I'm an audiophile.
But one disadvantage of listening to a non-fiction audiobook, without having a print copy (paper-based or digital), too, is that you "never" get the footnotes/endnotes, and other ancillary stuff that the print-based book might contain.
There are exceptions to that rule. One that immediately comes to mind is The Great Courses courses, which generally, at least, include a PDF with each course, with the PDF including such things as transcripts, footnotes/endnotes, and outlines.
The audiobook version of Ken Ham's
The Lie (which refutes the theory of biological evolution), published by Master Books, is another exception. This may not be widely known, but they provide a separate digital pamphlet,
free, with footnotes/endnotes for the audiobook comprising most of the 27 pages of the pamphlet. There also are some additional goodies at the end.
