My cousin and I were watching videos on Youtube on the highest volume (I also have really terrible speakers) and when we paused it, it would make this really high pitched screeching. No joke. Our ears hurt because the frequency was /way/ too high.
Then sometimes, the sound wouldn't work at all. I looked it up online and got: Check your sound -_- Like that's not the first thing someone would do.
And yet another problem that happens. Echoing audio. (if you've played online or used a phone and you hear the echoing of your own voice. Except it's not mine. It's the video's.). This is actually a constant problem if I have the volume on its highest then when I pause it, it'll make that high pitched screeching.
This is my second post. I'm sorry if I can't really get into detail much.

It hurt your ears because the SPL (sound pressure level - volume) was too high. Unless really durable headphones, it takes special speakers to reproduce high frequencies (above 20,000Hz) audio at high enough volumes to cause pain - and that would be very bad as ear damage is cumulative - that is, every time you subject your ears to high SPLs from music, jet noise, etc., some damage occurs and that damage builds and builds resulting in hearing loss as you age at much faster rate than those ears that were not subjected to such high SPLs.
