All that, plus with wires, I can run the cable under my shirt and up through the neck hole. When someone starts to talk to me, I can just pop them out of my ears and let them dangle across my chest without having to hold them in my hands. I also don't have to worry about dropping them on the floor.
This was common for kids in the 00s. Having just one bud in while talking to someone was common. There was also this type that instead of having two equal length wires, one to each bud, was asymmetrical and you would wrap the longer wire around you neck so you could easily "unbud". Sony invented this, I think. In fact there were some pretty crazy designs before Apple made the simple but conspicuous earbuds popular again.
