Focus on what's important
"As a primary school teacher having better hearing is very important because I need to be able to hear where students' questions are coming from and answer them straight away. The Kanso allows me to do that."
- Alison V, Cochlear™ Nucleus Kanso® recipient, Australia
Filter out background noise
Dual microphones work together to filter out background noise and provide better hearing performance in noise than a single microphone.2
Hear well in different environments
Capture every moment. Whether in a quiet room or outside on a windy day, the device will automatically adjust using SmartSound® iQ with SCAN technology.
Bring sound closer – no strings attached
Cochlear™ True Wireless™ technology helps free an adult or child (and their hands) to focus less on hearing and more on what's important for them.
Enjoy face-to-face conversations
Activate ForwardFocus~ in the Nucleus Smart App to decrease distracting noise coming from behind, so that they can better hear the person in front of them.4
Peace of mind for parents
"She can be whatever she wants to be, and find who it is that she is going to become. Phoebe does really well at school. She has awesome teachers. She's taken off."
- Cynthia S, mother of Phoebe, Cochlear™ Nucleus® recipient, USA
