Summary: I bought these to use in a classroom, and they simply weren't loud enough. People in the back couldn't hear very well. So if you're a teacher using them for this purpose, consider the size of your classroom before making the decision. I ended up having to buy speakers with a separate power source.
USB is for power only and there is a terrible wiring bundle with the standard 1/16" audio plug

Summary: I bought these as usb-powered speakers. Well, that's exactly what they are, USB is for power only and there is a terrible wiring bundle with the standard 1/16" audio plug, and two speaker cables crammed in the overmolded plastic at the usb connector.
Excerpt: I was really looking forward to having some speakers that sounded good. I read the reviews and they made them sound so much better than they turned out to be. The only honest and true statement was that they were magnetic and stuck to each other. The sound was not good!
Excerpt: We needed speakers for our laptop computer in order to watch Netflix. We tried other speakers but they didn't have the sound quality that we had hoped for. We purchased these speakers at Staples. They were recommended to us by one of the associates who assisted us in our decision.
Excerpt: These are small speakers and I was a little worried about the sound; however, they are actually really great with sound. The previous speakers I had were the same brand, but they were larger and had to be plugged in to an outlet and the computer to work.
Excerpt: These are great speakers with very good sound but I had to buy an extra part to make it work on my son's laptop since his audio jack wasn't working. I searched for USB speakers and these came up in the search. They are USB powered only!
