I think you are just looking for trouble, why do want to change headphones if you are super happy with ones you have ? Buy another pair if you just want to spend money

For a moment I thought you had a child or something really exciting

You will probably get different kind of anwsers so why don't you take your conclusions since you already buy them ?

I only use EQ to fix something isn't right , if I enjoy the sound signature why messing with EQ ? I basically use AutoEQ with some IEMs I bought just because I want to try something different but didn't work for me

Did you already try foam tips? , personally I hate them but the seal is pretty good

The AutoEq is to solve a problem with some headphone if you don't really appreciate the sound of it , I only use it basically with my KZ IEMs , not because they are bad but because I didn't know what I were buying at the time

I have the Q30 and they are very enjoyable with AutoEq , they cost 60 euros but I wouldn't pay so much for a Anker headphone considering you can buy a HD560s refurbished for less than that or the momentum 3 for almost the same price , also sennheiser refurbished
