Lapel microphone: a small microphone designed to be worn on a person's clothing.

A shotgun microphone is a highly directional microphone that must be pointed directly at its target sound source for proper recording.

an omnidirectional microphone is designed to pick up sound from all sides of the mic, meaning that a speaker can talk into the microphone from any direction and it will be able to capture the sound.

Unidirectional Microphones are microphones that only pick up sound with high gain from a specific side or direction of the microphone.

Windscreens and pop filters are used in conjunction with microphones to assist in reducing excessive pressures on a microphone's element.
