If you're visiting a foreign place, and use headphones to drown out important context clues that help guide you, that's your problem, not mine.

Not that big of a problem. The PA system is pretty simple, and it's easy to understand which is the next station's name, and what is just the "the next station is...." part of the announcement.
And you usually find metro maps in each cart, so it's easy to match the name you hear on the PA with what you see on the map. Technically you can manage without even the PA by looking at the map and counting out the stops, but you need to be very careful to make sure you're going in the right direction.
