Gallic Bluetooth audio house SuperTooth wants you to buy its Disco speakers in pairs to better show off its stereo prowess, not to mention make a little more cash. That's why it's outing the Disco Twin here at CES, a $199 pair of noisyboxes that offer discrete left and right stereo -- each pumping out 16 watts of RMS power. You'll be able to squeeze up to four hours of juice out of each one if you use them to host a (short) rave, or up to 10 hours in more serene circumstances. At the same time, it's also releasing the HD Voice, an $89 hands-free car kit that clips to your sun visor and will even pair with your phone using voice commands. The company isn't ready to say when the pair will be available, but we can't imagine it'll be a long wait.
