As a gamer who also likes to listen to music, I wanted a nice 2.0 speaker set up that was compact but, nonetheless, quite powerful. I don't really have room for a subwoofer as my PC gaming tower is so huge and I need to get my legs under the desk as well! I'd had a rather bad experience with the Logitech Z10 USB speakers which only ever worked sporadically for me - they would pack up every time Windows updated and appear to have issues with 64 bit Vista, which I have.
So I researched these speakers and discovered that they weren't USB connected and could be plugged into either my soundcard or my onboard sound, and went for it. The sound is GREAT! Clear and rich sound both for gaming and music, and power a plenty! And oh joy, back to the normal dial/knob to adjust rather than the dodgy touch screen. The speakers are large-ish, but not obtrusively so, and I like the design of them. So simple to set up, just connect together, plug into mains and to your PC, power up and off they go!
If you are in the market for a good quality compact speaker set up, look no further, and they are a steal at the price Amazon are offering, so get them!
