Cochlear™ Nucleus® 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 the Nucleus 6 and 5 Sound Processors into a completely waterproof behind-the-ear solution.

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.

Featuring a water protection rating of IP68, the Aqua+ gives you the ability to swim with your sound processor without the need for any cumbersome cables, cases or a special sound processor specifically for water activities.

Special features of the Aqua+

  • Sits comfortably on the ear
  • Designed for use in salt, fresh and chlorinated water
  • Can be submerged under 3 metres of water for up to 2 hours
  • Comes with a safety line for added security
  • Remote Assistants work with the Nucleus Aqua+, so you can always have control over your or your child's hearing


“It’s awesome”

The first time ten year old Ben was able to hear in the water using the Aqua+ was an emotional experience for his mum Karen. Watch the video to hear about their experience with the Aqua+.
