Review: Good but not ground breaking - If you have a high end motherboard, you don't need this. Sound quality is marginally better on normal sound output devices. Higher end speakers/headphones/earphones may well see better improvement. The Software is easy to use but installing it and getting the device to be detected is a pain.
Review: Smaller than expected lol - The item works and looks great. Just way smaller in my hand than I thought lol
