How did these things become the standard design?
They suck.

So now i'm looking for the earbud style, i.e. inside the
ear. They range from $8 to $40, and Shure offers a set,
over $100?!? For something so small, how can there
be such a range? Is there really such quality difference?

They are all sealed in blister packs, there's no chance
to compare. Even if there were, differences in
environment, time of day, etc. swamp perceptual
discernment.

How would you go about testing these things, in the lab?

Epoxy works well.

You would have to make an artificial ear canal and place the
microphonic transducer at the 'eardrum'end of it, and the earbud
transducer at the test point end.

With that keeping each test on the same set-up, the results should all
track, even if the numbers are off or 'uncalibrated'.to a specific
measure. Until you calibrate it (the input to the mic), of course.

That would be dealing with the position and angle of the mic transducer
at the 'eardrum' end of the channel.
