Cochlear Implants
SYNCHRONY Cochlear Implant System
A cochlear implant (CI) system helps to restore the sense of hearing for individuals with severe-to-profound sensorineural hearing loss. For individuals with this type of hearing loss, hearing aids provide little or no benefit.
A CI is the only medical device capable of replacing a sense. It works by bypassing non-functioning parts of the inner ear and providing electrical stimulation directly to nerve fibres in the cochlea. A CI system consists of two parts: an externally worn audio processor, which sits comfortably behind or off the ear, and an internal cochlear implant, which is surgically placed just under the skin.

FineHearing™
Can you hear the bass? Only our unique FineHearing sound coding technology gives you a richer perception of sound by including deep bass tones. With our FineHearing technology, SONNET provides a fuller, more natural perception of speech and music, especially with low-pitched bass sounds.
Structure Preservation
Our incredibly soft, flexible electrodes are designed to protect the delicate nerve cells of your inner ear. Structure Preservation provides a solid foundation for a more clear and accurate perception of sound. Protecting your cochlea enables your implant to deliver the best benefit, both now and in the future.
Complete Cochlear Coverage
To hear the most natural range of sounds, you'll need an implant electrode that's long enough to cover the whole cochlea. We offer the longest, most flexible electrodes available, making our electrodes the only choice for Complete Cochlear Coverage.
Sync With All Your Devices
With flexible connectivity options, both SONNET and RONDO can connect to nearly any external audio source or Assistive Listening Device (ALD), including neckloops and hearing induction loops. With the RogerTM 21 from Phonak*, SONNET can connect to a range of Roger wireless microphones.
