Here is my promised report:
My two microphones arrived today and they are very similar to the ones from mjrippe.
But there are some minor differences:
The basket/grill is made of metal but the rest of the upper half of the microphone is made of plastic. The metal basket is not connected to anywhere but this is not a problem because there is only a 9,7mm x 6,7mm OMNIDIRECTIONAL capsule inside - the cheapest you can get (marked "SG").
This capsule is embedded in a 16mm foam-ring to fit in a 16mm-capsule-holder, well known from Neewer/Tonor-microphones. But there they use at least an unidirectional 9,7mm capsule.
This capsule is directly connected to pin1 and pin3 of the XLR-connctor - pin2 is not used. No transformer inside and no other electronic components, so unusable on 48V. In my case they even ommitted the "lead" weight (if this is really made from lead. From the consistence I suspect these weights are made of steel-debris from the twin-towers or something similar).
So a classical case for a refund/buyer-protection (and probably two mic-bodies for free).
What can we conclude from this ?
Chinese folks are able to learn - here is the proof:
Many, many years ago, at the beginning there was a soundcard with a 3,5mm socket. Tip was audio signal, sleeve was ground and ring was 5V via a 2k2 resistor. So one could either use a dynamic mic with only tip and sleeve connected or an electret-mic with tip, ring and sleeve connected.
Then came the chinese folks and found the schoeps circuit and made clone-mics where they claimed that you could connect them to your pc.
They even put a second pcb inside which was not connected to anywhere - some where assembled + soldered, some were only assembled and some where empty.
After many reclamations they tried to adapt the schoeps circuit by changing the zener-diode from 9,1V to 3,1V in the hope that know the mics will run from 5V pc-supply too.
Since this was bogus and they had again tons of reclamations they sold their mics with a phantom-power supply.
But then a clever guy had the cognition that all these parts are not needed and reduced the circuit to one buffer-transistor, a cap and two resistors.
With time another guy probably thought "why waste all this components " lets connect the capsule directly to the mic input of the pc.
And then we were at the beginning, a sound card who had a 2k2 resistor to support electret mics. Yes it took some time - approx. 25 years - but in the end they have learned how to connect an electret capsule to a computer as it was originally intended....
