## Abstract

A system includes first electronic device in communication with a second electronic device. The first electronic device has one or more motion detectors determining an orientation of the first electronic device in three-dimensional space and a first communication device communicating an indication of the orientation of the first electronic device to the second electronic device. The second electronic device has at least a first audio output and a second audio output delivering audio signals to an environment of the second electronic device. A second communication device receives the indication of the orientation of the first electronic device in the three-dimensional space. One or more processors cause at least one of the first audio output and/or the second audio output to alter the audio signals when the orientation of the first electronic device in the three-dimensional space changes.
