Abstract: A method and personal stereo speaker system is provided for providing audio to a user. Speakers provide audio to the ears of a user. The speakers are preferably mounted on the shoulders of the user. The audio emanating from the speakers has a beam angle and an audio level. When the system detects that the head of the user has moved, either side-to-side, up and down, or rotationally, or that the user has commended moving, a controller changes at least one of the beam angle and the audio level in response to the movement. This improves the quality of the sound heard by the user and also keeps the privacy of the audio optimized.
