Sounds like jostling cables didn't fix or create noise so I doubt its a connector, but clean your connectors anyway, that's cheap and easy and may need to be done anyway. If it occurs again, swap the mics only, not the cables or anything else in the signal chain and see if the noise switches sides along with the microphone.
Moisture or dirt/smoke-film on the diaphragm of a condenser mic can cause a similar static like sound. If it's humidity or moisture, it often goes away after the mics warm up and drive the moisture off. Store them with some desiccant for a while to be sure they are completely dry. I had a Microtech Gefell mic exhibit a very similar type of static noise, which was aggravated by humidity, and needed to send it back to the factory for reconditioning. Came back as good as new though.
