In my attempts to figure out why my microphone is buzzing, I have determined that it only actually buzzes when I put it in the position I need it in in order to record. If I tilt it back, or up, or to the side, the buzz stops.

I cannot figure out if this is because of some stress on the connection, or some external source of interference that must be directly behind me somewhere.

I swear to god my downstairs neighbor must have some kind of large-but-silent electronic device because nothing I do in this room changes the situation, but some days it just doesn't happen, and some days it does.
