I am a new user of the KS9. I have a problem.
When I use the hands-free phone feature I am getting a lot of static on incoming voices. This is not a problem, since when there is no sound on the other end there is no static. As soon as the person on the other end starts talking, there is static imbedded in the voice. There is no such static when the person on the other is listening to my voice.
I had a brief session today with the HA fitter. This fitter wears the same aid as me, and had the same sort of problem. He corrected his problem by changing a setting in the software. When he checked, he found that mine was already set correctly.
He turned down the streaming bass level, and it seemed to help when we tried it out at the store, so we thought that the problem was that the bass power was overrunning the receiver amplifier and driving it into saturation.
When I got home and took the first call, the problem was obviously still there. This has to be a common problem, and there has to be a solution - Phonak would not release an aid with this problem. The problem is not a Bluetooth distance problem, as I can put the phone as close to the HA as I want and there is no change.
Suggestions, other than going back to Costco for another try?
