This is certainly not the case if your phone is capable of using AR Glasses. The following have great sound and an amazing picture.

AR glasses are frequently heavily discounted, and they only work with certain phones. I use a 5-year-old Samsung S20+ 5G that I purchased for $150 on Ebay.

I can see myself wearing these, sitting in my easy chair, eating popcorn, and reacting to something that for the rest of the world isn’t there. Nah, I’ll stick with my OLED TV, thanks.
