MunkyNuts, You are welcome.
A friend of mine bought a pair too. He compared them with his K702 on D50 and decided they are genuine. I put an offsite link of a photo of his hps and hopefully the administrator will let it to be shown later.
After listening to them for 10 hours, I am also pretty sure mine are genuine.
Beside, in that online shop, you could find other "cheap version" hps, some of which were even on shelf before its official release! There is no way to fake hps in advance. So I think only someone who has a connection with the OEM factory could do that. The shop owner used to sell these on ebay. But the deal was over.
I can not rule out the possibility that some of these hps might be defected. And you'd better be careful of focal hps, they are pretty fragile and the first batch of spirit one was defected as I know.
Anyway, it's still very risky to buy cheap stuff from Taobao. Our Chinese people are too good at counterfeiting :(
