Virtual reality is getting pretty trendy but options are pretty much limited to the Oculus Rift or variations of it – that is until now. Zeiss is offering a cheaper alternative to the Oculus with the VR One.

The VR One syncs with the iPhone or Android-based smartphones to offer 3-D viewing of photos and movies. The headset will be compatible with all smartphones as long as the display is either 4.7 inches or 5.2 inches.

The Zeiss VR began shipping earlier this month. You can order one for $99 here.
