I understand the Roger Select IN is specially made to integrate seamlessly with Phonak Marvel aids. Does that mean they also are integrated with Costco KS9s?
From my understanding, yes. However you can’t buy from Costco and they are not going to help you set it up.
A bent paper-clip is all that is required for set-up.
For connecting, yes.
For tweaking the roger streaming program, you need your fitter if default settings aren’t working for you.
