• Put the headphones on, and then gradually
increase the volume to your desired listening
level.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to
permanent hearing loss.
• Once you set the volume, do not increase it.
Over time, your ears adapt to the volume level,
so a volume level that does not cause
discomfort might still damage your hearing.
