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/on 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.
