I was bored so I hooked up the POS apple earbuds I have to my MAGNI/MODI setup and turned the volume up to 100% The earbuds had gratingly harsh highs that seemed to nearly damage the drivers. Anyway, I want to know what exactly is happening science-wise when one uses earbuds with an amp at maximum volume. Is this bad at all for the amp?
Using earbuds with amplifier; what happens? (random curious question)

A proper headphone amp shouldn't care at all. If you stress an amp for a long time then in some amps the parts can heat up to a point where they will eventually fail.
1) the driver doesn't produce any sound anymore because the voice coil "blew out" like a fuse
2) the strong movement and exceeding the excursion limit destroyed the driver's surround and/or diaphragm - sound will be bass-light and distorted, there could even be mechanical damage done to the voice coil
