AirPods and the Phantom Limb phenomenon
Not trying to belittle the plight of amputees in any way. However, I noticed this phenomenon while using my AirPods today. I was constantly and automatically reaching for the nonexistent "cord" to move it out of the way, reach over or underneath it, or otherwise try to keep it from getting snagged or tangled. This was especially noticeable whenever I took my coat off or put it on.
Of course I'll get used to it not being there, but that just means any wired headphones I use in the future will be toast mere minutes after I put them on.
