Important Safety Information

Listen Responsibly
To avoid hearing damage, make sure that the volume on your music player is
turned down before connecting your headphones. After placing headphones
in your ears, gradually turn up the volume until you reach a comfortable
listening level. Noise levels are measured in decibels (dB); exposure to any
noise at or above 85 dB can cause gradual hearing loss. Monitor your use;
hearing loss is a function of loudness versus time. The louder it is, the less time
you can be exposed to it. The softer it is, the more time you can listen to it.
