My son got this speaker last week. It sounds good, it is pretty loud. The only thing I would say against it is that it is kind of bass heavy. I'm not sure you would want that with strictly audio books. He had one he had picked up at Radio Shack when they were going out of business here. It is much less bass heavy so he gave it to his dad to listen to baseball games on. Hubby says that they sound better to him without so much bass. I'm not sure if audio books correlate or not.
