I have several pairs of these glasses from Viture. They’re very good. Not sure how the xreals are. But the technology is legit.
I've used a Hololens before, and it was pretty cool display-wise, but not even remotely worth the price in practice. What would you recommend to use in conjunction with a Steam Deck dock?
Yes absolutely. Very different than HoloLens. They still need to get the fov up a bit higher I think before they explode. But, I often use them for watching shows or playing in my steam deck in bed so I don’t interrupt my partner trying to sleep.
