I picked up a set of AR glasses for my last flight and was surprised how much of a game changer they were. I plugged them into an older Samsung phone and the Samsung Dex software let me switch the main phone screen off. This gave me something like 9 hours of video time on a larger screen that I could watch in any head position, with shows I brought myself.
I got a Viture One on sale last Prime Days for $300. I also have an Xreal Air 2. The Viture One has a better case for traveling - it has a separate compartment for the cord - and it’s better if you want to share it because it has focus controls on the glasses. But I’m still trying to get the nosepieces into the right place to get full top to bottom clarity. The Xreals need a prescription lens insert, but that means they’re better if you want to use them as real glasses, and the nosepiece is more comfortable and adjustable. The case can hold the cord, but there isn’t a separate compartment so there’s a risk it’ll scratch the lenses. I can’t recommend the Xreal Beam accessory, the battery life is really short.
