Pros: Clip-on convenience.

Cons: I got this to clip onto the headboard for my SmartPhone to play ambient noise at night. Speakers pop, crack, cut out, and distort (imagine an amplifier with a blown transistor.) Had hoped sound quality would be fuller than my phone's external speaker, but it's not. In fact, I can't bear to use this thing at all!
Requires USB power so not for portable MP3 players or Smartphones, unless you use a wall-mounted AC/USB transformer.

Pros: These clip securely to your laptop or monitor, and look and feel high quality -not cheap at all. They sound great for a USB-only system, and deliver clean, clear sound -no humming or crackling. I like the blue LED on/off button, which has a firm click and should last a long time. It has a round volume control next to the power button, which does not emit any static when adjusted - nice. The speakers themselves are aluminum cones with rubber surrounds, and sit far enough apart to provide good stereo separation. The cords attached to the housing are USB for power, and a 3.5mm chrome jack, which goes to your sound card or onboard sound. These cords are relatively short, because this sytem is designed specifically for a laptop mount, but I purchased a 3.5mm extention cable and am using it on my primary PC monitor. This is a very nice looking, solid performing little speaker system, with great sound and volume. Buy it, if this is what you need.

Cons: No cons.

Other Thoughts: This speaker system fits my needs perfectly. It may be the right choice for you too.
