摘要： A headphone and a headphone state detection method are provided. A signal processor receives a sensed signal generated by a sensing unit, and determines a contact state based on the sensed signal. In response to that the contact state is in no contact, the signal processor sequentially sends a plurality of pieces of code information to a first sound playing unit such that the first sound playing unit plays a plurality of first audio signals corresponding to the code information according to a playing sequence, and determines a wearing state of a headphone according to a plurality of first time points when a first audio receiving unit receives the first audio signals subjected to first reflection. In response to that the contact state is in contact, the signal processor stops sending the code information.
