It's not a Shure; I worked there 20 years.
It is shaped like the E1, but that had a beige case. And there was never a version with a clear case. Maybe this was Westone's version? (Originally, Westone was the source of, and manufacturer of, Shure's original E1. In fact, you can trace Shure, Westone and Ultimate all back to the same common roots. And by extension, JH, too, come to think of it.)
If it's from that E1 family (BTW, I still use my E1s on occasion...), that would make it more than 10 years old - likely closer to 15.
