A personal audio equipment provided with an air vent unit and a noise cancellation function, comprising: a sound reproduction unit in a form modified to have an air vent unit that may partly open an ear canal; a speaker cover unit; the air vent unit; a noise cancellation unit; and a sound wave sensor. Due to having the air vent unit penetrating the center of the audio equipment, the personal audio equipment provided with an air vent unit and a noise cancellation function is capable of discharging moisture, easily sensing outside sounds when not in use, effectively blocking the outside sounds by automatically operating the noise cancellation function during a phone conversation, and sensing sound waves, such as alert or horn sounds that require a user's attention, to thereby block the noise cancellation function when necessary.
