Just get a toxic Black widow 22awg cable..best cable i had until now for my he500...excellent built quality,gorgeous looking, no microphobics, bass is real bass, mids are velvetly and that treble..
and its comparitive affordable
I myself could buy a more expensive silver cable..and i tried one..but it was to bright for my he500 in combination with the rest of my rig...imho.. For the he500 u wont regret buying a toxic black widow 22awg awg guys
thats why i just got myself a completely balanced cable in 8wire version of the BW 22awg....two cables from beginning to end..one for left and one for right..i think this is my endgame cable
