Fred, this gave me an idea: can you hand your aids over to your audi, have them put the aids in their OWN ear (if need be, swap the dome you use with a “one-size-fits-all” silicone dome and then actually HEAR what the streaming is doing?
In the old days of analog aids, I recall my first audi hooking up my custom molded Starkeys to a device that looked like a stethescope. That way HE could test how my aids were working.
That said, my Marvel aids occasionally do that very same thing when in streaming mode with the phone: drift from stereo to mono. It’s typically only when the battery life is winding down tho.
