Before you rip into the mic, test that it works! It could save headaches later.
Most of these mics just screw together to allow for the occasional cleaning. Twist the top off and pull out the microphone-holding center piece. Cut the wires as long as you can so that there is enough slack that the wires don't break when the microphone is screwed back together. If there isn't enough you may need to extend them a few inches.
