hi i have been looking at buy the hifiman he 500, however im not sure where to buy them because i have seen different sites show the hifiman he 500 coming 1 spare velour earpad. one with 1 pair of velour and 1 pair of pleather earpads. and also the cable changes from a white twist one to a black thick monster cable. i also remember reading that the white twisted cable was bad. will this affect the music ? i was just wondering does it matter which cable i get?
