1. A listening system comprising:
one or more remote signal sources that generate one or more electronic signals, which correspond to sound in an ambient environment;
a first ear microphone to detect a first combination of audio signals comprising ambient sound and one or more propagated audio signals, corresponding to the one or more electronic signals, received at a first ear of a listener;
a first ear playback device; and
a processing device coupled to the one or more remote signal sources, to the first ear microphone, and to the first ear playback device, the processing device to apply a first set of audio filters comprising an audio filter to process a respective electronic signal of the one or more electronic signals with a first error signal, which is based on an output of the first ear microphone, to generate a first output signal to the first ear playback device, wherein acoustic cue components of the first output signal match corresponding acoustic cue components of the first combination of audio signals.
