AR glasses for travelling.

Hey guys,

I am quite new to the world of AR glasses. I am after a pair of glasses that I can take on flights and travelling for content viewing, not really fussed with gaming - but rather glasses purely for watching YouTube videos, series or films.

What are the best ones for this instance? I have heard of things like 3DOF. I want ones that are non fatiguing and less likely to induce motion sickness.

I have seen so far the 3s Air and the 4 Air Pro, which one would you recommend?
