Sony Walkman NWZ-B143F: Tiny MP3 Player


Excellent audio quality and good battery life

Small form factor, built-in USB connection, easy UI navigation, voice recorder, good audio quality, good battery life, inexpensive

No built-in clip to attach to clothes, no AAC format support, UI can be a bit sluggish, bass mode reduces battery life significantly, slow data transfer speeds
