发明名称 Headset structure with built-in audio source
摘要 A headset having a built-in audio source and cable management mechanism is disclosed herein. The headset is composed of two loop-style earpieces and a cable connecting the two earpieces. One earpiece has a built-in audio source such as a MP3 player, an AM/FM receiver, and the like. The cable is for delivering audio signal from the audio source built in one earpiece to the other. The other earpiece has a built-in cable winder so that the cable could be pulled and fixed to a desired length. When the headset is not in use, a slight pull and release of the cable would allow the cable winder to retract the cable back into the earpiece.
