Warm Audio WA-87 R2

Firstly, I would say this mic is the best vocal mic that I have ever owned.
I owned Shure beta58a, Share SM7DB, ATH AT4050. For sure this mic give me the most satisfaction, it's warm, full and presence.
The problem is that when I received my mic, I observed there is some small clicky sound inside the mic body.
It sounds like some small part has been apart from the circuit board.
I am not sure if this is a defect or a normal phenomenon, but for me, I get a bit nervous of the build quality.
Now working with the engineers for checking, hope it helps.
After all, I will still recommend this mic considering the price and sound quality.
