Electric Acoustic stimulation

If you have trouble hearing high-pitched sounds, discover how an Electric Acoustic Stimulation (EAS) system could give you the joys of sound.

What is EAS?

Are certain sounds easier to hear than others? Do people always sound as if they’re mumbling? Do you feel that your hearing aids are just not good enough?

If this sounds familiar, you may be missing out on hearing high-pitched sounds. When you cannot hear high-pitched sounds, you have a type of hearing loss known as high-frequency hearing loss. This type of hearing loss is common in both children and adults.

EAS is the combination of two technologies: cochlear implant technology for high-pitched sounds, and hearing aid technology for low-pitched sounds. By using two different technologies in one device, you can hear the full range of sounds, making it much easier to chat with friends, enjoy music, and communicate in everyday life.

SONNET 2 EAS Audio Processor

Don’t fit your life around an audio processor—choose a processor that fits your life! SONNET 2 EAS is the audio processor made for you. Choose how you’d like it to look. Choose how you’d like to connect to your phone and other devices. And choose to experience your best hearing, wherever you are.

Easy Listening

SONNET 2 EAS is built to give you your best hearing possible. Using a combination of both cochlear implant and hearing aid technology, SONNET 2 EAS makes the most of your unique natural hearing, so you can hear things as they were meant to sound. What’s more, with ASM 3.0 technology and FineHearing sound coding, SONNET 2 EAS makes sure you hear your best wherever you are.

Adaptive Intelligence

SONNET 2 EAS recognizes what kind of environment you’re in, and automatically adjusts settings to match. Best of all, you won’t even realize it’s happening.

Noise Reduction

From background noise in a café, to an unexpected dog bark, SONNET 2 EAS minimizes unnecessary noise, and so you can have the confidence to chat in any environment.

FineHearing

Hear the details with FineHearing sound coding technology. FineHearing lets you hear the world as it was meant to sound—from your favorite song to the voice of a loved one.

Simple Streaming

Use the phone you like, and connect it to the audio processor you love. SONNET 2 EAS 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.

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 EAS 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 EAS 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.
