For your headphones, Equalizer APO should get you all the way.
I think you will have more flexibility by installing Equalizer APO and Peace and using it to equalize the sound instead of the Qudelix EQ.
EQ APO and Peace GUI is still the golden standard for PC :)
I've installed `Equalizer APO`
The 560S is a great headphone for the price point. Tell him to download equalizer APO and try to fix some of the tone issues.

I have not done a direct comparison, because in my setup, I have found very little audible difference between Audyssey, and A1 Evo Acoustica when using flat target curves.
got Acoustica dialed in with the last version
A1 Evo Acoustica is a fantastic tool and if you can follow the instructions, is simple enough to use without technically understanding what it does.
Try A1 Evo Acoustica first. It’s free and made an improvement to me over stock Audyssey.
I used to eq everything myself but switched over to A1 Evo Acoustica recently and love it. It really makes it slap.
