It has all the writings on it like mines.Every 846 has a 3-digit number embossed on the bottom of them. Also all the 846 does have the Shure name and numbered components on at least of the earphones (the right one if I recall correctly). The only outwardly and immediately noticeable change might be the outer shell as I do believe they made slight changes to them.
It's just the bottom of it doesn't have the gold spot and the chips are smaller.
Other than that everything else is the same. I just don't understand why Shure would change the design. On the box it came in, the design is still the same as the original with big motherboard chips.
