3.Adjust the VOLUME as needed. Listening Safely

Do not listen at extremely high volume levels, especially using an earphone. Extended high-volume listening can lead to permanent hearing loss.

Always start by setting the lowest volume level possible first, then gradually increase the volume as necessary.

Once you set the volume, do not increase it. Over a period of time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.
