Altec Lansing’s Orbit USB Stereo. To call these peripherals speakers really do not understand. They are specifically designed for decent (but not extraordinary) to bring stereo sound to your laptop with a reasonable price. That may sound like not much, but if you've ever spent much time using your laptop for music and games you know the difference a great sound that really can play.
And the cool thing is that they do not require a separate power supply. Audio and juices flow through the USB cable. That means you do not have to go hunt for an open bus at the airport and plug only to find the battery is empty.
They got a little fancy with the design, not that I complain. When you're ready to store these things can turn them away together to a tube that fits snugly to almost all forms of laptop bags.
