Summary: got this for my desktop PC for basic sound, I usually use a headset but wanted basic small speakers for general use. I thought these would suffice but the sound is tinny, and lackluster at best. The other reason I got these is because I wanted a small foot print and to not really see the speakers on that front they worked well.
Excerpt: This product is a great idea - a clip on USB powered speaker for your lap top. It amplifies acceptably, however it has a distracting hum. This hum is less noticeable when it is amplifying, rather when it is idle. I look forward to the next edition.
