Oh yea, I found out why those JVCs are so cheap.
Apparently it was because of a production fault, it isn't the seller.
I asked him about it and he stated that they would cover the discount offered for the lack of the cord thing.
"Thanks for your query.In fact, I have the same feeling with you at the very beginning.I also buy this huge stock when I was so strange about the goods.The wire cord is not included in the original package, this is the fault of JVC company.At the very beginning, when I discover that the wire code is missing in the package I immediately called JVC (agent). They claimed that they are the production fault from the production process. They are willing to provide me the discount for all FX3X products.After I tested that the headset is Original and 100% good condition I accept this huge stock and sell in the eBay. I also offer this discount to all eBay buyer. They accept this package and headphone without code since we offer them this lowest price and they don?t care of the wire cord when they replied that it is ok since the package has ?XX? case to keep the headset with the gift of wire cord.If you don?t mind the wire cord and enjoy only the headset, you may accept this offer. We pack the product well to you before shipping.Thank you.With Best Regards,Peter,17-Oct-2012"
So don't worry about it :)
