it's been discussed here more than a few times!
Simply put: current connectors suck. Full stop.
MMCX is NOT for audio/consumer applications. It's a micro-RF connector intended for crimped-on cables, that are positioned one time (connecting a WIFI or Bluetooth antenna to a main PCB, for example) and then glued down so they don't move. It's a connector designed for a dozen or so insertions, and basically no rotations. Kind of the exact OPPOSITE of what you want in an audio connector. Which is why people always complain about them failing.
Furthermore, the MMCX standard is so loose that I can make an MMCX jack that is 100% standards-compliant, and you can make an MMCX plug that is 100% compliant, and our parts won't mate (not that uncommon; many don't realize that you could make a CD that 100% within tolerance at the high end, and the CD could not be read by a CD player than was 100% within tolerance on the low end - they didn't completely overlap).
The two pin solution from a several suppliers is nearly as bad. They are typically poorly polarized and you can insert them backwards. They're not that reliable because of the soft plastic wear. They don't rotate. And there are a dozen different styles that are all "close enough" you COULD force them together, but they are actually all different mechanically, meaning you can damage them just mating them.
So rather than go with a poor solution, we went tried-and-true: overmolded ABS and urethane on a heavily reinforced cable. The ABS is designed to mechanically lock in to the main body with 6 finger hooks, and is glued tight with cyanoacrylate. It won't come loose without a LOT of work.
The cable is pretty bipolar too! We get lots of concern about it being so thin and "insubstantial", but at the same time people love how flexible and light it is. Well - those two are kind of related...
Either case, it comes with a 5 year warranty. If you absolutely need a removable cable, we'd recommend looking at one of the other brands around here; however, very very few people have cable issues at all, and if they do - we make it right, really fast.
