1. A tuned-frequency-spectrum earpiece for selectively tuning audio frequencies that enter an inner ear of a user wearing the earpiece, the earpiece comprising:
a base having an emitter end and a receiver end, and a stem portion located between the emitter end and the receiver end, wherein the base includes a channel that passes through an entirety of the base;
a sound-attenuation plug, wherein the sound-attenuation plug surrounds at least a portion of the stem portion of the base; and
a first frequency-spectrum-shaping sound-collection horn operatively coupled to the receiver end of the base and configured to selectively increase sound intensities of desired frequencies relative to sound intensities of other frequencies of the audio that enters the earpiece.
