First, you must know you have to log in with Facebook to use any Oculus headset, since the company was absorbed by them and it’s just a Facebook brand right now. Second, Oculus Quest 2 is the same price and has better specs no matter how you look at it (60% higher resolution), plus it can be used wired, wireless or without PC so I strongly suggest buying that (Rift S is only that low because they stopped producing them and are trying to get rid of stock). Only problem with Quest 2 is it’s not that comfortable for long 2+ hour flights so you’d have to look into comfort mods (maximum 40 extra bucks).
Before investing, I would suggest watching some reviewers of the various VR headsets out there. Many factors go into your experience, from comfort to resolution. Every person is different and for me, I would want a higher eye resolution. I currently have an Odyssey Plus which has a higher resolution than the Oculus Rift S but if I had the money, I would look at the new G2.
