just stumbled over this post:

(from the new 60404: Burger Truck Set)

as someone with "normal" hearing aids this one is also very nice...
(and there are also minifig heads with the normal ones:

the hearing aid could be subfiled to be used in all heads)

found the heads with the printed hearing aids in Studio (but not on the PT), any way to extract them?
   
where do they get their stuff from?
