The housing contains a receiver for receiving audio over a wireless connection, a microphone, a transmitter for transmitting audio from the microphone to the audio source device, and a processor capable of establishing the wireless connection. The apparatus further comprises a battery, a clip attached to the housing, for attaching the apparatus to a garment or an article of luggage, and a speaker adapted for placement on or in a human ear, coupled to the housing via a wire inside the housing and the speaker, such that the speaker, the clip and the housing appear as a single unit.
