I've always thought that matching certain headphones with certain headphone brands is such a silly thing... like matching the Grados with rock music. which rock music are we talking about? which guiter player? which guitar? which fuzz pedal? which producer? etc... the number of soundings are simply countless.
i think you meant "certain brands with certain types of music". and i totally agree. as soon as someone starts saying "brand x is good for classical and terrible for rock" or whatever, i start to lose respect. especially when people start to get really ridiculous and try to specify the "type" of rock music. "These are good for prog but not metal". Or "those are good for metal from 1982-1999, but terrible for metal after 1999." I mean, c'mon. This is getting into Monty Python absurdity territory.
