A
Important Monster® 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 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. Refer
to the chart* below.
This decibel (dB) table compares some common sounds and
shows how they rank in potential harm to hearing.
