AudioKey 3
MED-EL Elektromedizinische Geraete GmbH
A remote-control and usage-information app for compatible MED-EL cochlear-implant audio processors.
What AudioKey 3 does
AudioKey 3 puts supported MED-EL processor controls on your phone. It lets you adjust volume, select programs, locate a misplaced processor and view usage information. A myMED-EL account is required. Some processors connect directly, while others need AudioLink; the supported processor variant and phone setup matter.
How it compares
MED-EL’s counterpart to Nucleus Smart
Like Cochlear Nucleus Smart, AudioKey 3 is a device companion with controls and usage information. It works with supported MED-EL processors; the apps cannot be swapped between manufacturers.
Processor management rather than Audio2Ear media streaming
AudioKey 3 needs internet for registration, pairing, location and statistics functions. If your goal is to stream phone media through AudioLink, Audio2Ear provides that separate workflow.

App Store ratings & reviews
Complaints
- Reports from 2025–2026 describe pairing, reconnecting and bimodal-setup difficulties; the newest report concerns one SONNET 3/Starkey setup and is not a general compatibility finding.
Mixed reports
- Several reviewers find everyday controls slow or limited, while one March 2025 reviewer likes the cleaner, simpler interface. These are user preferences across different releases.
Google Play ratings & reviews
Praise
- Other reviewers describe working controls or improvement after moving from AudioKey 2, sometimes with remaining intermittent problems.
Complaints
- Sampled 2025–2026 reports describe phone/processor pairing or reconnection trouble in particular setups; they do not establish current prevalence or universal device incompatibility.
- A cluster of July 2025 reports describes failing to launch after an update. One report says reinstalling fixed its update problem; later-version performance is not established by those older reports.
