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 cell phones, 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.
