So potentially you could use an iPod to fix the damage caused by an iPod.
Personally I choose not to use earbuds or even earphones because the dB level produced in the ear is far too high. I prefer headphones (on ear or over ear) with noise cancelling, I barely need the volume up to get the feeling of loudness as they better produce bass noises and the most damage done to our ears is typically by high-frequency noise that most people don't desire when listening to music.
