For some patients, the ability to use their cochlear implants while being exposed to water is extremely important. There are several waterproof options for cochlear implants, but it’s necessary to understand exactly what “waterproof” means.

There are three levels of water resistance when it comes to hearing aids and cochlear implants:

Waterresistant: able to resist the penetration of water to some degree, but not entirely. 

Water-repellent: not easily penetrated by water, especially as a result of being treated with a surface coating to repel water. 

Waterproof: will not be damaged by water (IP68).

Here is a chart explaining how IP classifications work. An IP Rating Chart can be very useful for understanding how waterproof a device is.

Med El WaterWearSonnet or Opus 2 WaterWear Included in the initial kit 1pk comes with three covers and seals (9 uses) Behind the ear (BTE) is $50.00 per pack and you need to use a rechargeable battery or Alkaline LR44 or silver oxide SR44 as the WaterWear is airtight and the zinc-air batteries will not last. The battery life is 8-10 hours.

Sonnet has an IP54 rating, so it can be splashed with water but cannot be submerged. The other processors do not have an IP rating, therefore, they are not water resistant.

This simple casing provides an effective and inexpensive solution to protect your cochlear implants. The processor and the microphone are both inserted into the case and it is ready for use. Watch this video on how to use WaterWear with Sonnet.

Rondo alone is not water resistant. WaterWear is a water resisting, reusable covering for your Rondo. It can be used in fresh, salt, and chlorinated water. WaterWear can be used 3 times.
