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.
