Using Earphones

Turn down the volume before connecting the earphones. Slowly raise the
volume with the earphones on until you reach your desired volume. When
earphones are connected, the speaker is automatically muted.
Long-term exposure to loud music may cause hearing damage. It is best
to avoid extreme volume when using earphones, especially for extended
periods.
