I'm not too familiar with those. Top of my head reaction to Googling them just now is that I can't stop feeling there's something a little sneaky about them. "What? these totally normal looking yet suspiciously thick sunglasses? No no no... I'm totally not filming you right now".

I think if it's a VR contraption then it needs to be honest about it which is why the Beyond 2 seem to be going in the right direction. I just re-watched a review of the B2 and saw that it only weighs 110g (less than a peach) which is so much less than the Apple Vision Pro at 600g. I'll definitely be keeping an eye on how the VR industry decides to compete with the B2.
