So, i wanted to make a flat response handheld condenser since forever.
The capsule sourcing was an issue, they are rare and expensive in cardioid variant.
And then i bought Line Audio CM4. I was sceptical at first because of the price, until i tested and measured the thing. It is truly a ruler flat cardioid! At least in my testing conditions, and since Line Audio claims that as well, I consider it to be flat.
So i took it apart, in order to find out what it's about, and make my own version. In the end i gave up, it has rather complex circuitry with some advanced filtering (i hadn't seen in a mic before), and it has a phisically modded capsule which costs about 50$ stock.
So it simply can not be made as a DIY, at this price, and dimensions. It uses SMD.
So i took another road. I decided to put the whole thing, since it's tiny in a Neumann KMS105 chinese knockoff. I removed it's internals, which were not impressive, and whole CM4 fitted inside. It works remarkably well.
Maybe someone gets inspired by this. The great thing is, you just unscrew the XLR screw, and remove CM4 when you want to use it on it's own.
Here is the self explanatory XLR adapter:
