They have a variety of connectors, but 3.5mm TRS and mini-XLR (used by AKG microphones/wireless with 4V through 4.7kOhm bias if I remember correctly, TA3M in the adapter) are common. If you are looking for a brand product, Røde has the VXLR+ adapter for their video mics (note that the + sign is important or it will not provide plugin power), also 3.5mm TRS.

Leave the ring (bias) pin open, do not connect it to anything. Most professional mics will be fitted with the standard XLR connector. To make a simple adaptor, wire the mic audio (XLR pin 2) to the sound card input connector's tip; wire the mic audio return (XLR pin 3) …

Most Android devices use 4 contact 3.5 mm plug for headphone/hand-free-set. The hands-free sets have microphones in them, so there must be a way to get signal into your device though this connector. I started looking around. I found that almost all smartphones expect the mike and common leads on connectors 3 and 4.

A lot of audio chips are 5.1 or 7.1 capable but on cheaper motherboards you may have only 3 analogue connector (by default, stereo out, line in, mic) So for 5.1, line in and mic jacks are reconfigured for center+subwoofer and rear/side left+right. For 7.1, headphone jack on front panel becomes those extra 2 channels above 5.1

Shure Tech Tip: Phantom Power vs Bias Voltage
https://www.shure.com/en-US/performance-production/louder/shure-tech-tip-phantom-power-vs-bias-voltage
Bias supplies power to a Junction Field Effect Transistor (JFET) connected to the output of an electret condenser mic element. The JFET acts as an impedance converter which is a necessity in any microphone design that uses a condenser element. A condenser element has a high output impedance (>1,000,000 ohms).
