Thanks to friends at tapersection I now have several pairs of these.
My second pair was just modified by removing mic from case, and wiring a cable to it with shrinkwrap. Similar to what Moke did, but instead of a brass tube, I just covered everything with heatshrink LOL.
During this process I removed the mesh and the waterproof covers on the mic. There is a thin diaphragm, some kind of spacer, and a standard (4.5mm) MKE2 capsule underneath.
I believe there is still an extra "umbrella diaphragm" inside the capsule, just like the standard MKE2.
These sound very nice. Will be using them for (dry conditions) field recording.
