This is a condenser microphone that connects via USB and is ready to use. It's a set including the microphone, arm, shock mount, pop filter, and USB cable. However, the pop filter in the third image has a broken part for attachment (see photo 7). Other than that, it has some signs of use, but I think it's in good condition. I believe I have the box and instruction manual somewhere. If you'd like them, please let me know in the comments and I'll look for them.
