Bimodal Streaming
with MED-EL
Our bimodal streaming system lets you stream sound from a compatible smartphone to both your hearing aid and your cochlear implant at the same time. Powered by an exclusive bimodal streaming partnership between MED-EL and Starkey, DualSync technology enables simultaneous streaming from Apple® devices to a MED-EL audio processor and Starkey hearing aid.
To learn more about how to stream with your Apple or Android device, please click below.

Bimodal Streaming for Apple
Stream sound directly from your iOS device to your MED-EL audio processor and a Starkey Edge AI or Starkey Genesis AI hearing aid.
DualSync is available with the SONNET 3 audio processor as well as via AudioStream for SONNET, SONNET 2 or RONDO 3. Click here for an up-to-date list of compatible devices and hearing aids.
How Does it Work?
For those who wear a MED-EL audio processor on one side and a Starkey hearing aid on the other, DualSync technology allows Apple devices to recognize both hearing devices as a pair for an effortless streaming experience.
To set up bimodal streaming on your iPhone, follow these basic steps:

1
Pair
Pair the hearing aid via the accessibility menu in iPhone settings.
If SONNET 3 or AudioStream is paired to the Apple device, forget it via the Accessibility Menu in Settings. If MyStarkey app is installed, completely close (i.e. terminate) or uninstall the MyStarkey app before bimodal configuration. The app may be reopened or installed after configuration is complete.
2
Configure
Open the AudioKey 3 app and select connectivity options then follow the configuration steps in the app.
3
Stream
Stream your favorite audio to both devices simultaneously!

Bimodal Streaming for Android
Stream sound directly from your Android device to your MED-EL audio processor and a hearing aid equipped with Audio Streaming for Hearing Aids (ASHA) technology.
Bimodal streaming with Android is available with the SONNET 3 audio processor as well as via AudioStream for SONNET, SONNET 2 or RONDO 3. Click here for an up-to-date list of compatible devices and hearing aids.
How Does it Work?
Many smartphones with Android 12 or later support “Combined Audio Device Routing” which allows the phone to stream to multiple compatible audio devices at the same time. Compatible devices include SONNET 3 and AudioStream, as well as any hearing aid that supports the Audio Streaming for Hearing Aids (ASHA) Bluetooth® protocol.
To set up bimodal streaming on your compatible Android phone, follow these basic steps:
1
Configure
Configure and pair your SONNET 3 or AudioStream within the AudioKey 3 app. Be sure to assign it to the correct ear.
2
Pair
Pair your hearing aid within the phone’s Bluetooth settings. Again, be sure to assign it to the correct ear.
3
