What the two inputs expect
A microphone puts out a tiny signal, so a mic input has a preamp that lifts it a long way. A line-level source, such as a mixer's output, a phone or a USB mixer's analog out, is already strong, so a line input lifts it very little.
On a desktop PC the pink jack is the mic input; the blue one, when there is one, is line in. Laptops and controllers usually have one combined headset jack (TRRS) with a mic input inside.
Plugged into the wrong one
A mic in a line input sounds very quiet and noisy even with every slider at maximum. A line source in a mic input sounds loud and crackly at the lowest setting. Neither is a broken mic.
Which one your setup uses
A headset mic on a 3.5 mm plug goes into a mic input or the combined headset jack. A USB mic skips both jacks: its preamp is inside the mic. An XLR mic goes into an audio interface's mic input, never a PC's line in. A mixer or GoXLR-style box sends line level, so it goes into a line input or connects over USB.
Put your choice into a working setup.
Check the exact platform, connection and required controls. Then measure the stand or arm position before adding mounting parts.
