From your feedback, I gather you bought them from Audiohobby, correct? If so, yes they are fakes, frauds from China or Korea. He sold hundreds of these on the internet. If the jackets are a urine yellow with a greenish cast, and smell like cheap PVC, they are fake. The real ones are a dusty gold color. The Wattgates will both say 320 on both ends--that is wrong, and they are fake and dangerous plugs.
If you open one up, you'll find the screw terminals are cheap junk that hardly hold the wire. Also, the fake ones have bare wire ends, whereas the real ones have small silver clips covering the bare wire. The fakes are made from fake silver-coated garbage wire; not plated through the special process vdH uses with ultra-pure & highly-smooth silver.
If they are 5 foot lengths, they are fakes. They come in 1.5 meter, which is not 5 feet.
They may work fine, even sound good, but the risk is there for fire, shorting, etc.
