Want to make a splash with your cochlear implant? In this article, we cover everything you need to know, from waterproof accessories to IP ratings. Let’s dive in.
Afterwork laps. Ocean dips. Paddling in the kiddie pool. Swimming has to be one of life’s greatest pleasures. And the good news? You can swim with a cochlear implant and still hear all the sounds around you. It’s just important to make sure your audio processor is waterproof before you jump in—read on to find out more.
P.S. The information on this page only covers MED-EL cochlear implants. If your CI is from another brand, it’s best to check directly with your cochlear implant team.
Cochlear implant systems have two parts. The implant itself is surgically implanted and sits below the skin. As soon as you have healed from surgery, you can go swimming with it.
But the external part of the system—the audio processor—might need some extra protection before you start swimming. This depends on which audio processor you have and the kind of swimming you’ll be doing.
Our latest-generation audio processors, RONDO 3 and SONNET 3, have an IP68 rating—similar to the ratings of top-range smartphones. That means they are waterproof for immersion in fresh water up to a maximum depth of 1 meter for 60 minutes. Accidental splashes, sweat, rain, swimming and water activities are no problem for SONNET 3 and RONDO 3.*
For salt or chlorinated water, as well as longer swimming sessions or diving, you’ll need to use the WaterWear accessory (see below).
* SONNET 3 and RONDO 3 have an IP68 rating: Waterproof for immersion in fresh water up to a maximum depth of 1 meter for 60 minutes. WaterWear should be used in chlorinated or salt water and when participating in prolonged, intense water activities. SONNET 3 EAS is water resistant and has an IP54 rating.
Our older audio processors, like RONDO 2 and SONNET 2, have a water-resistant design with an IP54 rating. This means that you can’t submerge them in water, but splashes are okay.
Good news though: You can still go swimming with your older audio processor. You just need to put on WaterWear first.
"Without the WaterWear equipment, Morgan wouldn’t be able to access sound in the water, and as Morgan enjoys water so much, this is such an incredible piece of equipment."

I am trying to get clarity on what kind of batteries to use if I am using Waterwear for white water rafting trip for eight days? I will not need to wear the Water wear all day but likely for 4 to 8 hours a day. I have read that zinc air batteries will not work and since we are without electricity, rechargeables are not an option. What are my other options?

Laine, thanks so much for sharing your question. If you are using a SONNET series audio processor, you can swap your zinc-air batteries with alkaline or silver-oxide ones: https://www.medel.com/hearing-solutions/accessories/waterwear Kind Regards
