No I don't have K99 just had to fix my SONY-SA5000 all I can say IMO they sound alot better than they did with the stock drivers and I have read a fare few write up's that said the K99-K100 sound better in open Headphones not sure if thats a fact or not..I don't have any Focal's.. I have Grado GS1000i, Sony mdr-z1r, mdr-z7m2, SA5000, IER-M9, Mrspeakers ether-C-flow,Aeon flow Closed, I wouldn't say that the K100 in SA5000 are as good or better just different and they sound good, Cheers
