be not much between the ears

To be rather stupid, dull, or dimwitted; to not have much common sense or basic intelligence. She seems nice enough, but I get the sense that there might not be much between the ears. Jake's boyfriend is incredibly attractive, but there isn't much between the ears from what I can tell.
