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.

SYNCHRONY ST Implant Features

Unparalleled MRI Safety

You never know what life can bring. That's why the SYNCHRONY ST implant features an exceptionally secure implant magnet with the highest MRI safety of any cochlear implant.

Unlike any other cochlear implant, with SYNCHRONY ST there's no need to surgically remove the magnet for a high-resolution 3.0 Tesla MRI scan. The SYNCHRONY ST implant magnet can freely rotate and self-align inside of its housing, so it's not affected by the magnetic field of the MRI scan.

This also means there's no "tugging" on the implant, for more comfort and security during an MRI.

Outstanding Stability

Through all of life's bumps and bruises, the SYNCHRONY ST implant stays where it should be. The SYNCHRONY ST implant features an implant step for additional fixation of the implant for outstanding stability

The Right Choice for Any Cochlea

The electrode of a cochlear implant is the portion that is gently inserted into the cochlea. Our electrodes have the softest and most flexible electrode arrays to preserve delicate cochlear structures and protect your residual hearing.

There's a nearly endless variety of cochlear anatomies, so it's important that the electrode is individually tailored to your unique needs. We offer the widest selection of electrodes to ensure that the optimal solution can be chosen for any cochlea.

Powered by Triformance

Experience the fullest, richest range of sounds, perceive speech and music more naturally, and protect your hearing—all with Triformance.

To give you the most natural hearing possible, MED-EL cochlear implants are powered by Triformance, the combination of three key technologies: Complete Cochlear Coverage, FineHearing, and Structure Preservation.


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.
