Tal Drori created this Coniglio Hat (coniglio means "rabbit" in Italian) with a built in earphone for listening to music.
When the ears are down, the music player automatically turns on. When the ears are up, the music player turns off, and this position signals that the wearer is attentive and ready to communicate with the outside world.

But then again, we girls can get away with a LOT more than the guys. Who... just might be labeled as gay,immature, or *gasp* furry. :P
