The design of the original View-Master Virtual Reality Viewer also restricted access to a smartphone’s headphone jack, meaning you had to rely on speakers that were blocked and muffled by the housing. So the 2.0 model includes a headphone jack adapter that accommodates phones with the jack on the top or bottom.
The View-Master Virtual Reality Viewer 2.0, available this fall, does see a price bump to $40. But it also now incorporates a focus wheel allowing the lenses to be adjusted for sharper results. And the viewer’s latch has been completely redesigned, since the original had the tendency to pop open at the worst time which increased the risk of a smartphone falling out to its demise. No virtual reality experience is worth that.
