The Cochlear™ Nucleus® implant system features a range of options we designed to meet an individual's hearing needs and to provide them with high-quality hearing performance.

There are two main components of the Cochlear™ Nucleus® system: an internal implant and an external sound processor.

While hearing health professionals will help match suitable implants for hearing needs, there are a variety of sound processors to suit an adult or child's lifestyle and hearing preferences.

Adults and children can explore their options and learn more about the convenience of Cochlear’s exclusive wireless technology.

With the most reliable implants in the industry,1-3 adult's and children's hearing is in good hands.
