Yes, I did a review on AirCaps. I'll copy it here for you:
AirCaps:
Looks: clunky. Looks better with the clip-on sunglasses I bought at Walmart. Also easier to see the display in bright situations. But you must try the sunglasses on in the store, as the glasses frame is very thick where they clip on. With both glasses and sunglasses on, a bit heavy but okay. Not for long hours of wearing though.
Worked very well while in the dentist’s chair! Also in the car. I could drive and also carry on a conversation. I don't notice much latency. Maybe a bit.
I mostly use them offline, and they work well. Still need the phone close by. (The only glasses that work offline.)
In table conversations I get the double vision display. I talked to their reps about that and they said they are made for longer distance viewing. So you have to focus past the persons you are talking to.
Battery: For me they’ve been lasting 2 hours. I turned down the brightness and that helped some. I have ordered the extra batteries and we’ll see how that goes. Since there are the only CC glasses I’ve found that work offline, I’m hanging on to them. I would love to find some that are smaller, longer battery, and work offline. Maybe next year. I did tell the AirCaps reps that it would be nice to have the time and sounds showing.
