Enjoy water with Aqua+

Being able to play in and around water is one of life's joys - that's why we designed the Cochlear™ Nucleus® Aqua+. The award winning Aqua+ transforms a compatible Nucleus Sound Processor into a completely waterproof solution1.

There's so much you can do with the Aqua+, including swimming in the pool, soaking in the bathtub, splashing at the beach, taking a walk in the rain or even enjoying water aerobics.

Waterproof your sound processor

The Aqua+ is a soft, flexible silicone sleeve that fits over your Nucleus 6 Sound Processor. When used with the Aqua+ Coil, it allows you to enjoy water activities where additional protection is needed.

Using the Aqua+ is easy

  1. Slip your sound processor into the silicon sleeve with the earhook removed and microphone protectors in place
  2. Place the special Aqua+ coil into your sound processor
  3. Close the bottom of the silicon sleeve securely
