HEFIO - Headphone Fidelity Individually Optimized

Just as loudspeakers are calibrated for the room they are placed in, headphones should be optimized for each ear they couple in order to adjust the sound reproduction for the unique ear canal acoustics of each individual. By individually optimizing the headphone sound reproduction, HEFIO delivers the sound with outstanding clarity, definition, and neutrality to the eardrum of each individual listener; providing an aural experience on headphones that can only be achieved in professional listening environments with loudspeakers.
