Connect like never before

The Cochlear™ Nucleus® 7 and Kanso® 2 Sound Processors are cochlear implant sound processors with built-in technology that let you stream sound directly from a compatible Apple or Android™ device* — without the need for any attachments to the sound processor.

This means that you can stream your favourite movies, TV shows, music and more directly to your sound processor without sacrificing size or comfort.

Control settings with the Nucleus Smart App

The Nucleus® Smart app provides the ability to directly adjust the settings of the Nucleus 7 processor and ensure its operation from a compatible Apple or Android ™ device * or an Apple Watch^.

With the Nucleus Smart App, it is possible to:

  • Access personalised hearing information with the Hearing Tracker.

  • Quickly change programs or volume and check battery life without carrying a separate Remote Control.

  • Find a lost processor using the "Find my processor" feature.

  • Start wireless streaming to Cochlear True Wireless™ devices.

How Find My Processor and Hearing Tracker work

The Nucleus® Smart App may be used to locate a Nucleus® 7 or Kanso 2 Sound Processors by using GPS to define the last location of the sound processor using a compatible smartphone.

The Hearing Tracker may be used for information about when the coil is off and the time in speech.

An audiologist might be able to use Hearing Tracker information for troubleshooting or adjustments.
