* A decibel (dB) is a unit of relative measurement of the strength of sound wave. In decibels (dB), a
measured signal level doubles with every additional 3 dB.
# These sound decibel levels are considered harmful under extended exposure.

For your safety!
Your hearing may adapt to higher volumes of sound. In order to prevent any harmful impact to your
hearing, you must control the sound emanating from your headphones and set the media player volume
to a low setting where you can hear it clearly and comfortably.
Studies, including one from NIDCD indicate that sounds of less than 80 decibels, even after long
exposure, are unlikely to cause a hearing loss. Listen to your media player at such a level that you can
still hear conversation and other people in your environment without shouting when you attempt to
converse.
It can also be dangerous to play your music with headphones/earphones at high volume while walking,
or engaged in other activities. You should exercise extreme caution and discontinue use in potentially
hazardous situations.
Do not use headphones/earphones while driving, cycling, or operating any motorized vehicle. This may
create a traffic hazard and may be illegal in some areas.
