Hello. I have been using the ReSound Quattro 9 with the fitting software (version 1.15) for seven years, but it is getting old and experiencing issues like battery drainage, so I plan to switch to the Vivia.
I understand that the Vivia requires the latest fitting software (version 2.3?), so I am reaching out for help. I plan to practice using the Quattro first. I already own a wireless Noahlink. Please help!
