AirPod vs. AppleCare Pondering

I can't help but wonder

I’ve been told in the past at the Genius bar that my Airport Express was covered under the AppleCare of my rMBP (AE replaced).  I’ve heard similar discussions while sitting at Genius bar about other items.

So… the question.

I have AppleCare on my iPhone.  I’ve ordered two sets of AirPods….  Should one  AirPod encounter water damage, or drop damage, or ‘whatever’, is it similarly covered?  Alternatively, do they sell AppleCare ‘just for AirPods’?  I wasn’t given the option when pre-ordering.
