I find that longer content works better for me when trying to understand important concepts. I generally need repetition and context (why is this a valuable concept? how'd you get here?). While it's quicker to digest bite sized audio, I tend to forget the takeaway easily.

Have found these links to be helpful in understanding the concepts here:
