A Decision for a Lifetime

While you’ll see your audio processor everyday, it’s actually the internal implant that is more important. Why? Because it’s the implant that is most responsible for sound quality. With an advanced implant, it’s easier to chat with friends and family, listen to your favorite music, or simply hear the birds singing outside.

And unlike your audio processor, which you can upgrade regularly, your implant will stay with you for many years. Therefore it’s important to choose a cochlear implant that will give you the best hearing both now, and in the future.

Great Protection. Guaranteed.

At MED-EL we don’t just offer you outstanding MRI safety. We even guarantee that your cochlear implant won't be 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.

Expect the Best

Reliability is a big topic when choosing your cochlear implant. You will have your implant for many years to come, and only the most durable and well-built implants will stand the test of time.

At MED-EL, we use our decades of experience to build cochlear implants of the highest quality. Each SYNCHRONY implant is handmade at our headquarters in Europe, and has to pass a series of strict quality inspections before being allowed to leave the building. It is our focus on quality that makes MED-EL the reliable choice for your cochlear implant.
