I stumbled upon a link to AutoEQ in another thread and searched to see if it had it's own dedicated thread (this will be the first).
Short version:
Jaakko Pasanen (don't know him) took the Harmon target curves for 2018 (Headphones) and 2019 (IEMs) and crinacle's measurements database and wrote some python to output EQ recommendations to apply for each device in crinacle's data. It's a crazy huge library. I've been testing for the last couple hours and I think Jaako is on to something.
Steps:
1. Install Equalizer APO and the Peace UI.
2. Find your headphones in the EQ recommendation list on Github.
3. Copy the contents from the "ParametricEQ.txt" file into Notepad.
4. Add a new top line with the pre-amp settings (found in the text of each headphone entry), here's the one from the BLON BL-03: "Preamp: -7.2 dB"
5. Save the file with a name (e.g. the headphone make/model).
6. Open Peace.
7. Click the import button (see image below), load the file you saved in step 5.
8. Click the save button. It defaults to the name of the file you imported. I added a link to the EQ settings page from Github for each device.
Note: you can also use the Peace UI to change EQ settings, but then it forces you to use increments of 0.5 db instead of 0.1 db that the EQ recommendations use (edit: unless you change the default in PEACE's settings). Make the changes in the file for more accurate results. Also, you should know that Peace will disappear for a few seconds between switching EQ profiles. It's a feature.
At first, I didn't care for it. It made the music quieter and I had to turn of EQ and rapidly turn down the volume to A/B test the EQ settings vs stock tune. And as you'd expect, loading an EQ for a different headphone/IEM makes your music sound like hot garbage. I tried listening to BLON BL-03s with the EQ settings for FiiO FH7s... and it was upsetting. After EQ, I can hear all the details in the BL-03 that I can in the FH7, but just not as clearly. It doesn't make the BLONs into an "A-Tier" IEM, but it makes it a pleasing muddy audio experience. I already thought the FH7 was pretty solid, but I think it sounds fantastic with the EQ profile. Since the software and settings are completely free, it's kinda crazy not to try out. I was considering pulling the trigger on a hardware EQ deck to add bass to the Koss ESP/95X on the way from Drop, but this should do the same thing, but cleaner.
What's crazier? Jaakko posted the python code he used to create the recommendations. So if you have a measurement system for headphones/IEMS like this, you create an EQ profile for your actual headphone, not the sample that crinacle got his hands on. Could be clutch if you're into headphone modding but also want to chase a target sound curve.
