LAS VEGAS--At CES Unveiled today, the Canadian audio company, Matrix Audio, demoed its newest (and smallest) member of its family of portable speakers.

Known as Qube, the $49.99 speaker measures 1.5 by 1.5 inches and is about the size of a golf ball. It connects to devices through an auxiliary cord that plugs into any 3.5mm headphone jack.

With its aluminum finish and polished colors, Qube sports an attractively compact design. Currently, it comes in black, silver, and red, but will come in three more pastel colors at the end of February.

The speaker will be available for shipping at the end of January, and a wireless Bluetooth version is slated for March.

During my time demoing the product, I was surprised by its big sound given its size. While audio did sound a bit harsh when it came to deep bass, it handled midrange volume well.
