PURPOSE: An insert/circumaural type microphone is provided to increase the convenience of a user and a sound-focusing effect by locating the microphone in the inside of the user's ear or by making the microphone adhere closely to the entrance of the ear. CONSTITUTION: An insert type microphone part(42) is constituted where a connection jack(41) to connect a body to a musical instrument is constituted in one end and a projected part to be inserted into ears. A connection line for a signal transfer is formed between the connection jack and the insert type microphone part. The insert type microphone converts voice into an electrical signal by a convertor. If a vibration plate vibrates according to a sound wave, a coil moves in magnetic field and generates electrical signal. A circumaural microphone part(44) can be constituted which has a band capable of blocking an external noise.
