First Test of Estimated Harman Target Response Curve on Various Headphones
As many of you know, Sean Olive and crew over at Harman International are developing a new target response curve for headphones. In this post I've modified InnerFidelity headphone measurements on a number of widely known headphones in order for you to have a first look at what the frequency response of headphones might look like with this new compensation curve.
The curve I used to compensate for the headphones is shown at the top of this page. The Harman curve (or a preliminary version of it) can be seen below.
I did modify the curve slightly, however. Above about 5kHz, when I used the Harman curve for compensation, I found the response in that area to be significantly elevated relative to what I hear on the various headphones. I therefore changed the curve a bit by elevating this region about 1dB to 5dB as the response moved from 5kHz to 20kHz.
I then made copies of a number of headphone measurement spreadsheets for a number of popular headphones with which enthusiasts will likely be familiar. I'd very much appreciate your feedback about the compensated frequency response plots on this page and how well they match with your listening experience.
Without further ado, I present a crude rendering of what compensated headphone frequency response plots might look like in future.
Please note that one of the reasons I did this is I'm in the midst of reviewing the Audeze LCD-X and found the sound of their headphones tipped up in the mid and upper treble more than I've experience in the past. I also had a hard time feeling they had enough bass after being exposed to the Focal Spirit Pro and NAD VISO HP50, though they're obviously well extended. Anyway, I got suckered into this rabbit hole and found the exercise illuminating and though you might feel likewise.
What do you think?
