Samsung YP-S2 Pebble, $39.99

It's not a pendant, but this tiny (0.65 x 1.62 x 1.66 inch) 1GB MP3 pebble-shaped player does hang around your neck rather attractively with earbuds attached to a lanyard. Supported audio formats further include WMA and OGG, while an LED on the bottom edge flashes different colors based on the playback mode to boot, also a nice, fashionable touch. (Check Price)
