I will admit I was a little hesitant to purchase these Genius speakers, as the price seemed quite low, but I decided to give them a try, mainly because of their compact size. I plugged them into my Laptop USB and fired up some music, WOW!!!! For such small compact speakers, the sound output and volume is really great, I was pleasantly surprised. I would highly recommend them to anyone, especially if you are like me, you do not have a lot of work space on your desk.
