1. An auditory feedback system comprising:
an acceleration sensor configured to measure a body inclination of a user walking or exercising with a wireless earphone worn; and
a controller configured to determine whether the body inclination is greater than or equal to a predetermined angle with respect to a body center line,
wherein the controller controls the wireless earphone to provide a first type of music as first auditory feedback when the body inclination is determined to be in a neutral state of being less than the predetermined angle, and to provide a second type of music as second auditory feedback when the body inclination is in an inclined state of being greater than or equal to the predetermined angle.
