Cables and switches always break first. It's the same in power tools - any component that you have a 200-pound gorrilla mucking around with every day will eventually break. You can mitigate this, but you can't eliminate it. It doesn't mean they're bad design.
That said, I think a good, working bluetooth solution would be something I'd prefer. I like analog jacks, but honestly, cables are a bad solution for wearable devices.
