Listening is different and takes some adjustment. You need to keep pumping words into your ears until the pathways form, if you want to make that adjustment. It took me more than 3, that's for sure.

For a while I would lose focus or get sleepy, and don't remember much at all from the first few audiobooks I listened to. I relistened to some of them and it was almost like a new book, but I listen to so many more books now than I would ever have time to read. I listen when driving to places I know, but if I am following new directions I can't really focus on the book, so don't listen at those times. I listened to the entire Malazan Book of the Fallen, a notoriously large, complex, and layered series, and am actually surprised by how much I got out of it.

I didn't even want to get into audiobooks, I was against them, but I had a 3 free month trial, got the books and ignored them for years until I finally wanted to read one of them and didn't want to buy it since I already owned it. Now I listen to so many.

Also, get a library card and find out what apps they use, you can borrow audiobooks right to your phone, it is awesome.
