Yes, Tyll discussing Harman experiments and the different types of target curves, but his measurements having nothing to do with Harman. Like I explaining before, the compensation curve is having no ralation with the Harman curve.
A lot of the success of Beats is in relation with Beats being a statement of fashion (the design being very important) and very expensive product at the time (today prices can being crazy in many brands), with endorsements and celebrities wearing this headphones. The bass emphasis of early Beats only making this headphone producing big 'wow' effect, specially with music with a lot of bass emphasis (rap/hip-hop and genres with this influence) is so popular. V-shaped headphones, very common today is the equivalent of turning on the old 'loudness' setting (increasing bass and treble) that making the sound very exciting and making a big false artificial soundstage.
Because people using headphones and earphones outside (without anc) in the street and in public transport more and more, more bass and treble is 'helping' this headphones sounding 'better'. This is too one reason the loudness wars (bad dynamic range) becoming worse and worse. This increase of bad DR is strongly in connection with portable earbuds (not in-ears or headphones) where the outside noise is coming inside the ears very easily because earbuds having shallow insertion, sitting outside the ear canal.
The graphs I seeing of h6 telling me that I will not liking this headphone. I don't think is very balanced at all.
