On the SR-325, the 325is were never available in gold; the color variations also indicate model changes (SR-325i were done in gold as a 50th anniversary thing, 325is exist in both matte and chrome). However a lot of retailers seem to have not changed their stock images with Grado's latest revisions - it's only been what? 3 years?
I wish I knew that before I wasted my time and ordered them off Amazon through the seller 4ourears... I thought I was getting the gold ones (as displayed in the stock photo) but I was sent the silver ones, which I thought looked cheap as hell. I probably would have kept the chrome ones if I were sent those.. Just a tip to anyone reading this looking to get 325is.. MAKE SURE YOU CALL the seller before purchasing to make sure you get the color you want.
