At just 14mm thin, the W580 is offered in two colors—Style White or Urban Grey both with orange accents. The W580 also has light effects along the side that change as you navigate the music player. The W580 also features a 2.0 megapixel camera and has a 2-inch color display.
The phone also offers radio programming as it's equipped with an RDS-FM radio. The W580 ships with a 512 MB Memory Stick Micro. Memory can be upgraded. With regards to music, this Walkman model also has the Trackid application for recognizing music using GPRS. Sports-wise functions include applications to track your steps, your calories and monitor your running speed/distance/time.
The W580 can be coupled with Sony Ericsson's Portable Speakers MPS-70 and Snap-on Speakers MPS-75 or the Bluetooth Music Receiver MBR-100 that allows you to play music directly through a home stereo. The phone can be used as a remote control for this accessory to change tracks and increase volume.
