The Oculus Quest is the next iteration of VR headsets. It sits in between the Oculus Go and the Oculus Rift or HTC Vive in terms of power and visual fidelity. This does not mean that it is a bad device, it just means that it is not able to go as deep in the quality and performance than the computer connected devices such the Oculus Rift will be able to. It features a Qualcomm Snapdragon 835 processor along with a decent 1600 x 1440 per eye display resolution. This is higher than most other devices on the market, but will not do away with the screen-door effect.
It includes a similar in-ear speaker system as the Oculus Go, which vastly improves the immersive experience. With a cost similar to the Oculus Rift, it will lower the bar significantly as it does not require a powerful PC to run VR.
