Key Music Features Walkman ® Player Using W200’s Walkman ® player couldn’t be easier: Press the Walkman ® key on the W200’s left side to go to the Walkman ® Player Now Playing screen. Play or pause the current track by pressing the left soft key. Use the navigation key to scroll through tracks of the selected album or playlist. (You can also use the volume keys to change tracks.) If you want to back out of the Now Playing screen to view all your albums, artists or playlists, simply press the Back key. Stereo Portable Handsfree with Bass Reflex Quality headphones are part of the Sony Ericsson Walkman ® experience, and the W200 is no exception. The stereo handsfree included with the W200 uses Bass Reflex, which works to maintain audio quality even when you crank up the bass on the W200’s equalizer. (To use the equalizer, select More > Equalizer from the Now Playing screen.)
