I gave high marks to the original
Wireless Bluetooth channels stream music to each device powered by 16 watts of audio juice, and the company's legacy "bass reflex system" in the back keeps the low frequencies nice and smooth.
SuperTooth rates the battery life at 3-4 hours if you're playing music nonstop at the highest maximum volume, but who does that? Realistically, you'll probably get about 10 hours of music at "normal volumes."
SuperTooth will also use the show floor to show off the HD-Voice, a new speakerphone for cars that that clips to the sun visor and lets you make hands-free calls using the same Bluetooth wireless streaming technology.
Of course, the device cares the most about keeping your hands free to operate the vehicle, so the speakerphone can also dictate text messages, announce incoming callers in 12 languages, and read the battery level and connection status aloud.
The Disco Twin will sell for $199 for both speakers in one box, and the HD-Voice will sell for $89 following the announcement at the show.
