Regardless of Sharur, Harman performed virtualizations (EQ) so that one headphone could sound like another, which is part of the methodologies used to develop the Harman Target. Among the studies conducted, individuals did not report significant differences between the original headphone and the equalized one, although there may be differences when wearing them in your ears. It is worth noting that the main differences will be found in the range of 1 kHz to 20 kHz, as these are the ranges with the greatest variations among HRTFs. u/West-Cheek-156
