A vehicle head restraint includes a speaker positioned directly behind a head of a vehicle passenger occupying a seat when the vehicle passenger head is substantially centered in front of the head restraint, a head restraint support defining an internal open cavity, and an acoustically transparent material supported by the head restraint support across a forward face of the internal open cavity. The acoustically transparent material restrains the rearward motion of the head of the vehicle passenger and the speaker is directed toward a center of the head restraint.
