Earlier this month Plantronics posted a teaser site hinting at what they called their most advanced headset. The official announcement is pegged for April 23rd and the site features teaser pics. In anticipation of the announcement it looks like Plantronics shipped the headset to retail stores but forget to stress the release date. Over the weekend two Best Buy customers managed to purchase the Voyager PRO Bluetooth headset and sent images of the device to Engadget. We still don’t know what all the hoopla is about, but at $120 it better be damn amazing.
