A partially implantable hearing device comprises a microphone assembly to be worn by the user for capturing audio signals from ambient sound, an audio signal processing unit for processing the audio signals captured by the microphone and an implantable assembly with a power supply and an electromechanical output transducer for stimulating the user's hearing according to the audio signals processed by the audio signal processing unit. Also a microphone assembly provides for transcutaneous transmission of audio signals captured by the microphone assembly to the implantable assembly and for transcutaneous transmission of power to microphone assembly from the implantable assembly.
