For those who experienced the Yamaha NX-A01 speaker cube will agree that the lack of wireless capabilities was a sore point with the speakers. However with the new NX-B02, Yamaha seems to have rectified the error. Designed on the lines of the A01, the B02 features a stereo pair of 1.75-inch titanium cone drivers, a little fluttering bass port, a standard 3.5mm line-input, Bluetooth 2.0+EDR/A2DP, and the option of powering it with either an adapter or four AA batteries. Battery life is only about 4 hours, so that's a bummer.

The Yamaha NX-B02 is available now in red, black, or white, for around $199 and a street price hovering around $140.
