The Edifier R12U Black 2.0 USB Powered Speakers may appear small, but they produce a sound twice its size. Designed with a bass reflex port, anything you play is clear and rich. With the 3.5mm auxiliary input you can plug in your iPod, tablet, laptop or phone directly to the speaker to play your favorite music. The USB powered speaker is small enough to travel with you and boisterous enough to hear your videos loud and clear.
