People say this, I don't find it to be true. I still got the cable stuck on door handles all the time when it was tucked into my shirt, because finding the perfect cable length is impossible. Either way, the main problem remains; I want to be to move around a room with my headphones but without my phone/computer. That requires wireless.
Never happened, three feet is perfect for head to waist pocket. With cable inside shirt it is impossible for this to happen, perhaps you did it differently.
People are different heights, and it isn't only differences in leg length. Maybe for you three feet is the perfect length for head to waist, but that's not universal.
If you are shorter than 3 feet you can just wrap the cable around the device or shove it in the pocket with the device. If you are longer than 3 feet on the torso you are quite a human specimen anyway and are probably buying a lot of custom things for living your life.
Or... you could just get a wireless device and not deal with wrapping and shoving cables every time you want to listen to something. I put airpods in my ear and the music starts playing. It's just a much better experience than wired headphones were. No reaching through my shirt. No getting the cable caught anyway. No pulling my device around when I get up but forget to unplug.
