Samsung You'll get a free Gear VR headset if you pre-order the Samsung Galaxy S7 or S7 Edge, according to a report from Android World.

The Gear VR is a virtual reality (VR) headset that uses Samsung's latest flagship devices, including the Galaxy S6, S6 Edge, S6 Edge+, and Note 5, to play VR content.

The content plays from a compatible Samsung phone, and the Gear VR headset uses optical lenses to focus that VR content.

VR makes for a more immersive experience compared to playing or watching content on a flat screen, as your entire field-of-view is taken up by the content playing from your phone.

Here's a basic gist of the way Gear VR works with a Samsung smartphone:

With the Gear VR and a compatible Samsung smartphone, you can play VR games like the beautiful "Land's End" (from the makers of "Monument Valley"), as well as other videos and VR experiences. And because your entire field-of-view is taken up by the content and you have total control of where you look, it really feels like you're "there."

Normally, the Gear VR costs $99 to buy if you already have a compatible Samsung smartphone. If you don't, you'd need to buy one of those aforementioned flagship devices to use the Gear VR, which could cost you $650 or more, depending on which model you'd buy.
