See, you also lose me at non-removable cables as a point of failure, for the same reason OP loses me at "toothbrush"

Oh, a great new idea then!

What if the same port could be on both headphones and phone?

For convenience, we could make it, like, round so it could go in which every way.

Then you could use whatever male-to-male cable you want if and when the one you have goes bad.
