Somnium Space VR ONE is an unreleased tethered PC VR headset with incredible visual immersion from 2880x2880 pixels per eye within a 120-degree horizontal FoV - no theater effect with this virtual reality headset. But best of all, Somnium Space VR ONE is an enthusiast HMD for the invested prosumer as the hardware and software are fully interchangeable, with its 3D models being open source for 3D printing replacements and upgrades. A truly unique VR headset.
