Micro-miniature coaxial (MMCX) connectors are

coaxial In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable is a three-dimensional linear structure. It has a wire condu ...

RF connectors similar to MCX but smaller. They conform to the European CECC 22000 specification. MMCX connectors are rated to 500 mating cycles. The connectors have a lock-snap mechanism allowing 360-degree rotation and usually have a 50 Ω impedance. They offer broadband capability from DC to 6

GHz The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one he ...

to connect the cable to the individual earpieces. This allows for the cables to be replaced or swapped. They were developed in the 1990s. MMCX is also used in some video transmitters for First-Person View (FPV) radio control piloting. This makes swapping antennas and repairing easier than the U.FL connectors.
