1. An electronic device comprising:
a plurality of speakers wearable on a user's head;
a gyro sensor configured to sense a rotation of the electronic device;
a memory configured to store a plurality of head related transfer functions corresponding to a plurality of orientations relative to the plurality of speakers; and
a processor, wherein the processor is configured to provide a stereo signal to the plurality of speakers from an audio signal by:
applying a first head related transfer function corresponding to a first orientation relative to the plurality of speakers to the audio signal to form a sound image in the first orientation relative to the plurality of speakers before sensing the rotation of the electronic device;
in response to sensing the rotation of the electronic device from a first direction to a second direction, applying a second head related transfer function corresponding to a second orientation relative to the plurality of speakers to form the sound image in the second orientation relative to the plurality of speakers, the second orientation relative to the plurality of speakers corresponding to the first direction; and
when a specific time elapses after sensing the rotation of the electronic device, applying the first head related transfer function to the audio signal to form the sound image in the first orientation relative to the plurality of speakers.
