Received my Noble Khan v2 upgraded from v1 which broke. Only several days old now. They are greatly upgraded in 2nd revision with bigger beautiful silver-shimmering set of faceplates, bigger shells printed in a different, sturdier technology, now with classic recessed 2pin connectors allowing as many cable swaps as you like (first Khan was not really recessed and could chip when swapping too much), I've also measured them and they're like +/- 0.5 dB channel matched (perfect). Overall, practically new IEMs. PM me for photos if interested.
