The controls are housed on the back side and are indented in a bowl shape, which gives them a nice feel. A central play/pause/power key--the only bit of silver on the device--is surrounded by track shuttle and volume buttons. Jutting out from the bottom right of the control pad is a smart key.
Has Samsung made a rock? No, the S2 Pebble is just a cleverly designed MP3 player made to look like a smooth, polished stone. In fact, it looks like the perfect skipping stone, with its flat, nearly circular shape and 1.5-inch diameter.
From the front, the S2 still doesn't look like an MP3 player. The only thing indicating its electronic capabilities is the glowing LED, which changes colors to indicate different modes and selections. (The bottom of the player is pointing up in this shot.)
The design of the S2 lends itself to being worn. The fact that the front has no controls makes it look more like an actual pendant than many other wearable MP3 players. The included headphones are predictably lanyard style.
