"Having the Kanso [Sound Processor] on my head and off the ear is a very relaxing and comfortable feeling. [My grandchildren] have started calling me because they see that I can use the phone, with or without the Phone Clip. I can stream my Bluetooth straight to my Kanso and it's just awesome. It's so real... the Kanso has truly brought me my music back."

- Sheiladawn, Cochlear™ Nucleus® System recipient

Peace of mind for parents
