Summary: I returned these speakers because the sound was horrid! I could only turn the volume up halfway because anything beyond this would sound as if the tweeter was ripped and flapping. The speakers have a tinsel sound when playing music.
Summary: XP does not recognize the N400 wireless speakers. There seems to be both hardware and software problems. Every time you start the XP with the Creative speakers connected via USB, it takes few attempts to go through Control Panel and audio settings to get the sound come out of the speakers.
