Did you just order a single pair? Since it does take between 2 and 3 weeks to get them, that is why one should order about 6 pair at a time. You never know when you'll need more. Also, when it comes to Acrolink, the FP-640 was an older variant, which has been phased out - according to my understanding. The FP-650 is of the newer design and features gold-plated pins as your picture indicates. Also, they make a FP-650(R) model, too. That model has the Rhodium plated pins just like the Cardas Sennheiser plugs do. Depending on where you buy them, will determine which variant of the FP-650 that you'll get.
For the regular (gold plated) FP-650, I've found that these are readily available on LunaShops. Also, there are a few vendors on Ebay who sell this model, too. Again, shipped out of China.
To get the (Rhodium) variant, one would most likely have to go through Alibaba.
Now, this is where it all gets tricky. LunaShops will have their price stated and you can purchase the product right at that time via the order you place. You'll know the purchase price and if there's any shipping, etc. Going through Alibaba, you provide the information on what you're looking for, the quantity, etc. Within a few hours, you'll be contacted by someone who will provide the pins for you and the cost. The odd part is that the shipping will be around $20. On my first inquiry, I requested a quote for 5 pair of pins and had a total quote of $50.00. I then changed my requested number to 8 pair, and the quote went to $70. So, you can get the pins for $6 to $7 a pair, and the shipping will run about $20. To get the FP-650 - as suggested from Lunashops, the price will work out to essentially be the same - or, about $10.00 per pair of pins. If you want the Rhodium pins, you'll have to pay slightly more if you don't need a larger quantity. In that case, you might then just consider locating the Cardas pins. Normally, they are priced in the $15.00 range. I've seen them as low as $12.00 at Parts Conexion on a sale, though.
