I tried and tried and keep trying with audio books. I could not and would not listen to them while driving. I cannot pay attention to anything other than traffic. I can't often even remember what song was on when I get to where I go. No way could I space out and listen to a story while behind the wheel. I don't drive long enough anyway to make that worth it.
At home, unless I sit down firmly and stare at a spot on the wall, or close my eyes, my mind goes off wandering. I tried to listen while doing chores around the house, would be perfect. But by the time I load the dishwasher I don't remember a thing that was said. Nothing.
Main issue though is that I read much much faster than a voice reading to me and speeding up is not an option, sounds like a chipmunk and takes away the story.
I just read for so long my brain processes reading in a certain way, I go into the story with my mind. Listening stays on the surface for me and like backround and I just can't get into the story. I stay to the side of it. If that makes sense. Just not enjoyable to me. I wish I could make them work and I guess I keep trying and trying and trying.
As to the phone reading, I just can't do it. Heck, I don't even enjoy reading from a tablet and my tablets have great screens. My eyes just don't do well on it. My phone is also smallish for reading, 4.5 screen I think. Even if I could afford a 6 inch monster, I am trying to imagine talking on something the size of my Fire6. I can't even.

I only read on my phone a few times while short waits in doctors office. But I can barely get into a few pages and very very slow. Anytime I know I'll sit somewhere longer, hospital, doctor, car place, I'll take my kindle (e-ink).
Of course it might be different if I was a youngster, with better eyes and having been born when portable devices to read on where common. I was a teenager in the 80's alas.
And every person and everyones eyes are different. Hey, as long as they are reading I guess it doesn't matter on what. For me though, I need e-ink, or whatever the technological equivalent might be one day.
E-ink was a savior for me. It let me read again. That is pretty priceless for a reader. I am afraid what happens when my eyes go down hill even more if I can never make audiobooks work for me. I'am popping Lutein like candy to keep them going.
