If you have EqualizerAPO you can save this as a .txt and import it into the app:

Preamp: -2.1 dB Filter 1: ON PK Fc 21 Hz Gain -1.4 dB Q 1.400 Filter 2: ON PK Fc 82 Hz Gain 1.5 dB Q 0.800 Filter 3: ON PK Fc 440 Hz Gain 1.5 dB Q 0.800 Filter 4: ON PK Fc 1900 Hz Gain -1.6 dB Q 2.000 Filter 5: ON PK Fc 4300 Hz Gain 1.7 dB Q 1.000 Filter 6: ON PK Fc 7200 Hz Gain 3.3 dB Q 0.600 Filter 7: ON PK Fc 8000 Hz Gain -6.0 dB Q 2.000 Filter 8: ON PK Fc 15000 Hz Gain -6.9 dB Q 0.500 Filter 9: OFF PK Fc 0 Hz Gain 0.0 dB Q 0.000 Filter 10: OFF PK Fc 0 Hz Gain 0.0 dB Q 0.000

To get that I did what someone else already described, by visiting Squig.link, finding both the Dioko and Truthear Zero Red, going to the Equalizer tab, setting the EQ model to the Dioko, hitting autoEQ and exporting.

Late to this, but I just found a real solid Harman-like eq for these using squiglink. I have been thoroughly enjoying the sound.
