I'm pretty sure it will vary a LOT from person to person... I remember what I see very well.. what I hear, not nearly as much. I say this as when I was commuting I'd listing to a lot of audio books and podcasts... I didn't retain much at all. But I can skim a written article and retain a lot more. Further still, if I literally copy something I see while writing it down, it's hard for me not to remember. That last bit got me through high school as I never did any homework, but always aced tests.

Everyone is definitely different in terms of how they learn best. That's not to say that listening to non-fiction is or isn't better for oneself than nothing, or even different forms of music may be different. There's nothing wrong with entertainment or factual knowledge... (See "Fat Electrician" on YouTube/Pepperbox for a lot of both.)
