Headphone sound-quality variance comes more from user and content variables than target-curve refinements

Evidence

The development of such models is also a tedious and demanding task, and objective models can never fully replace subjective evaluation. The advantages of objective models lie in efficiency, rapid evaluation, and repeatability of results. The development of such models may also yield a deeper understanding of the phenomena than subjective results. The disadvantage of objective models is that they never take into account all factors in full detail, and thus their domain of validity (meaning that they correlate well with subjective results) is limited. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2337 (#corroborates, via linked claim)
