If you are looking for the supposedly next best thing then there are the new pentaconn ear connector type.
They were designed as earphone connectors.
This is an interview with acoustune that started implementing them

There seem to be differences in batches thus far with slight inconsistency in term of grip/force for connecting and disconnecting but still should be much better than mmcx connection
This is the model name of that connector if I am not mistaken

They come in red, blue and black iirc. They also require a special connection on the cable end
