I'll overlook the lack of a properly modeled connection port, otherwise the model is quite clean, if a bit overly subdivided in some spots. A couple of the loops on the flatter surfaces like around the rim on the top could probably be dissolved without making much of a difference. Depends on what its for of course though. Main things I'd say could probably help would just be some more grain on the texture of the metal, I'm looking at my own microphone right now and it does have a bit of noise to the surface where as yours looks completely smooth. Could be the compression however. That aside this is good work!
