Hi. I was trying to share audio with my husband who also has AirPods Pro. I have a better data signal when travelling. The trouble is, his audio was really quiet and I couldn't figure out how to change the volume on his AirPods only. This is something I have always had trouble with unwounded if maybe I just don't know what I'm doing? Is there a trick to this? How do I get to his AirPods alone?
