I always have a lot to read, but I usually don't have time. With audiobooks, that's no longer the case - I can now enjoy my favorite books while on the road, driving, or even cooking.
What I particularly like is the variety of audiobooks. They come in a wide variety of genres, from thrilling mysteries to romantic stories to inspirational non-fiction stories. The speakers also give the stories a very special atmosphere.
Another plus is relaxation. When I'm stressed, I just sit back and get carried away by the voice and the plot. It's almost like diving into another world and leaving everyday life behind.
