Sonarworks Tru-Fi has worked wonders for me on some of my other headsets.
Audio-Technica ATH-MSR7, Sennheiser HD 518, KZ-ZS6 - even my wife's Apple EarPods and the 'Samsung Earphones tuned by AKG' that came with my S9. Lots of other sets are there - Beyerdynamic, Focal (Clear, Elear, even the Utopia), even the Fostex TH-X00, BUT
Koss is poorly represented. Porta Pro Classic and Pro 4AA - really??
I can only be one voice requesting they add...
