I'm looking at a sealed UK bought unit from Amazon, only purchased last week as a b-day present for my bro. Looking only at the earpieces through the window (I'm not opening the box sorry!), the earpiece shape and cable attachment from the earpieces is the same shape and design as the ones you have pictured above.
Except the "Shure" logo is
different slightly as you can see. As you say you don't have a fit kit or wax guards and if it was sold as new, then its either 2nd hand or pretty good fakes
