Yamaha introduces its cube-shaped portable speaker--the Yamaha NX-A01--that measures just 3.5-inches on each side and connects to iPods and other audio players.

It features Swing Radiator Bass technology and easy to use controls located on the top of the unit to power, mute, and control volume. Its frequency response rate is said to be 90Hz to 20 kHz. If you purchase the optional Yamaha TRX-RO1BT adaptor ($129), then the NX-A01 can receive Bluetooth audio from cell phones or computers.

Comes with an AC adaptor and audio cable. It's so darn cute, isn't it? The Yamaha NX-A01 is available on AudioCubes.com for $129.
