[. . . ] Over time your hearing "comfort level" adapts to higher volumes of sound. So after prolonged listening, what sounds "normal" can actually be loud and harmful to your hearing. To guard against this, set your volume to a safe level before your hearing adapts and leave it there. [. . . ] To establish a safe volume level: Set your volume control at a low setting. Slowly increase the sound until you can hear it comfortably and clearly, without distortion. Listen for reasonable periods of time: Prolonged exposure to sound, even at normally "safe" levels, can also cause hearing loss. Be sure to observe the following guidelines when using your headphones. Do not turn up the volume so high that you can't hear what's around you. You should use caution or temporarily discontinue use in potentially hazardous situations. Do not use headphones while operating a motorized vehicle, cycling, skateboarding, etc. ; it may create a traffic hazard and is illegal in many areas.
