Hello Gail, Welcome to this forum!
When your 9050s chirped, was that before they played their usual startup tune, or after? Were you able to look at the tiny lights on the back of the hearing aids to see if they were blinking?
Did you try turning down the volume in the loud restaurant? Did it help your understanding?
When I first got my 9050s, I noticed that one ear was much louder than the other, for low frequency sounds that were streamed from my phone. The problem was that the hearing aid fitter selected an incorrect type of dome for one ear. That made the software program more amplification for that ear. Since you are not streaming to your 9050s, I don’t think that is your exact problem, but it is probably good for the provider to check the dome settings. (The challenge here is how to suggest this to your provider without sounding rude…)
