Connect like never before

The Cochlear™ Nucleus® 7 Sound Processor is the only cochlear implant sound processor with built-in technology that lets adults and children stream sound directly from a compatible Apple or Android™ device* — without the need for any attachments to the sound processor.

This means that adults and children can stream their favourite movies, TV shows, music and more directly to their sound processor without sacrificing size, comfort or battery life.

Convenient control with the Nucleus Smart App

The Nucleus® Smart App is designed specifically for the Nucleus 7 Sound Processor to provide you with a convenient and easy way to tailor an adult or child's hearing to their personal preferences — all from their compatible Apple or Android smartphone* or Apple Watch®^.

With the Nucleus Smart App, adults and children can quickly and easily:

  • access personalised hearing information with the Hearing Tracker

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

  • get help finding the sound processor if it's misplaced

  • start wireless streaming to Cochlear™ True Wireless™ accessories

  • fine tune the hearing experience by adjusting Master Bass, Volume and Treble

  • set up notifications to alert if the coil is off.

To experience all the features of the Nucleus Smart App, download for free via the Apple App Store or the Google Play store.

Peace of mind with Find My Processor and Hearing Tracker

We all misplace things or forget where we put them. With the Nucleus Smart App, adults or children can locate a lost Nucleus 7 Sound Processor using the GPS functionality that tells them the last location the sound processor had contact with their compatible smartphone.

Another feature on the Nucleus Smart App is the Hearing Tracker. This feature provides you with direct access to important information such as time when the coil is off and the time in speech. For parents, this helps measure that their loved one is hearing, especially when they are not with them.

The Hearing Tracker information, along with the built-in data logging functionality of the sound processor, helps an audiologist troubleshoot and make adjustments.
