The Orengon Scientific speakers with transmitter has been one of the most reliable one we've tested so far. I recommend this one (instead of their other models) because it is a bit more universal with what you can use it with (not just ipods). You can use it for ipods, mp3's, stereo, and even the television. Of course we all love wireless. (Do you have a wired mess under the desk too? Mine is becoming unruly!) $112
