A person wearing headphones can hear what no-one else
does. But sometimes a person wearing headphones also
wants to hear the outside world - the headphones are so that
others do not need to listen to ones private music.
These headphones have exterior microphones, so in addition
to hearing
your music you can hear what is going on in your
environment.
