> Always make sure that the sound output coming out of your headphones is set at a moderate volume. What exactly does "moderate" mean? You should be able to hear someone nearby if they call out to you.
> Pay special attention to the volume level when you're listening to music, especially music that's especially percussion- or bass-heavy. This kind of music can cause serious hearing damage if played in headphones at excessive volume.
> If possible, avoid "ear buds" or other headphone styles that penetrate inside the ear. Instead, choose headphones that rest on top of the ears. This style is less obtrusive and less likely to cause hearing damage.
> It's not a good idea to use ordinary headphones while on airplanes, trains, or while you're near loud machinery. Such environments contain a high level of ambient noise and will incite you to turn your volume up to dangerously high levels without even noticing it. If you must use headphones in such situations, use the "noise canceling" type.
> Use headphones in moderation. Even if you are listening only to the spoken word (such as a talk radio station or an audiobook) try not to use your headphones for more than 90 minutes a day.
