Do I need to buy a headset to watch VR tours and videos?

 


NO


On computer screen, grab the image with mouse and rotate it in all directions.  
On mobile, make it full screen, hold in in front of you, and turn around yourself to enjoy the view from all sides.  
In VR headsets (Mobile based), click on the VR icon on the tour screen and it will make the images into 2 parts.  Put your mobile in the VR headset, wear it and roam around to get the experience.
