FIFINE - AmpliGame AM8

Fifine Am8 - affordable, great sound, easy setup, xlr AND USB connections for easier upgrades, dynamic (better off axis noise rejection, will lessen room noise). There are a lot of good microphones, but they might take more to tame for your situation.

So I'd recommend getting a good external mic. It's funny because I'm actually a mic reviewer too. I recommend the Fifine AM8 or RODE Videomic Go 2.

As someone who uses absolutely no headphones and has no speakers (only the audio from my monitor playing) i use this mic from amazon # FIFINE USB/XLR Dynamic Microphone for Podcast Recording, PC Computer Gaming Streaming Mic with RGB Light, Mute Button, Headphones Jack, Desktop Stand, Vocal Mic for Singing YouTube-AmpliGame AM8

If you are gaming, then get a dynamic mic as it is far better at not picking up typing noise or a washing machine. There is a reason basically all streamers and podcasters use a dynamic mic instead of a condenser one. Good budget ones are the audio technical ATR 2100x, Samsung Q2U, and Fifine K688 or AM8. I recommend listening to a youtube video to see what one you like the best.

I was super impressed with the quality of the fifine am8. The stand isn't great so you'll probably want a mic arm as well, but otherwise it is solid. The face cam neo is a pretty good facecam, although lighting is often the biggest change maker for cameras. Getting something like an Elgato keylight Neo or a neewer/gvm light panel can make a huge difference

I'd get the Fifine AM8T - it comes with a boom arm and a USB cable. It's $50USD on Amazon, and it's plenty good enough for Twitch.

It's hit and miss. With budget gear, consistency in quality is not assured. Expensive gear has duds as well, but they seem to be less often. Customer support & replacement policies for more expensive gear are often better. You can get a budget USB mic that will last years, but the odds aren't that great. The only Fifine mic I recommend is an XLR mic, and that's for bargain basement budgets. When it comes to most audio gear, the adage "buy once, cry once" is the best way to approach things. With low-quality equipment you can end up spending more in the long run, due to multiple replacements.
