What does MMCX mean?

MMCX is the abbreviation of Micro Miniature Coaxial connector (Actually four dumb capital letter that looks like Roman numeral but nobody cares what it really is). MMCX connector is a very small connector, even smaller than your smallest fingernail.

This MMCX connector thing is used for earphone? Why have I not seen it?

MMCX connector is traditionally used in antennas. It was not until recently did it apply to the earphone field for its reliability and small size. MMCX connector's application in earphone industry is limited to high-end earphone so we do not see it very often on ordinary earphones. (Yeah, for people like me that have not used any high-end earphone over $100, No, we do not get the chance to see it)

Earphone usually uses a 3.5MM connector to plug to an audio device, so is this where MMCX come in, to replace 3.5MM?

No. MMCX do not replace 3.5MM. It coexists with 3.5MM in the same earphone.

What is the position that MMCX is applied to earphone?

MMCX is used to connect between the loudspeaker and earphone cable. In ordinary earphone, the loudspeakers are directly connected to the cable.

Why do high-end earphones need MMCX connector?

The reason why high-end headphones are adopting MMCX connectors is simple. No matter how rigid the design is, the biggest cause of headphone damage is the cable. Trashing away an expensive headphone with the main unit still function well is not just annoying, but costly. Therefore, detachable cable has become a trend and if not, the signature of any high-end headphone models.
