Simple Hearing

Hear your best and have conversations with confidence in any environment.



Microphone Directionality focuses your hearing by using two microphones to sharpen the sounds in front of you. This gives you better listening, especially in noisy settings.


Wind Noise Reduction minimizes continuous wind noise, making it easier to hear in outdoor settings. The wind noise reduction can be adjusted for your specific needs.


Automatic Volume Control continuously monitors your environment and seamlessly adjusts volume levels to ensure every sound is heard clearly and comfortably.

Compatible with All Hearing Aids

RONDO 3 is compatible with every brand and type of hearing aid because RONDO 3 and MED-EL cochlear implant systems mimic natural hearing.

What's more, RONDO 3 can even be easily adjusted for optimal hearing with any hearing aid—including the hearing aid you’re already wearing on the other ear now. Since you won’t need to buy a new hearing aid on the other side, you’ll save money and the trouble needed to readjust to a new one. Simply incredible!

Simple Handling

No cables, no changing batteries, no hassles. RONDO 3 is light, extremely slim and charges wirelessly. No worries if you forget to charge it overnight. You can still charge it on the go and continue using your RONDO 3 at the same time without any downtime! That will give you peace of mind!


Complete Convenience

Checking RONDO 3’s battery level is incredibly simple—either on your smartphone or by just pressing directly on the processor itself! It couldn’t be any more convenient.

Incredible Comfort

RONDO 3 was created for comfort and is barely visible on the head. It is worn completely off the ear, making RONDO 3 not only perfect for those with glasses but also incredibly comfortable for everyone.

Cut Costs and Waste

With an integrated rechargeable battery, you won’t use disposable batteries ever again. Save yourself time and money—and from the guilt of having to throw away all of those used batteries.

Wireless Charging

Power for Up to 24 Hours

RONDO 3’s integrated rechargeable lithium-ion battery can provide enough power for up to 24 hours—an entire day! Just charge it overnight while you sleep, and wake up to a full day of hearing.

Wireless Charging

Simply place it on the center of the inductive charging pad, and RONDO 3 will recharge automatically—no cables needed! Then you’re free to forget about it and get on with your day—or rest assured that RONDO 3 will be ready to go when you need it.

RONDO Swap Program

No need to wait for future technology. As of August 1, 2020, patients who choose a MED-EL cochlear implant with a RONDO 2 Audio Processor can exchange the RONDO 2 for RONDO 3 once it’s available.

Here’s how RONDO Swap works:

  • Choose a MED-EL SYNCHRONY Cochlear Implant system with a RONDO 2 Audio Processor. If your Patient Kit includes two processors, keep one RONDO 2 sealed for the swap.
  • When you receive your Patient Kit, you will be instructed to complete a simple, online pre-registration for RONDO Swap.
  • Once the RONDO 3 Audio Processor is available (expected later this year), MED-EL will contact you to complete the swap.
