For a wired microphone, make sure you have proper cable management. Any kind of wire pull can damage both your internal and external microphone wires over time, making the microphone useless.
Do not unplug the microphone while the power cable is switched on if it is a condenser microphone. To disconnect your microphone, wait 30 seconds after the power cable has been unplugged. Then, you can safely unplug the microphone.
