SafeSound
With the earphones, SafeSound allows you to listen to music in a safe way.
When you listen to music through the earphones, the sound pressure on your ears is estimated¹ based on the electrical characteristics of the player and earphones.
Then, the estimate is compared against the reference levels² of sound pressure. As a result, icons of different colors can be displayed to indicate status of sound pressure and the levels of risks to hearing damage.
