I connected my JBL creature speakers to the treo 600 and it plays music on ptunes and stories from audible. Question: is this bad? Am I risking harm to my treo 600? I'd like to listen to books on tape but not through my headphones but these speakers.

by the way, the altec lansing ipod speakers have an external jack to connect to mp3 players (i.e., treo 600). An alternative to the JBL creatures.
