Features of the Bose QuietComfort Series

When Bose designed the QuietComfort headphones they outdid themselves.  Their unique design and innovative approach made these headphones the must have for travelers and music enthusiasts. 
Some of the features include:

Microphones both inside and outside each earcup to sense and reduce more of the sounds around you. 

A Tri-Port structure, which enables a tonally-balanced audio performance—including reproduction of deep, low notes—from relatively small and lightweight headphones.

Active equalization, that tunes the headphones' frequency response, enabling outstanding audio performance.

A Single, detachable audio cable that offers greater convenience than standard Y-cables.  (I love this, no tangling)

Folding flat earcups that rotate 90 degrees for easy storage and portability in the included case, all stored in a carrying case helping to protect the headphone and any accessories during travel.

This is all surrounded by Bose redesigned ear cushions that uses new materials to establish a critical acoustical seal—helping to further reduce noise while providing a comfortable fit.

Plug it in to your IPod, home PC or use them to silence the noise around you!  You'll forget that their even on your head.
