Here’s another UFO gadget to go with all the rest of your alien themed gadgetry and there’s plenty of it out there. This 5V speaker has a 3.5mm audio plug that will work with your MP3 or MP4 player as well as CD players and even cellphones. The speaker itself measures 2.87 in x 2.87 in by 1.38 in. You can purchase the tiny UFO for $13.90 from Deal Extreme. Which really isn’t too bad of a price for a portable speaker.
