A wireless headphone device has a first elongate portion having first and second opposite ends with an attachment interface at the first end, the first portion comprising an on-board power supply and a transceiver with functional circuitry, and a second elongate portion coupled pivotally to the first portion at the second end, and having an ear bud and a microphone at an end away from the pivotal coupling. The functional circuitry enables receiving and playing of audio from an MP3 player through the ear bud, and use as speaker and microphone for a wirelessly coupled telephone.
