Performance and Safety Tips
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.
This decibel (dB) table compares some common sounds
and shows how they rank in potential harm to hearing.
