Plug it in and it works! This has to be the easiest microphone to use I have ever seen. The lighted on - off switch is placed on the base and is easy to see and use. I prefer the voice activated settings instead of using a hot key or the switch on the microphone to talk. Because it sits on the desktop it can pickup vibrations from the equipment when its in the always on mode. I put a simple soft pad under it and the noise stopped. I would recommend this product to anyone needing a PC microphone.
