Abstract
An ear module, which can be selectively worn on either left or right ear, comprises an interior lobe, adapted to fit within the concha, comprising a speaker and a compressive member/cover assembly. The compressive member/cover assembly is positionable, typically rotatable, relative to the remainder of the inner lobe between left and right ear orientations to permit the ear module to be worn on either the left or the right ear. A method for improving the quality of sound emanating from an ear module includes selecting the sound bore within the ear module to help improve the frequency response of the ear module so that the ear module has a resonant peak near 2.7 kHz and a maximum 20 dB decrease in high frequency response as measured at 5 kHz from the average frequency response as measured at 500 Hz, 800 Hz, and 1600 Hz.
