With Smart phones, we can always be connected and can consume media both Audio and video, almost all day without any interruption.
Generally, when people listen to music, its always with earphones plugged-into ears. A common use case is when commuting we always listen to music with earphones.
My Question is: How much music one should listen with plugged-in earphones in a day, without causing ear/organ damage? Looking for a general medical advice here for healthy ear functioning yet consuming favorite music?
