The Speck Pocket VR is a foldable Google Cardboard virtual reality headset
8

Have you ever come across a product that made you say to yourself "how did nobody come up with this earlier"? Even if you haven't, the Speck Pocket VR is one such contraption. The accessory functions as a virtual reality headset, as you can probably tell by the images. It is certified for use with content made for Google Cardboard headsets. When it isn't in use, however, the Pocket VR folds to fit in a pocket for easy carrying. Neato!
Without a doubt, the Speck Pocket VR's main selling point is its portability. It isn't much bigger than a smartphone case when folded and makes a typical Google Cardboard viewer even bulkier than it already is. On the flip side, the accessory appears to be designed around the Speck Candyshell Grip case – you'll need to have the latter in order to use the Pocket VR. Still, that's not too big of a drawback, as Speck's case is a pretty good one.
