It depends on what phone you haclve, iPhone or Android.
I have both the More1 and Real1 aids, i have the Samsung Galaxy S23 Android phone. I seldom use the companion app even though my aids have P1 general, P2 MyMusic, P3 Lecture, P4 t-coils, TV adapter, and remote Mix programs. I do have the connect clip, and remote control with my aids. Android phones don’t have the control panel like the iPhone does so i depend on the rocker control on my aids, the control from the connect clip or the remote control. Yes i have TV adapters to stream the TVs to my aids. But I very seldom have to make adjustments to my aids or the streaming volume from the TV.
If you have the iPhone i hape your aids stay connected to the phone because the iPhone control panel also controls your aids.
I left iPhone because the iPhone kept losing losing connection to my aidswhen i neeced to stream a phone call. With my Android phone i never miss calls because of dropped connect but the app does lose connection most specifically when connecting to the TV adapter.
