funny thing, I've noticed actual detuning happening in one ear only two or three times since I've passed my mid 20s. the second time, I tested it with earbuds - I had my PC play a sine wave at 440, sounded fine in the left but was very flat in the right, by easily 10 to 15 Hz. listening to anything with any kind of harmonic content with both ears was, obviously, terrible. nausea inducing, actually.
it goes away after 30 mins or so but the first time I had a brief moment of panic that this was some kind of permanent effect I had woken up with.
if my memory has any accuracy (dubious) then I was suffering from fairly heavy head colds every time this happened, so - applying totally uneducated guesswork - I put it down to something like uneven pressure buildup from a stuffy nasal cavity dampening the vibrations inside the ear.
