Samsung Shape M3 speaker is a compact noise-maker (pictures)

Samsung's Shape M3 speaker is the smallest addition to Samsung's multi-room speaker system yet.

The smaller M3 is cheaper than the M5 or M7, but will sync up with its bigger brothers to fill your house with noise. You can stand it up as in the previous picture, or lie it flat.

The controls on the M3 are minimal -- you'll be doing most of your playback control from the Wireless Audio Multiroom app. That app works with a number of music services including Amazon Cloud Player, Pandora, Spotify, Rhapsody and TuneIn Radio.

The M3 looks good -- we particularly like this pleasant design over the grille.

Here's a snap of the inputs on the back. There's an Ethernet port, but the M3 should also connect over Wi-Fi.

That's the M3 on the right, next to the larger M5 and M7. As you can see, it's a lot smaller.
