Vuzix Wrap 920 Video Display
The makers of the Wrap 920 video display say that it gives you a portable big-screen video experience. The display in the eyepiece supports standard 2D video as well as most common 3D video formats. Two AA batteries support up to 3 hours of continuous use.
An optional video adapter cable connects the 920 to any of a number of portable media players, including your smartphone or your PC. Vuzix includes removable noise-isolating earbuds in the package.
