I listen to audiobooks quite a lot while driving. I installed an after market mp3/cd/radio in my old car-traded the car in & didn't want to go through the hassel of installing a new mp3 radio...yet. I ordered the Monster 300 hoping it would work well enough with my creative mp3 player so I would be able to listen to audiobooks. It works like a charm, probably would sound pretty good for music but I haven't tried it with any music yet. The volume on the radio needs to be cranked up a bit over what you would have it set for when listening to a cd or the radio. All in all it works better than I had expected & only cost about $25.
