Stupid jack mics

(apologies if there's a related thread)

I currently only have 20 dollars to buy a new mic but all I'm getting are the ones that aren't usb mics is there any way I can fix the quality of them or something.


What I mean

The only think I can think of is to make sure the room you are recording in is quiet, the mic isn't clipping, and adjust the levels + use sound removal after you record. You might be able to finds some cheaper, decently working mics online ^__^"
From my experience at least, a mic's built the way it is... usually compressor mics are of better quality, but they're more expensive. So you can't really change what pitches it chooses to record (which can also very with temperature).
