The first is a lavaliere mic that clips to your lapel or collar. When wearing a lavaliere, speak conversationally with the same amount of volume and vocal projection you would use to address a small group. If you are speaking in any venue that is larger than an average sized classroom or conference room, I strongly suggest using a microphone to prevent vocal strain. There are two types of microphones you are likely to encounter.
