Pimax 4K, released 2017. For use with a PC. 4K display resolution (1920x2160 per eye). FYI this headset does not have 3DoF tracking or controllers! Probably best for watching 3D videos.

The hdmi connector is slightly pulling away from the housing but it still works (hdmi and the headset working are pictured). The surface of the cushion for the back of your head is also coming off.
