Journey to new worlds with the VR One Plus Virtual Reality Smartphone Headset from ZEISS. This headset works with your smartphone to give you access to immersive 3D videos, games, and augmented reality. Just slip your smartphone into the custom-made tray, insert the tray into the VR One Plus, and you're ready to go. Thanks to its specially designed "eye-box," users don't have to make any mechanical lens adjustments to account for different interpupillary distances, meaning the VR One Plus can be worn with eyeglasses as well. Ventilation ports are built into the headset to prevent fogging, and openings in the smartphone tray allow you to hear your smartphone's audio clearly.
