Example Input: Excellent performance and sound quality. I have been using with an MP3 player to listen to audio books, which it does wonderfully. However, there are a couple of things that bother me about the unit, both when playing music on it itself as well as through my phone. First is the headphone jack. In order for the headphones jack inside unit to work, you need to open up the side door, or just slide your right thumb around the edge until you can slip in what seems like two wires.
Example Output:
