Summary: Purchased three sets for the office and they all work fine. My set makes a low amplitude, high frequency sound just on the edge of my hearing, and it's really irritating. However, the computer's sound card could be at fault and not the speakers, because every set of headphones I've plugged into this computer have also picked up some form of interference.
Summary: I was looking for a cheap set to reduce power usage at my house, these fit the bill but there are down sides. They were everything I wanted but they have very poor shielding, it picks up heavy interference from my monitor (out of all things?? Maybe that is normal). It's noticeable enough to where I will most likely take these to work and buy other speakers. Overall not bad though.
Summary: these speakers look good but the power rating is not high at all. I have seen cheaper speakers with power rating of 8 watts. If genius puts out 4 or 5 watts for a nominal increase in price it would be a good deal.
