To sell me one set of dodgy speakers may be regarded as a misfortune; to sell me two looks like carelessness. Great speakers but both sets suffered from the same problem. The volume kept going up and down erratically on its own, especially if I touched the volume wheel. Both sets I got were all right for a while but then they both went on the blink a short time later. I love the speakers, they really are good, nice and loud, good ergonomics but my confidence is so undermined I'm not sure I'd buy Creative speakers ever again. I don't normally write reviews or do feedback or anything but I was moved to do it this time because I am so upset.
