There are actually like 10 exact same glasses from different manufacturers/brands, from 250-ish moneys upwards (you might need various addition interfaces for your devices, like PC, HDMI, etc - sold separately and unreasonably expensive for what they are).
They all use the same design, Sony OLEDs, speakers, batteries, accessories, etc, they only differ in front design.

I wish we had better open source options. I don’t want to download Chrome to update firmware on stuff.
