Someone else's earwax on brand new Apple earbuds?

I was just wondering how often the manufacturers that produce the Apple earbuds test them? Do you think they have to test out every pair that's produced or just some of them? Because I bought an iPhone 6S Plus from Walmart. And earlier when I took the earbuds out of the (sealed) package, I noticed that there was a tiny amount of earwax on the inside of both buds.

Write to the CEO of Apple. At the price of an iPhone, that should not have happened.

Nnaybe you should bring it back and exchange it for one that don't have it

Those were Not new!

Get a replacement set.
