Abstract
A headphone device includes a first audio output module, a second audio output module, and a head module connected between the first and second audio output modules that are located at both ends of the head module respectively. The head module stays bent when in use and stays straight when in compact storage. Thus the form factor of the headphone device in compact storage is relatively smaller.
