Being able to adjust playback speed suits everyone's preferences – a thoughtful feature. With ListenBook, I've rediscovered my love for audiobooks. The binaural audio processing is a game-changer for comfortable, fatigue-free listening. No need for file conversion is a game-changer. Love using ListenBook on my iPhone. The statistics tracking feature is very useful. ListenBook helps me keep track of my listening time. Middle-of-the-road experience. The audiobook was fine—good narration, decent story—but it didn’t leave a lasting impression. If you’re looking for something low-commitment, this works.
