Designed in California assembled in China is missing in my Earpods

I bought earpods in the online store... and I think its authentic, because it came from iPhone 5 package , the only problem is there is no "Designed in california, assembled in china" sign in the wire, my question is, is that possible that even without the sign it will be considered as authentic??? is the first batch of earpod came from first batch of iPhone 5 doesn't have that sign??
