A vehicle is provided to minimize the difference in left and right output intensity of a headrest speaker by adjusting an output intensity of based on the position of the passenger's ear. The headrest includes a left-side speaker provided on the left-side of the headrest of a seat inside the vehicle to output sound and a right-side speaker provided on the right-side of the headrest to output sound. A pressure sensor measures a force applied to the headrest and a controller adjusts the output intensity of the left speaker and the right speaker based on an action point of the force measured by the pressure sensor.
