Want to skip a track? Fish the phone out of your pocket, turn the screen back on, find the skip button, tap it, wait a second until the garbage app acknowledges that you’ve pressed it, turn off screen, put it back.

I had a HTC Touch Pro smartphone 15 years ago, and it had an optional headphone cable with buttons on it. You could use the buttons for pause/play, next track, and previous track, without having to get the phone out of your pocket.

I never really saw something like that again for wired headphones. I did sometimes see headphones with buttons on the headphones themselves, but often they just have play/pause.
