There, I fixed it.

My current pair of headphones that I found abandoned in a supply closet at my summer job from two years ago finally wore down, in the form of the left side not playing. Well, not playing unless tilted and held at the exact precise angle. I wasn't too upset, just disappointed, and two years for these things after all the banging about on commutes and vacations, from airplanes to archives, was pretty good.

Then I realized I could reinforce the wobbly tilt at the jack site itself with tape and get at least two more weeks' usage out of them, which is enough time to find a suitable replacement. I don't know if I'll get the exact same kind or something new - just that I didn't have to do it today, which I'm pleased about.
