The USB 2.1Channel (Virtual 7.1) sound adapter is a highly flexible audio interface

which can be used either with Desktop or Notebook systems. Bundled with Xear 3D sound

simulation software, it turns your stereo speaker or earphones into 2.1 channel

environment (Virtual 7.1 effect). No drivers required, just plug and play for instant

audio playback, also compatible with all major operation systems.
