So far I have only tried fiction. I have Bose headphones so I can pause the audio with a button on the headphones which is nice when I need to stop and go back over a paragraph. If I were reading non-fiction and there were charts or diagrams I imagine I would use that feature a lot.

It seems like when I was younger it was easier for me to get completely immersed in a book to the point where I wasn't really seeing the individual words anymore. I would enter a flow state where I would just see the contents of the book unfolding in my mind's eye. Listening to the audio while I read puts me back into that state very quickly and keeps me focused. I have only been doing this for a couple of weeks so it is still early days. It seems like I keep more of it in my mind and notice larger patterns and themes that unfold over many pages.
