SuperTooth (http://www.supertooth.net) is debuting the Disco2 portable speaker and the Crystal, a Bluetooth speakerphone, at this week's Consumer Electronics Show (CES) in Las Vegas.

The former is an US$99, portable, rechargeable speaker featuring an "avant-garde design" and compact footprint. Users can stream music wirelessly from any cell phone, tablet, computer or MP3 player supporting Bluetooth A2DP to a single or dueling pair of Disco2s, featuring new technology providing left speaker/right speaker functionality.

The Disco2 kicks out 16 watts RMS audio power, with 2-way stereo speakers and a dual high efficiency subwoofer and medium tweeters. It will be available in alternative colors later this quarter.

The $69 Crystal -- also due later this quarter -- will attach to a car’s sun visor via a durable, magnetic clip allowing for instant hands-free calling capability for any type of vehicle. Featuring automatic pairing and multi-point technology connecting up to 2 phones simultaneously, Crystal will purportedly provide up to 20 hours of hands-free talk time (40 days of stand-by) with a three-hour charge of its lithium-ion battery.

It will also stream music directly from all Bluetooth A2DP-enabled phones, as well as announce turn-by-turn navigation from a Bluetooth-enabled smartphone. Crystal also supports voice recognition dialing for phones equipped with this feature.
