Batteryless noise canceling headphones include a first earpiece having a first speaker for providing a first audio output to a first ear of a user in response to a first audio output signal, and having a first microphone element for converting a first ambient audio input at the first ear into a first ambient audio input signal in response to a bias voltage. A connector receives the bias voltage from an audio device, receives the first audio output signal from the audio device, and provides the first ambient audio signal to the audio device.
