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.


Simple Streaming
Use the phone you like, and connect it to the audio processor you love. SONNET makes it easy to listen to your favorite music and enjoy phone calls with your loved ones in high-quality, true stereo. Just slide the AudioStream cover over your audio processor to enjoy direct wireless streaming from your smartphone or tablet.
