ATR2500 Mic has electric current coming from it

[QuantumPrimus]

I have had this ATR2500 microphone for about 2 years now, and all of a sudden, while sitting at my desk, I went to look at something closer to my screen, and I got a little close to my mic. I have done this a few times, so I didn't expect this. When I got close to it, I got a shot to my face that felt a little strong. So I decided that it was a good idea to put my hand around it, where then I could feel a light charge going through my hand. The mic audio still sounds like it did when I listen to it.
What could be causing this to happen to only the mic?

In condenser microphone, you have two metal foils of some sort forming a capacitor with a 40-200V DC bias voltage in-between depending on the specific design, so that would be where you could get the shock from.

I don't know about the internal design of this microphone but in principle, the metal screen protecting the foils should be grounded and that would prevent you from getting such shocks. The fact that you do get shocks and that the unit still works tell me that the shield might not be correctly grounded and that one of the foils is likely making contact with the shield.

Smells like a manufacturing defect to me.
