1. A method, comprising:
capturing, using an imaging system, one or more images of an audio device and an anatomical feature of a user of the audio device;
identifying a datum of the audio device based on the one or more images;
determining a relative position between the anatomical feature of the user of the audio device and a speaker of the audio device based on a position of the speaker with respect to the datum;
producing an equalized audio signal by applying audio equalization upon an audio signal based on the relative position; and
driving the speaker using the equalized audio signal.
