I started looking into headphones about a year ago and got pretty soon excited about possibilities of using equalizer to improve headphones. Then I got very disappointed of the lack of existing headphone eq settings. Disappointment turned into resolution and this was my reaction. Now I'm exited to present to you equalization settings for over 700 headphones: https://github.com/jaakkopasanen/AutoEq. This includes all on-ear headphone measurements from Innerfidelity and Headphone.com with 4 different target curves. Combined with EqualizerAPO this is essentially a free alternative to Sonarworks True-Fi with almost 5 times as many headphone models. Full details on how to use the eq settings and what else you can do with this can be found in the Github page. This is not supposed to be the be-all and end-all of headphone equalization. Especially the target curve is a tricky thing to nail down because Innerfidelity and Headphone.com measurements are not directly comparable with the measurement system used by Sean Olive and others for their Harman target response research. I would love to hear feedback from you fellow headphone enthusiasts. Do you think this makes your headphones sound better and what kind of problems do you have with these eq settings? I hope this makes equalization a bit more approachable for people who feel intimidated by it. Also keep in mind that you are allowed to tune the eq for example with HeSuVi to make it more to your liking.
