SONNET 3: Tools and Tips for Your Patients

Our latest cochlear implant audio processor, SONNET 3, started shipping to clinics worldwide last year and thousands of recipients are now enjoying closest to natural hearing with our most advanced behind-the-ear processor. To help them get the most out of its innovative features—from integrated direct streaming to a touch key—here are some tools and tips to share with them.

New Handy Features on AudioKey 3

The AudioKey 3 app for RONDO 3 and SONNET series audio processors lets users control their audio processor settings, view detailed statistics, and locate lost audio processors. The latest update (Version 3.0.2), released in February 2025, has two new features aimed especially at SONNET 3 users:

1.     Audio Processor Push Notifications for SONNET 3

These audio processor push notifications can help your patients stay in the loop with a new feature that sends notifications directly to their phone. AudioKey 3 will notify them if their SONNET 3 coil has disconnected or if their battery is low.

You can activate this new feature for your patients in the latest version of our MAESTRO fitting software. This handy guide on our LinkedIn page shows you how.

2.     Activate SONNET 3’s Standby Mode

This new feature lets your patients put their SONNET 3 into standby mode directly from their AudioKey 3 app.

To use both these features, your patients will need to update to the latest version of AudioKey 3 in their phones’ app store.

We’ve created a series of hands-on videos for AudioKey 3 to help your patients familiarize themselves with how to use the app.

Here’s the link to the entire series of AudioKey 3 hands-on videos.
