I finally got to a computer and the first part of that sounds like it might be breathing (since it pauses), but the end part is too long and consistent to be breath, but it definitely sounds like air flow across the mic (or possibly a bad connection).
 
Do you get the same issue with the other mic in that package (i.e. just swapping one mic for the other)? This would help you better pinpoint the cause between the diaphragm picking up something (it goes away), or an issue with the signal path (it is still there).

Condenser mics pick up everything. It's probably just low-level room noise. A gate/expander plugin will take care of this if it's undesirable.

Sorry to dig up an old thread but I’m getting very similar sounds from my Peavey 6505 tube guitar amp...it’s plugged into a power conditioner and same thing with two different guitars.

Did you ever diagnose and/fix the problem?

Funny the OP to this thread never replied to anyone..

The usual answer.....bad cable or ground issue. It doesn't have to be the Mike or audio input itself, it may be a diff cable connected in the same overall system.
In one example I had a bad HDMI cable conn to one component that gave the same issue or hum, and when I disconnected that cable my entire audio set up lost its extra hum...
