  The Sandberg USB to Sound Link is a compact external USB sound card with connectors for both speakers and microphone. It allows you, for example, to connect an ordinary headset to your computer via a USB port without you having to disconnect any sound equipment already connected to the computer. This completely removes the need for complicated internal installations and gives you the freedom to move your external sound card around, for example between your desktop and laptop computers.
