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.
