Meh, you can immerse a transistor radio or headset in bathwater to no ill affect (to you anyway, the electronics might get rather soggy and gross). In fact, though, they'll probably just keep running.
I dunked a cheap walkman once, and the thing just kept playing, freshwater isn't conductive enough and the voltage isn't high enough to make much of a difference.
@Keo No, contrary to popular belief, the Vocaloid characters aren't robots. There was, however, a song/video where their souls were transplanted into robot bodies and they go on a grief-fueled killing spree.
