Most mono microphones will be fitted with a plug that has a tip and
barrel, but no ring (between the two). The effects you observe could
be no more than chance vagarities in the mechanical construction of
plug and socket.

If you want to know whether the input is stereo, plug in a cable which
has a stereo 3.5mm plug going to two phono plugs. (These computer↔monitor
sound cables were everywhere at one time.) Touch just the pin of each
phono plug in turn and see if you get mains hum separately on the
left and right channels of the computer.

If you're keen to use these microphones and you have the budget and
attitude of a school pupil, buy two mono 3.5mm sockets and a twin
phono socket unit. Solder the connections yourself using the phone
socket pair to anchor the 3.5mm ones and give it stability. Then
connect this device to the computer with the aforementioned cable
and plug in the mikes.

Cheers,
David.
