No they are correct. When my LCD monitor is on I can hear a definite
hum or buzz. When I turn it off it goes away, so I turn it off while
recording.

That proves the sum total of nothing other than poor product design. I know, I'm a
pro-audio designer and pretty expert in RF interference matters actually.

Because the microphones use magnetism to function they are
prone to these problems.

Rubbish. The fact the mics have a magnet inside is totally and completely irrelevant to
RF pickup. Where the hell do you get this crap from ? What is especially relevant by the
way is inductance and 'loop area'.

They sound good when they work,

As some badly designed equipment (especially esoteric hi-fi) often does.

I know that the RFI and magnetism problems are different. What I
meant to say is that the problems with dimmers, fluorescent lights,
motors, converters in close proximity and such are due to magnetism.
This is the reason why turning on my LCD monitor introduces hum. The
RFI problems are not related to magnetism. I know this. You just
misunderstood what I said is all, though I wasn't entirely clear I
admit. The mics do have problems with these things though they are
not due to RFI but a separate issue.
