The USB Tube Delight Audio device is a portable sound card that connects to your computer via USB 2.0, completely plug-and-play. From there you can plug in your speakers, headphones, microphones etc. via the 3.5mm jack and enjoy some sound! As a nice touch, 2 little USB adapters are provided, depending on whether you want your tube to stick out of your computer, or perpendicular to it.
