Great news. Kanso® 2 is here!

Cochlear™ Nucleus® Kanso® 2 combines direct connectivity from your smartphone and hearing performance in a simple design

We are excited to announce the launch of the world’s smallest1 and most advanced2,3,4,5 off-the-ear cochlear implant sound processor – the new Cochlear™ Nucleus® Kanso® 2 Sound Processor. Combining the benefits of a powerful6, integrated rechargeable battery, smartphone compatibility and direct streaming*, the Kanso 2 Sound Processor is simple to use7 and is designed to easily integrate into an individual’s lifestyle.

Connect with what you love

Connect to the experiences and people you love with the new Kanso 2 Sound Processor. You can stream music, calls and entertainment directly from a compatible Apple or Android™ device*.  

You can also control your Kanso 2 Sound Processor or manage your hearing experience by using the Nucleus Smart App**. With the Smart App, you can personalise your hearing settings, check your progress with the Hearing Tracker or help find a lost sound processor.

I could talk on the phone and not have any extra devices on me, and it’s called freedom. True independence.

Focus on what’s important 

The Kanso 2 Sound Processor features our latest and most advanced technology1,2,3,4 to help you experience clearer sound, even in challenging environments2.

  • Our dual-microphone and Smartsound® iQ with SCAN technologies automatically adjust to your environment4 and helps you focus on the sounds you want to hear, like conversations, music and more.
  • In addition to the automatic SCAN features, you can also activate ForwardFocus*** in the Nucleus Smart App. Designed to enhance face-to-face conversations in particularly challenging environments, it reduces distracting noise from behind you, so you can better hear the person in front of you.2

It does help in my meetings. It helps in a restaurant setting. It cuts the background noise from around you so you’re focusing on what’s right in front of you. So that’s a pretty neat feature.

Designed for active lifestyles

Whether you’re working out or playing about, your new Kanso 2 Sound Processor is easy to use7 with its unique button-free control and automatic on/off features†.

With a dust and water-resistant construction, you don’t need to worry about being caught in the rain (certified IP68)^. Add the security of Cochlear Aqua+^ and your Kanso 2 Sound Processor becomes waterproof with the highest water resistance rating (IP68)^ for any off-the-ear cochlear implant sound processor1,8, so you can surf, snorkel or swim in salt, fresh and chlorinated water.

If I were to switch from a Nucleus 6 or Nucleus 7 to a Kanso, I would recommend to people, especially active people, that maybe [an off-the-ear sound processor] makes sense for them.
