The Zeiss VR One Plus Headset is a passive virtual reality headset with a solid build for your iOS or Android smartphone. It’s a nice upgrade from your Google VR cardboard headset and supports larger format smartphones from 4.7″ to 5.5″. The VR One Plus is basically Google VR Cardboard, but a nice one. The unit looks polished with a premium feel and is very comfortable to wear. The fit is a bit top heavy depending on what device you have inside the tray, however they’re all like that to a degree.
