Yeah IDK if I'm just way worse at focusing on spoken words while doing other things than most people or what, but I can't get into podcasts or audio books at all. If I do other things while listening I miss so much that I have no idea what's going on, and even the supposedly very good ones are so dull that if I'm going to spend focused time consuming them I'd rather read, or watch something, or listen closely to some good music, or almost anything else.

I guess maybe if I got back into running they'd be good for that. Can't think of when else I could possibly use them.

I've found it extremely dependent on fine differences in the primary thing I'm doing. e.g. I have no problem following if I'm going on an uneventful or familiar drive, but will automatically tune it out if I don't know where I'm going.

This is why I find more casual listening like a podcast good. Listening to a book you can really hamper understanding of the later parts of it with low retention of easier parts. A lot of podcasts don’t really require your full attention at all times to understand later parts.

i've been listening to audiobooks since 2013 and i remember 99% of everything i listened. YMMV, but at least for me, it was a thing i had to "learn" -- as in, listen and pay attention while doing a boring task.
