RØDE - NTG1

Then go with Scarlett Solo (practically unmatches in it's price range) and a shotgun mic such as this one: https://rode.com/en/microphones/shotgun/ntg1 Keep in mind. All of this is way overkill for voice chat compression. If you end up recording something professionally it'll be a bit better than the AUX one.

You could use a Rode NTG or Rode Videomic Go in that 1/8 port if you want a shotgun mic specifically, I believe they can be powered up through it. But using wireless lavs like Rode Wireless Go 2, Pro or Dji Mic II are also good options, so you can have good audio embed into your video, but also a 32 bit backup on the mic internal storage. If you want to use specifically shotguns with an XLR cable, it's better to record audio on a separate device like the Zoom H1 XLR and sync the audio in post production. If you intend to use multiple microphones simultaneously in the future, it's also a good idea to look into recorders with multiple ports.

We used to run Blue Yeti USB, and recently switched to Rode XLR. MASSIVE difference in audio quality, ease of operation, and customization. Not close
