An Important Decision
It’s important to choose the right audio processor, but it’s even more important to choose the right implant. Why? Because it’s the implant that most influences how well you hear.
SYNCHRONY 2 uses advanced coding strategies, designed to give you the closest to natural hearing of any CI system. This helps you hear the high and low tones, and the fine details of both everyday conversations and your favorite songs.
The Ideal Electrode
EAS is designed for people who can still hear some low-frequency sounds. Your EAS system uses cochlear implant technology to complement this natural “residual” hearing, helping you to hear better overall.
During surgery, your surgeon will try to preserve as much of your residual hearing as possible as this gives you better hearing with EAS. To help them with this, SYNCHRONY 2 only uses very soft and flexible electrodes. These have been specially developed to protect your cochlea during surgery, so you can keep as much of your residual hearing as possible, and hear your best with EAS.
An Easy Surgery
No one likes having surgery. Thankfully, our SYNCHRONY implants*** are not only the smallest and lightest titanium implants available, but SYNCHRONY 2 has also been designed to make your surgery as simple as possible. After an easy surgery, you can get back on your feet, and start enjoying the next stage of your hearing journey.
Made For MRI
You never know what life will bring, and statistically every one of us will need an MRI at some point in our lives. With some implants, this can mean extra surgery to remove the magnet in your implant, plus time without your audio processor as you recover from the surgery.
But not with SYNCHRONY 2. It contains a revolutionary kind of magnet that allows you to have MRIs of up to 3.0 Tesla without magnet removal surgery.* In fact, the way you have an MRI is no different with or without a hearing implant.
Great Protection. Guaranteed.
Because of our long and positive experience with MRIs and cochlear implants, we offer a life-long MRI guarantee. We promise to replace your implant in the very unlikely event that it’s damaged during an MRI scan.
This life-long MRI guarantee for cochlear implants is the first and only to be offered by any company and covers all MED-EL cochlear implants from as far back as 1994. So you can feel confident about any future MRI scans.
The Reliable Choice
Your implant will be with you for many years to come, so it should be reliable enough to provide you with years of use.
Like all MED-EL implants, SYNCHRONY 2 has been crafted to the highest standards. Each part is designed and tested for maximum reliability, before being manufactured in our European headquarters. And every implant has to pass our first-class quality inspection before arriving at your clinic.
All of this means you can expect the highest levels of reliability from your new SYNCHRONY 2.
Built For Everyday
Light and comfortable to wear, SONNET 2 EAS is your ideal audio processor. Its water-resistant design makes it practical for every day, and there are plenty of ways to make SONNET 2 match your personal style.
What’s more, with dual microphone technology, SONNET 2 EAS gives you your best hearing wherever you are.

* Unless required for diagnostic reasons.
** SYNCHRONY 2 has a self-aligning magnet, so there’s no painful magnetic pulling on the implant during an MRI scan.
*** MED-EL's SYNCHRONY implants include SYNCHRONY, SYNCHRONY PIN, SYNCHRONY
2, and SYNCHRONY 2 PIN.
**** Whereby “free” means “not made with latex” according to current FDA guidance.
***** It has been demonstrated that no known hazards exist in specified MRI environments under conditions as described in the SYNCHRONY 2 cochlear implant product labeling. The SYNCHRONY 2 cochlear implant is MR conditional. Recipients with
