What's so great about it is that you can "read" so many more books than you ever thought possible. My Goodreads shelf has doubled in the amount of books I can get through in a year. That's because you can listen anywhere. You are not confined to places you can sit or lay down to read. Even then, ever try laying down to read a book? That's entirely uncomfortable.
I thought my Kindle would have helped me read books at the gym, but, no. While you don't have to worry about turning the pages, still bouncing up and down while running makes it too difficult to read. That is simply not the case when you get to listen to a book. You can immediately get lost in the story as soon as you put those headphones in.
Still have some doubts, well don't! You can start an Audible Free Trial today and get to try it out for a month. You even get a free book with it! Now you can feel confident you can get first-hand experience with it without the hassle.
