When you are listening to music using the by-packed earphone, check on the color of the SafeSound icon on the top-right corner of the display.

Different colors of the SafeSound icon denote different current level of sound pressure:

: The current level of sound pressure is more than 90 decibels. It is recommended that duration at this level is less than 30 minutes a day.
: The current level of sound pressure is between 85 and 90 decibels. It is recommended that duration at this level is less than 2 hours a day.
: The current level of sound pressure is between 80 and 85 decibels. It is recommended that duration at this level is less than 5 hours a day.

According to the result of SafeSound monitoring, have a break or change the volume level for healthy hearing.
