Went back for my follow-up this week. We programmed my aides back to the original setting. I had complained last time about pitch and tinny sounds, so we lowered something. Then I immediately realized I lost the clarity I had before. So now, I'm back at the original setting, and today was a great test at my vehicle service appt. I heard everything said to me, and also had to sit inside my car while we went over alot of the technology devices and set some apps. Thank God, I heard the guy explain everything.
