I listen to audio books in two formats----buying the book in a CD set or an electronic copy from Audible that I play on an iPod or my Kindle. I like the CDs since I play them in my car on road trips. There are also inexpensive portable CD players at most retail stores like Walmart that are easy to use. I buy used CD books on eBay for under $10 because new ones cost $25-50.
The electronic version from Audible does require some basic computer skills to purchase and download plus the device to play them on like an iPod or Kindle is more expensive than a CD player, and Audible books can be pricey. If you happen to be an Amazon Prime member you can "borrow" one free Book a month for the Kindle.
