Just think how much bible you could read instead.
I read books for classes but very few of my text books are available on audible.com or I would listen to them when at the gym or doing tasks. So listening to books that I can find on the same subject of my classes I find very productive.
As to devotional bible study, I am currently studying 2 Peter. I will read 2 Peter several times over asking the Holy Spirit to illuminate me and depending on Him to give me the intended interpretation.
Then I will also read several commentaries from good writers who believed in the verbal inspiration of the Bible and are or were well respected scholars who know more than me. Sometimes I will read things I am not in agreement with but that is actually fairly rare.
Most of the time the commentaries I read will be saying the same thing as I understood it but will also give me much more than I noticed when I read it. Like background information, timelines, and most importantly other scriptures from other parts of the bible that contribute to the subject. This shortens my learning curve by decades if I relied only on my on bible reading.
I know this is painfully obvious but it astounds me how many people insist on wallowing in their own ignorance while a whole universe of biblical education is available to them for free. They pride themselves in being stupid. "I never read good bible reference books" they say. And you bite your tongue resisting the urge to say "It shows"
