Compact and Fully Integrated
What do you get when you combine traditional audio processor components such as the coil, control unit, and battery pack into one single unit? Fewer parts, no cable, and a feeling of freedom from wearing nothing behind the ear.
Just Put it On and Go!
Getting up in the morning and tuning in to a world of sound has never been easier. Attaching the one-piece RONDO is straightforward. Setting changes can be made on the fly with the FineTuner remote control.
Sound Makes the World Go Round
Sound connects you to the planet and the people who live on it. Hear it all thanks to signature MED-EL technologies and proven performance.
Nothing Behind the Ear
If you have a hearing loss, chances are that you've been wearing a behind-the-ear (BTE) hearing aid or audio processor for many years. Now, for the first time, RONDO delivers the freedom of an audio processor with room behind the ear.

Automatic Sound Management
Automatic Sound Management (ASM) enables recipients to hear their best, no matter the situation or level of background noise. ASM features Dual-Loop AGC and Automatic Volume Control for comfortable conversations in background noise. Automatic Volume Control ensures soft sounds are heard clearly and loud sounds are heard comfortably.

The integrated telecoil lets you connect wirelessly to a wide variety of audio-streaming systems. An available Mini Battery Pack provides a connection to standard 3-pin FM devices. The Mini Battery Pack with a 3.5 mm accessory cable enables direct audio input from any device with a headphone jack.
Enjoy an active lifestyle
With the MED-EL Sports Headband, there's no need to worry
about your audio processor shifting out of place or falling off.
Recipient Stories
Don, RONDO Recipient
"When my hearing loss bottomed out, I gave up my season tickets to the symphony. Now that I have my RONDO, I can enjoy music once again. Best of all it blends in so well, I can attend concerts without anyone even knowing I'm wearing it!"

"The day my RONDO got turned on, I called my family who live far away. It'd been a very long time since I was able to understand and converse with them over the phone. Hearing their voices so clearly, I knew right away that I'd made the right choice."
