SONNET Audio Processor

Hear the Difference

Any audio processor can give you sound. We want to give you more—that’s why our audio processors are powered by Triformance technology.

With a more natural sound quality that no other cochlear implant system can match, you can enjoy richer music and more natural speech. You’re choosing to hear, so why not choose to hear your best?

Sound on the Go

You’re adaptable. Your processor should be, too. With Automatic Sound Management 2.0 (ASM 2.0), SONNET adapts to your environment without frequent setting changes. Come wind, come crowds, you can focus on the sounds around you rather than the programmes in your processor.

SONNET Cochlear Implant Processor

Microphone Directionality focuses your hearing by using two microphones to sharpen the sounds in front of you. This gives you better listening, especially in noisy settings.

Wind Noise Reduction minimises continuous wind noise, making it easier to hear in outdoor settings. The wind noise reduction can be adjusted for your specific needs.

Automatic Volume Control continuously monitors your environment and seamlessly adjusts volume levels to ensure every sound is heard clearly and comfortably.

SONNET Phone Connectivity

Never Miss a Moment

Sometimes it can be hard to hear your best. For optimal hearing in challenging environments, the Roger™ 21 and wireless microphones from Phonak can be used with SONNET to easily connect to your phone, TV, and other devices. SONNET's flexible connectivity options mean you can connect however it best suits you.

No Interruptions            

We don’t like interruptions any more than you do. With that in mind, we’ve designed a processor with up to 60 hours of battery life, giving you days of uninterrupted listening without any compromise in sound quality.

Alternatively, use SONNET's specially-designed Rechargeable Batteries and power your processor the easy way.

Whether you hear the spring of the diving board or the siren song of the surf, consider SONNET your swimming sidekick. Go ahead—get in the water. The sleek, reusable WaterWear cover makes SONNET completely waterproof in any kind of water.
