MET, a semi implantable hearing system, consists of an internal and external component. The internal component is implanted under the skin, and the external component includes a button with a microphone and a battery unit. The MET semi implantable hearing system captures sound through the external microphone and sends it to the implanted capsule, where it is converted into signals that produce a vibration in the ossicular chain through the use of a transducer, generating a high-quality, natural sound. The MET semi implantable hearing system is a viable treatment option for sensorineural, conductive and mixed hearing loss.
