SONNET Audio Processor

Hear Your Best

  • Rechargeable batteries
SONNET Cochlear Implant Processor

Sound on the Go

You're adaptable. Your processor should be too. With Automatic Sound Management 2.0 (ASM 2.0), SONNET uses dual microphone technology to let you focus in on the conversation. Come wind, come crowds, you can focus on the sounds around you rather than constantly changing volume and settings.

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.

Dive Right In

The splash from a pool. The sweat on your brow. The sand on a beach. Life can get messy, and you shouldn’t have to choose between sound and the activities you love. And with the water-resistant, dust-resistant SONNET, you don’t have to.

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.
