Does any one have these and actually use them for anything? I was gifted a pair from someone who probably used it for an hour or two and got bored of them. But beyond using them like headphones, or asking what kind of plant I'm looking at I don't understand the use case. The other day an ad for them came up, and I actually watched it thinking oh maybe ill see what they think you should use it for. It might as well have been an ad for normal sunglasses.
