Something new with in-ear wireless headphones is making them all day sensationless with organic-all natural endorphins. Diffiusion (drug delivery) of the endorphins, also known as opiate peptides, occurs so that just that mm of tissue they press up against is anesthetized. Body moisture or undetectable
solvent (charged perfluorocarbon) at the plastic of the headphones migrates an opiate peptide into the skin.
Opiate peptides could use a name upgrade to like
digested wheat mu activator. When people eat wheat, one of the products in their GI tract are opiate peptides. It is just they are far from the brain.
Although spurious as a therapy at doses you would get from headphones, unless you have special actual working drug delivery wear-all-day headphones: some opiate peptides increase surviving tissue after a heart attack [link], if they make the headphone comfortizing opiate out of those then it's all upside.
This being the halfbakery, there can be actual humor content: Sublingual headphone high. Yes, some people if they hear there are opiate peptides on the surface of headphones might position headphones sublingually. No, I don't think sucking on headphones with picograms (even femtograms!) of opiate peptides would do anything.
Of course, there is an exception: If a person got authentic drug delivery headphones that transmitted a full body dose of something therapeutic, then actually, sucking on them might release a whole bunch more.
All of this works for earplugs and electric earplugs as well of course.
