Why upgrade?

True wireless

Nothing comes between you and your sound processor for phone calls and streaming TV and conversations.


Small and discreet design

An ultra-compact design makes the Nucleus 6 the very smallest Nucleus Sound Processor available.2


Adapt to all
sound environments

SmartSound® iQ (SSiQ) technology3 uses dual microphones to zoom in on preferred sounds, such as speech, and filter out surrounding noise. In a multi-center study, upgrade patients demonstrated up to 77 percentage point improvement automatically with SmartSound iQ.4,5


Swim underwater

You can now swim underwater without cords and big enclosures. Immerse yourself in the highest water resistance rating available from Cochlear through the Nucleus® Aqua+.6
