I can't put books on while I'm doing other things and take anything in. I will listen on walks or in the car (passenger) as I can focus on the words that I am listening to but the second my attention is on something else, it loses me.

I also have to pick the narrator carefully as I will tune out different people.

Books I have read before, and have a good narrator, will be used to go to sleep to.

It doesn't mean they aren't for you, necessarily, just that you need to be more selective in when you are listening to them and if it is background noise or something you are actively listening to.
