Mine started giving me problems yesterday too–right one is periodically shutting down (becoming an ear plug) or its volume drops to barely audible (no volume change on the app or buttons). Anybody got ideas why other than everything I’ve tried already: cleaning receiver, moving mold around in my ear to make sure vent isn’t blocked, visually checking for loose wire; re-pairing the aids’ connection. Trying to keep from having to send them back to the shop, if possible. Although they’re so new I’m surprised this is happening. So anyway, not updating any iPhone stuff until this gets straightened out. One thing at a time!
