I don’t mean I’m listening to a lot of music on my new 12.9, but watching movies and TV is hugely improved over my old 6th generation, which only had a speaker on one side. I could hardly hear dialog unless I turned it way up, so I used AirPods a lot when watching YouTube and TV/movies. The sound on my new iPad is so much better that unless someone else is in the room, I don’t bother with AirPods anymore and hear everything fine. When the source is stereo, it’s very noticeable. It’s a huge upgrade that doesn’t get much attention.
