SYNCHRONY for EAS

Featuring the latest technology and the softest electrode arrays in the industry, SYNCHRONY lets you hear the world in full colour.

SYNCHRONY EAS implant

The Full Spectrum of Sound

To hear your best with EAS, you need to have some natural hearing ability—even if it’s only some sounds. Your natural hearing will help you to hear the low tones, giving you the full spectrum of sound.

A good quality EAS system should be designed to preserve your natural hearing. A poorly-designed implant could damage your ear, putting your natural hearing ability at risk. That’s why it’s important to choose an implant that is designed to protect your ear, so that you can maintain your natural hearing and experience sounds as they were meant to be heard.

4

Flexible Compatibility

Benefit from the latest technology. SYNCHRONY is compatible with all our current EAS audio processors, giving you the flexibility to upgrade at any time.

SYNCHRONY EAS Triformance

Hear Naturally

SYNCHRONY is built to protect your ear, particularly the delicate structures of your cochlea. This way, you can keep more of your natural hearing ability once you have your implant, giving you optimal sound quality.

But how does SYNCHRONY protect your natural hearing? It’s all to do with the electrode array, the long thin part of the implant which is inserted into your cochlea. SYNCHRONY’s electrode array is super soft and flexible—in fact it is the softest in the industry. Because of this, it can be inserted very gently into your cochlea, preserving your natural hearing ability, and helping you to hear your best.

Easy MRI

Life has its unexpected bumps and falls, and most of us will have an MRI scan at some point in our lifetime. Thankfully, SYNCHRONY has outstanding MRI safety. Its specially-designed magnet can undergo even high-resolution MRIs at 3.0 Tesla, without having extra surgery** to remove the magnet.

That means you won’t have to have additional surgery just to get an MRI scan. There will be no hearing downtime—you can start hearing again straight after the scan. With SYNCHRONY, you can have hassle-free MRIs, without giving your implant a second thought.

Diamond-White

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.

Reliable Hearing

An EAS system should enable you to hear all day, every day, without any interruptions. Your implant should be of the highest quality, to give you reliable hearing for many years to come.

For this reason, we have spent decades developing the most reliable implants in the industry. Each MED-EL implant is handmade at our headquarters in Europe, to ensure it is of the high quality we expect. That way, you get the reliable hearing you expect.
