You might be thinking about pure graphene diaphragm - sure, that would be crazily expensive. But the so called graphene diaphragm that is coming to the headphone market right now are really composite diaphragm that contains graphene. Those are not that expensive.
Do you have any more info on this? The stuff I find from suppliers in China is still very expensive, even in bonded form with PET film.
