The Edifier R12U 2.0 USB Multimedia Speakers are here to make your browsing more enjoyable. The USB powered speaker is small enough to travel with you and boisterous enough to hear your videos louder and clearer. The R19U USB speakers produce a sound twice its size. Designed with a bass reflex port, anything you play through the Edifier speaker is clear and rich delivering a superior bass. With the 3.5mm auxiliary input, you can plug in your iPod, tablet, laptop or phone directly to the speaker to play your favourite music. The auxiliary input also means that you can connect with portable audio devices such as MP3 players.
