the trick is to pull the scrotum taut with one hand, and use one of those ladiy razors. i take care of most of it at the tail end of a hot shower, but that won't get them all. to really finish the job, you need to dry off and get a little cold, so that the scrotum scrunches up and the remaining ball hairs stand on end. then just really carefully nip them as close as possible with the lady razor. you're welcome.
