There are a LOT of insider info articles mentioning wireless charging:

I've linked just 3 but you get the idea
The only article the address the metal back and wireless charging is the Forbes article which talks about "smart aluminum" and the oxide layer over plastic. Otherwise I don't see how one charges inductively through metal.
Secondly the use case for headphones like this is a traveler. If the charger is small like the one on the Apple Watch it would be great.
