That's an understatement. If your fine motor skills aren't impaired, you should spend maybe a few minutes each year rolling and unrolling your wired headphones. I'd argue it takes nearly as long to put your AirPods in their case and set them down on a charging station.
Except the original post said to "count the time you spend untangling the cord" (which, for most good, flat-wire headphones is almost zero). Habit or not, charging takes more time than properly rolling the cord on wired buds.
