I have been searching for a decent RMS speaker for my Creative ZEN....the fact that this speaker is for ipods was not a problem, there is a jack after all and I would not have used it with the ipod in place anyway as I need to see the display and need to access it every 2 or 3 minutes.(I will use it in my job) I'd personally like a visual display of what the volume is (as using the creative the ability to do volume goes to the speaker only) and a bass/treble control would be nice as sometimes I have found some songs sound too bassy when at higher volumes. I have heard the ipod speaker, the bose, the IM7 altec lansing...and I know creative have a new docking speaker but RMS WAY too low for me sadly ....and of all these I have heard....this was the best.
