DESC: The noise cancellation headphones cancel noises that are around the user, while incorporating the LINK technology. This makes it possible for the user to listen to music without outside noises and take phone calls into their headphones. The headphones are ideal for anyone who looks to reduce office noise, commuter train chatter, airline engine sound, etc. The market for these headphones is anyone who wants to enjoy their music without having to hear the noises that are present around them all the while being able to answer cellphone calls hands free.
