I have had an SM7B with a Focusrite Scarlett interface for years. It works great; I can only recommend it. The SM7B definitely needs an interface because very little level comes out of the mic. Even with an interface, you're at the lower level.

I took this combo. You need a small mixer for the microphone. You also need a jack cable and a stand.

This is absolutely necessary with an SM7B but if you want a Shure without a mixer etc. I would recommend the Shure MV7. You can connect it directly to the computer via USB.
