> The target function suggested by Olive and Welti (2015) is fairly similar to the average headphone response found in this study, with the exception of a deviation of up to about 5 dB for frequencies between 50 Hz and 2 kHz. I find little fault with the arguments laid out supporting the paper's thesis. For those commenters making the jump to "sound quality" (which is not the topic of this paper), the quoted observation above conclusively proves that these headphones have differing tonal qualities. Even a casual listener will be able to hear a difference of 5dB in the critical freq range of human speech.
