Well sound wise they are truly amazing and crystal clear. The bass is even better and the fact that I actually needed new speakers makes it one of the best purchases for my PC. Got to say though I did not expect the subwoofer to be so big, not in a bad way mind it's just that my previous one was half the size of this. I now also have a soundcard on the way and that's when they should really shine. I read in some reviews that it's hard to connect the speakers to the wires, but I figured it out myself in under a minute without even reading a manual, so not sure what those fools are on about.
While I can't compare these to any other £50 2.1s all I can say is that the sound is simply amazing and for the price these are a steal.
