaceable CR2032 batteries. Introduction of the universal active-shutter glasses, which are said to work with “any 3D-ready display, regardless of brand,” could spark a price war in the active-shutter 3D glasses segment. When we put the Xpand glasses in our Amazon virtual shopping cart, the price showed up as $129.42. We did the same for a pair of Panasonic TY-EW3D1OU 3D glasses. Those glasses came in at $108.88, and within an hour, the price of the Xpand glasses in the cart dropped to $107.67. Samsung SS-G2200AR glasses appeared in the cart at $160.97.
