I'll quote the first paragraph of the conclusion:
Based on the evaluation of the mean, variance, PCA, and mean square
error with respect to a target function, no correlation could be
observed between the measured magnitude response and retail price of
headphones. However, the variance in low-frequency response seems to
decrease with increasing price, indicating an improved bass response
measurement consistency across headphones in the higher price range. It is
however unclear whether this improved consistency with a higher retail
price is the result of better headphones or better repeatability of
measurements with more expensive models. Nevertheless, assuming that the
perceived audio quality is largely determined by the spectral magnitude
response of headphones, there are plenty of relatively cheap models that
match the assumed target function, as well as very expensive ones that
deviate significantly from an assumed ideal response.
I imagine that this paper is largely unsurprising to r.a.h-e regulars.
