Pros: These USB speakers have crystal clear sound with no buzz or hum. The volume is plenty loud for normal use. They are perfect for listening to music while I work.

The USB drivers installed automatically (Windows XP).

There is not much bass, but there is more than I expected with small speakers. The bass is certainly better than earphones. Overall Review: I was hesitant to go with USB, but I am very happy I did. I wanted to be able to use these in a bedroom, I wanted zero noise with the computer off, and I did not want to have to remember to turn the speaker power off. The USB cord is about 4' and is about the same length as my keyboard and mouse. I like the power light that reads "DIGITAL".
