Could you add….
Sennheiser HD 660S2 & Yamaha MT-5
You have the Sennheiser HD 660S but not the HD 660S2 which is different enough to warrant its own EQ (it is highly respected). There was a request for more headphone EQs for Nx which was raised in 2019, so this also a check as to whether you might have an ongoing list, whereby you might add a few of the latest studio pro headphones every 6 months or year, or so? - to keep your plugins alive with the latest headphones we are using.
Seems like if you develop a tech like Nx this should be in its life-span design model of how the plugin exists? Maybe have a separate section just for this, headphone suggestions for Nx (and Nx related plugins). Or as a quick measure, go over to dSONIQ Realphones headphone list, basically you should be matching this, no reason not to.
