I have the issue with podcasts since the upgrade to Watch OS 10 , to get them to play from my watch when I leave the iphone behind, ie going out for a run / or leaving the iphone in the car , I either have to turn the phone off, or quit the podcast app on my watch and restart it when away from the phone , to get it to play to my AirPod pros . If i start a downloaded podcast on my watch when near the phone, it seems to be playing from the phone rather than the watch and once i get out of range it stops, and I cant recover other than quitting the podcast app on the watch .
The op should re-phrase the question , the question he asked was which MacBook has the best speakers and battery yet people are recommending which they think will suit the ops needs best. Does he need a MacBook Pro. Probably not. But does the MacBook Pro have better speakers than the air. Absolutely.
Questions like this are a bit useless without context and an idea about what sort of budget they have. It’s like asking which car is the fastest and has the best mpg.
