Review on USB Powered Phission Computer Speakers - Upgrade, Black Glossy Stereo Speaker for Laptop Desktop PC - Plug and Play Option by Dan Husband

It has a bit of bass but is quite loud which is what I needed for a projector when watching movies in the backyard. It was a little tricky to get it working as you have to plug together the USB and another other cable that connects to the speaker. For the cheap price I paid I can't complain yet, I'll have to try this with my projector to watch movies. I gave it three stars because there is no on/off switch. You can't tell how high or low the volume is unless you're playing music and have to turn the knob to find out. It looks like it has been used and was returned, not in bad condition.
