no one answered your second questikn so here i am

a lot of audiophiles would not recommend the 599 because of its “muddiness”, where the bass obscures or distorts the rest of the audio’s detail. the clarity, soundstage, highs and mids are not very good compared to other headphones in the price range

but based on what you said it seems like the 599 would be a good fit for you. you seem like you love bass over everything else, and the 599s would absolutely satisfy you in that regard. their detail and clarity is still really great, good enough that they’d blow someone away who hasn’t heard anything better than skullcandy. i think they’d be more than worth your money

it’s always cool to see someone just getting into high quality headphones. whichever headphones you go with i hope you enjoy them !
