I used to think so too! My listening comprehension is just sad.

But it works great for the "let it flow through you" approach. It feels like I retain nothing and have no idea what I've read. But if I just try to trust my brain and repeat back or explain the content, without feeling like I know it, the words that come out of my mouth are correct.

The key may be that I do this listening while running. Keep the body busy so I don't distract myself and let the mind wander with audio playing in like a guided meditation style.
