The Music Mug Speaker is a desktop iPod speaker shaped like a mug. A musical mug. Hence the name. The speaker part is actually on the bottom and you plop your iPod or other inferior music device into the mug itself to hold it. You can carry around with you (but you’d look pretty stupid) if you want. The sound is probably as good as you would expect from a speaker with it’s output aimed directly at your desk instead of up or out. Just don’t fill the music mug up with an beverages, it’s not that type mug buddy.
