CochlearTM Nucleus® Aqua+ is an accessory that transforms the Cochlear Nucleus 6 Sound Processor into the only waterproof behind-the-ear product for the cochlear implant market. While there are many things you can do with the Nucleus 6 Sound Processor around water, the Aqua+ lets you swim in and under water with confidence because of its increased water resistance rating (IP68). The Aqua+ is a waterproof silicone sleeve that fits over the sound processor. A waterproof coil, the Aqua+ Coil, is used to seal off the sleeve and complete the waterproof protection. The Aqua+ allows our customers to hear while participating in water activities. For some, this is the first time they have ever heard while in water!
