Caution!: Avoid potential hearing loss.
Damage to hearing occurs when a person is exposed to loud sounds 
over time. The risk of hearing loss increases as sound is played 
louder and for longer durations. 
Prolonged exposure to loud sounds (including music) is the most 
common cause of preventable hearing loss. Some scientific research 
suggests that using portable audio devices, such as portable music 
players and cellular telephones, at high volume settings for long 
durations may lead to permanent noise-induced hearing loss. This 
includes the use of headphones (including headsets, earbuds, and 
Bluetooth or other wireless devices). Exposure to very loud sound has 
also been associated in some studies with tinnitus (a ringing in the 
ear), hypersensitivity to sound and distorted hearing.
Individual susceptibility to noise-induced hearing loss and potential 
hearing problem varies. Additionally, the amount of sound produced 
by a portable audio device varies depending on the nature of the 
sound, the device settings, and the headphones that are used. As a 
result, there is no single volume setting that is appropriate for 
everyone or for every combination of sound, settings and equipment. 
You should follow some commonsense recommendations when using 
any portable audio device:
