Sony NW-S703F (1 GB) MP3 Player

Active noise cancellation reduces ambient noise through a special phase canceling process. The Clear Stereo and Clear Bass features refine every note you hear by reducing audio leakage from one channel to another. Boasting a shape and 13.5mm drivers, you'll experience exceptional sound quality and comfortable fit from the noise canceling headphones. A high sensitivity microphone is built into the buds of the headphones enabling a wide-range frequency, dynamic range playback and powerful bass sound.
