I tried auto-eq and ngl I think it sucks, but that obviously just means I didn't like whatever target they were going for. I recommend trying the oratory1990 eq, that way you can even play with the bass if you don't find it enough using equaliser apo and peace.

I was looking into some other JM edition hp but couldn't see any warranty information, can't imagine spending 500 let alone 200 on a headphone without a warranty, but these guys have partnered with him so I think you get one with these which is good.
