Safety
Before using the earphones, turn the volume down. Once you have done this, turn it up slowly until reaching the
desired level.
Avoid noisy environments that force you to turn the volume really high when using your earphones.
Listening to loud music over a long period of time may cause your ears to get used to high volume levels,
resulting in irreversible hearing loss.
Adjust the volume of your earphones to hear important external sounds.
