Do Xiaomi’s new earphones use a graphene membrane for improved sound quality?

The Chinese mobile phone maker Xiaomi recently launched a new in-ear headphones, called ‘Piston 3 Pro’, that according to reports from various websites and blogs makes use of a ‘graphene diaphragm’ that helps in producing more natural sounds. The use of graphene, however, was not mentioned in the Xiaomi official website.

We are quite skeptical about the presence of an actual graphene membrane that enhances the sound quality in this product; It seems possible that Xiaomi is using some form of graphene added to the product but we will wait to find a more formal explanation as to what its role actually is, if any.
