AudioStream - Bimodal Streaming

Made for Bimodal

Use a hearing aid on one of your ears? No problem! SONNET 2 is compatible with every brand and type of hearing aid because our implant systems mimic natural hearing. And if your hearing aid supports audio streaming, you can even stream sound to both your ears at the same time. All you need is AudioStream and a compatible smartphone.

Is my phone or tablet compatible with bimodal streaming with AudioStream?

AudioKey 2

Be In Control

Gone are the days of carrying around a remote control. With the new AudioKey 2 app, you can change settings on your SONNET 2 directly from your phone. Volume, mic sensitivity, program selection—all at the press of a button.

What’s more, AudioKey 2 also lets you see your individual hearing stats, such as how long you wear your SONNET 2 each day. And if you unexpectedly lose your processor, the "Find My Processor" function shows where you last used the app with your audio processor, so you can retrace your steps.
