The first time I used a Logitech USB microphone like this was on a Karaoke Revolution game we bought a few years ago. I liked the simplicity of the mic and decided to plug it into my computer for some online karaoke (I know - I have a karaoke problem!) and it was a snap to set up and use.
When my son was looking for a vocal-quality microphone, I bought him this one as a birthday gift, and he's enjoying it thoroughly. It has the same, great Logitech quality we're all familiar with, plus it's plug 'n play, which takes the hassle out of putting it to work right away on a PC or other USB-enabled device!
