Like the Samsung Gear VR and the previous Zeiss One, the hardware power for the second-gen Zeiss branded headset comes from your smartphone. Unlike Sammy's effort, however, you're not tied to just one mobile with the Zeiss VR One Plus; it will play ball with any iOS or Android handset with the latest model allowing larger sizes between 4.7 and 5.5 inches (it previously only fit phones up to 5.2 inches).
It packs a media player for the likes of pictures and YouTube videos and an AR app for augmented experiences, while the open source Unity3D SDK (iOS and Android) means there's plenty of scope for development. The company is also pushing for drone enthusiasts to pick up the One Plus headset as a means to fly and see from a bird's eye view - in VR.
What's more, with lens maker Zeiss doing the optics, VR One Plus definitely has promise - however the second iteration is only available in Europe right now.
