What is the Graphene earphones?
Earphones using graphene offer superb frequency response. The reason for this is down to the graphene diaphragm’s simplicity: Most diaphragms/cones must be dampened to prevent undesirable frequency responses, graphene requires no dampening. This is because graphene is so strong that the diaphragm can be incredibly thin — and thus very light. Instead of being artificially dampened, the graphene diaphragm is dampened by the air itself. Graphene is also very energy efficient which leads to reduced power consumption.
