I have two headphones, neither has any amps or volume control, and both have the same problem with this computer. I normally have the volume on 10%, and that is optimal. I'm still very afraid that someday it will be at 100% and i'll accidentally have my headphones on.
I tested how loud it is at maximum volume -- it's earsplittingly loud! In fact, it's so loud that if I lay the headphones down on the table, I can listen to a song perfectly clearly from meters away.
Is there any way to make the volume control more safe for the ears?
