Well I've never heard earphones being referred to as "beats" but okay. At first I thought you meant some songs by Dr Dre, and thought, who'd want that?!
Anyway, star... lots of things you could do with that. Depends how you interpret the word. Could mean a literal star in outer space, or a celebrity. I would use the outer space type, as they look pretty awesome. To be honest I don't have any further ideas though, but good luck.
