Own the streets wearing a set of headphones with cred. The CX 280 delivers slamming bass with a custom fit that feels and looks natural with any gear. These ear-canal noise-isolating 'phones use a dynamic speaker for deep tight bass. If you need to travel light they include a carrying case that will hold the headphones in addition to the latest generation of iPod Nano media players. Even better you can keep the player in your pocket and still control playback volume with the included in-line adjuster. Total control.
