I have a Rode X Streamer X as my audio interface.

Largely because I already own a good camcorder in a Canon XA10 that I can connect via its HDMI port. Secondly, so I can pre-program the soundboard with some fun effects.

I use their PodMic

On a recommendation of a friend over the Shure microphones I was used to at SiriusXM as these are a bit cheaper and since I have a board to plug it in I do not need to spend more for USB. It is very similar to Shure and is actually a better fit for a fast talker like myself and I like the uniformness of it.

Other gear? Otherwise I just have an Amazon XLR cable to connect the mic to the board, an arm mount I found on Amazon that works with my existing desk and an Amazon HDMI C cable that works with my camcorder (not to be confused with USB C).
