A few threads ago I asked if Gear VR is worth it. Anon recommended against it, but I bought it anyway. Setup was pain (forced FB account), my cheap USB Ethernet NIC turned out to throttle below 10 Mbps after some time so I have to rely on connecting the phone via WiFi, phone can't be charged while in headset, screendoor is noticeable, OLED pixels turning on from full black is a bit visible. 
But! It's super fun with Elite Dangerous. Latency even on WiFi is minimal, resolution is pretty okay (switched the Note9 to 1440p), FoV is alright in-game. I mean, man, it's cool as fuck to just fly and look around at other ships or docks.
Any other sitting games you could recommend, anons? I'm thinking about trying some racers with a borrowed steering wheel.
