poker books in general are not suited so much as an audio book. Ace On The River is quite good, because it is more of an biography with many little stories and doesn't so much discuss strategy and hands. HoH would be a horrible as audio book.
Phil Hellmuth's audio book is probably bad b/c i cannot listen to Phil's voice for a longer period of time, his voice just gets annoying. If you need help to fall asleep in the evening you should get David Sklansky to read his book
