I got this email from the seller not long after contacting him. He was very apologetic, and is letting me keep the GR-06s, which I may just pawn off to a friend to recoop some money. I can see it was an honest mistake, and I'm hoping it doesn't take too long to get the correct ones.
"Thank you for telling us first. We are so sorry about this matter.We are checking the waybill and shipped item. If we shipped a wrong headphone actually, we will send the correct item you bought immediately.At the same time,the GR06 will be given to you as a compensation for your waiting. So, could you please kindly take several photos about the earphone you received? If it is ok, please put the headphone in the packing box first,then photograph the frontage and left side of the packing box so that we can check the item and the numbers in the left side of box. Finally, please send these photos to our emailbox(firstname.lastname@example.org). Thank you very much for your kindness and patience."
