New app lets cochlear implant users tune hearing from home
NCT ID NCT06543953
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a smartphone app called HearCare MED-EL that lets people with cochlear implants adjust their audio processor and check for device problems remotely. 120 adults who already had a MED-EL implant for at least 3 months took part. The goal was to see if the app works safely and reliably for managing hearing devices without needing an in-person visit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age \> 18 years * Implanted with at least one MED-EL Cochlea Implant (CI) for at least 3 months * Fitted with at least one audio processor compatible with the HearCare MED-EL App (i.e. SONNET 2, SONNET 2 EAS, RONDO 3 or newer) * Signed and dated Informed Consent Form (ICF) before the start of any study-specific procedure Exclusion Criteria: * Lack of compliance with any inclusion criteria * Implanted with C40X and C40C * Implanted with an Auditory Brainstem Implant (ABI) or Split electrode array * Anything that, in the opinion of the Investigator, would place the subject at increased risk or preclude the subject's full compliance with or completion of the study (e.g. psychological disorders, neurologic or motoric comorbidity that could restrict subjects from using the app)
