ZachLI own both. The King has more width and depth soundstage. Its vocal has more "water", "micro reflections" than the 5 that means the King sounds more smooth and nature. The 5's vocal seems a little dry.
DersOlmazHi, these upgrade cable are more expensive than the headphones. They just make about 5% better sound if you do AB test with the stock cables. The different mattrials used of the cable will change the tuning of the headphone. And of course they looked much better...haha.
ZachLI am very interested in this feedback as well. Just bought the Exclusive 5's and love them. Curious to see the sound difference and if it's worth buying them.
