DESC: These headphones have a whole new approach to high quality headphone design that's established a whole new look on the street. These are ideal for use with all Sony Walkman personal stereo players or anything you want to get the most sound from. Especially with Sony's Acoustic Turbo Circuit that enables these lightweight headphones to pump out big, heavy bass. You want that big, bass sound from your portable system? You can strap a couple of fat woofers to your head (not very stylish), or slip on a pair of Street Style headphones and jam on.
