This product is used, but it's in almost new condition, having only been used for about an hour after purchase. Included accessories are two USB cables that can connect to gaming consoles (such as PlayStation and Nintendo Switch) and computers. No special software installation is required; it's easy to use just by plugging in the USB (plug-and-play compatible). The main features are the ability to flexibly mix game audio and voice chat audio, and to adjust the volume of each individually.
