Aha, didn't catch that. So that answers one of my questions. Seems it's not a content download then but a stream.The only problem is that you need to have wifi on. It doesn't work when is off.
Apple should just buy Endel at this point 🫣 I use that for stuff like this. Fall a sleep with it every night. Does a great great job. Well except for recently my 2019 Airpods Pro active noise cancelation starts giving me crackles and whit noise way way more often. So.I'd be drifting off asleep and then my left earbud will burst some loud white (or is it pink?) noise continuously ...FML.. guess this year I finally have to get the Airpods Pro 2 then. It's shameful what happend to the ver 1 users with these issues.
