Brando has made a “why didn’t I think of that” gadget in the form of their solar powered bluetooth headset. Providing infinite standby time under direct sunlight, you can also charge it via USB through your computer or AC wall plug. You can even buy two of them and use them simultaneously thanks to their stereo matching capabilities. Why would you want to do that I wonder? It would definitely look weird, but you’d at least have sides of your head displaying a bluetooth headset so you don’t look like you’re talking to yourself. On sale now for $67 a piece.
