Are the EP-B40s still available?

My almost 2 year old set recently started to fail (intermittent left / controller side), so I decided to just get another set. Alas, I can’t seem to find them anywhere—and the set of EP-B56 I got instead are, in my opinion, a downgrade in almost every regard.

I’d rather get my trusty old EP-B40s repaired / replaced if possible, so I’m trying to determine what options I may have.
