"Thanks to Cochlear, since upgrading from N6s to N7s my life has truly changed for the better in many ways! I find myself talking on the phone without any help, listening to music and understanding words more clearly, having more confidence in social gatherings, and so much more! I am happy to say that I am very proud, very blessed, and there is nothing that I cannot do!"
