Envoy Medical Announces Completion Of First Set Of Activations In Final Stage Of Pivotal Clinical Study For Investigational Fully Implanted Acclaim Cochlear Implant

Momentum continues to build for Company as series of clinical milestones are met, design choices cement differentiation from competition, and timeline comes into focus

White Bear Lake, Minnesota--(Newsfile Corp. - December 10, 2025) - Envoy Medical® Inc. (NASDAQ:COCH) ("Envoy Medical" or the "Company"), a hearing health company pioneering fully implanted hearing solutions, today announced the completion of the first set of activations in the final stage of the pivotal clinical study for the investigational fully implanted Acclaim® cochlear implant.

These activations were performed at Shohet Ear Associates in Seal Beach, California and the Center for Neurosciences Ear and Hearing Center in Tucson, Arizona, two of the seven investigational sites involved in the study. While specific hearing results from these activations cannot be publicly disclosed until the trial is completed, Envoy Medical notes that no serious adverse events were reported and that the team is pleased with how the activation appointments went.

The Acclaim® cochlear implant is an investigational first-of-its-kind cochlear implant designed to leverage the natural ear - not a microphone - to capture sound by using a combination of the Company's proprietary implanted piezoelectric sensor and the body's natural anatomy.

Unlike traditional, partially-implanted cochlear implants, the fully implanted Acclaim® cochlear implant does not require a bulky external component to function. In addition, the fully implanted Acclaim® cochlear implant also does not have an implanted magnet to attach external components to the side of the patient's head, as there are no external wearable components required to hear with the Acclaim® device.

Moreover, the design of the Acclaim® implant allows for several days approximately four to five days between any required recharging of the battery. The Acclaim® device design also has a removable battery pack that can be replaced by itself without requiring the full system to be explanted.
