We have a few clients who purchased these SK400 speaker sets, the general consensus is their all looks.
Most found the RGB, regardless of setting, annoying and/or distracting. The sound quality at low volume was okay, but it higher volumes suffered dramatically. Also, they work best from their own independent 2.4A wall wart, and not plugged into the PC, even though it states the max draw was 1A.
Our clients have found that the smaller/simpler. Logitech S120s seemingly produced better sound, as their not trying to hide themselves in a big box.

If you're looking for the same size, and even better sound, this has been our client's choice for the last 36 months
Cyber Acoustics CA-2014 multimedia desktop computer speakers
But if you're looking for outstanding sound, in the same price range, this has been a client go-to
