Are Earphones Damaging Your Ears?

Earbud headphones are typically inserted into the ear and deliver sound directly into the ear canal. Based on recommendations from a study conducted through Harvard Medical School, safe listening limits are only about 1 1/2 hours per day with the volume control set at 80% of maximum. Many people spend three, six or even eight hours per day listening and at generally higher volumes. There is growing concern that this could permanently damage your hearing.
