Google Translate says it's Estonian, meaning "Produced 3-2020"... Why Estonia ?
I think "WW2" is a region code the product is destined for. Based upon the languages printed on the back side of the cardboard box I think it could be Central and Eastern Europe.

I'm in Australia and the box says the same thing, but i'm looking at a few units from Japan on a website and the backside of the box looks very different. Guess we can't really know.

just because wanted to try the other guys in IEMs world, and now I can realize how good Z1R is, both the build and the sound :D

Final update on my aftermarket L eartip test and after using velvets for 72 hours I went back to Coreir Brass. Velvets are really strong in Bass and Sub-bass department but they also cut the sparkling Highs by a fraction which in my case and music preferences is not acceptable.

If you can, get a new unit, Z1R is worth buying brand new :)
