The camera is worse than any phone camera and you have been able to buy headphones with active pass through forever to “hear the world around you” including adaptive ones.

And being sensitive sweat is kind of a deal breaker when you are working out.

The advantage for me is being able to snap video without holding anything in my hands. Sure, I could do that with a Go Pro but with these I just throw them on. I find the video quality to be good enough... the few moments I've captured have been so outstanding that I don't really care that it's not 4K.
