I got a pair as a gift and didn't look much into them but I have to be honest, I assumed any data I captured - voice, video, etc. - would be sent to their servers (to use their models) and they'd be using it for training with humans in the loop.

Tbh the only thing I really use the glasses for are listening to music or talking on the phone - so basically how you'd use airpods. I don't use airpods because I had an ear injury that prevents me from using them on my left ear, so these glasses were kinda nice for that. I really wish they didn't have a camera though because I do always feel compelled to remove them if I interact with people.

I also have to add that the quality is mediocre. They're a month old and the case has problems charging sometimes, and one of the screws is always coming loose at a hinge no matter how often I retighten that side.
