Hmm… Its Ceramic smart S9 and pin did come out. What is changed? on case or on receiver itself?
Its good to know how test receiver.
Anyway, its not receiver. Its either cold, or further ear damage on concert or right aid goin crazy. Mine “a” is lot softer on right - not in balance (low freq).
Ooo…never fit a Ceramic one so I don’t know if they are different…sorry.
If it’s not the reciever it could me the mic. I doubt it would be a sudden drop in hearing…you would notice it without the hearing aid in also…
Could be/most likely is moisture which may have caused something in the hearing aid to short out. If you turn it on tomorrow and it seems to be working and then cuts out again, 99% chance that it’s moisture.
