Summary: I'm using them for listening in a bathroom/shower. I have them hooked up to an older smartphone that streams Pandora via wifi. I use the usb port on the speakers to keep the phone charged, everything is hidden behind or within the medicine cabinet. Speakers sound pretty good, usb port is a benefit for my use, only real gripe is the volume buttons rather than a volume knob.
Summary: Seriously, for $16 and free shipping on a refurbished item, what can you expect? These are not $145,000 Muon Speakers - these are speakers for your computer. I'm very pleased and, if you can find a used (from a commercial seller not a private party) with free shipping, that's the best route.
Summary: These speakers got the job done for private laptop viewing. If you plan on playing music in a larger room, forget about it. these are purely desktop speakers. Personally, i would rather have spend a little more money on some logitech speakers.
