actually are. Use only compatible earbuds, headphones, or earpieces with your MacBook Pro.
Turn on the audio and check the volume before inserting anything into your ear. For more
information about hearing loss, see www.apple.com/sound.
WARNING: To prevent possible hearing damage, do not listen at high volume levels for
long periods.

device, stop using MacBook Pro.
