A microphone assembly includes a shaft element that is configured to be received in an opening defined by a base substrate layer of a headliner. The shaft element defines an air path. The microphone assembly includes a microphone element mounted on a circuit board within a housing. The microphone element is aligned with the air path such that the air path directs sound from the cabin to the microphone element. A vehicle cabin side of the headliner is covered by an acoustically transparent layer such that the microphone assembly is not visible within the vehicle cabin.
