Question

If you turn your volume to loud on u'r headphones can it break the sound quality of the speaker?

Answer 1

Yes, it is possible to "blow the speaker" in your headphones by listening to loud music (such as high BPM stuff, like extratone or extremely bass-ey stuff)

Answer 2

Yes. It can even overload the speakers and cause ear damage. One of my friends is practically deaf in one of her ears because the earbud exploded.
