The four main types of microphones are dynamic microphones, condenser mics, ribbon mics, and USB.Dynamic microphones are the most common type, and are typically used for live performances.A Condenser mic is more sensitive than a dynamic mic and are often used for recording.Ribbon microphones are similar to condenser mics, but have a lower output level.USB microphones can be used with computers and are often used for podcasting or Skype calls.
