BlueAnt introduced a new visor-mount speakerphone at CTIA 2009, called the BlueAnt S1. Designed to work in the car, it has pretty much the same features as the , except it has support for A2DP. That means you can stream music wirelessly to it from a device that has stereo Bluetooth. It's not really meant as a stereo speaker system though, so don't expect it to replace your expensive car stereo.
Like the other BlueAnt devices, the S1 lets you use your voice to make and answer calls. It also has multipoint, which means it can connect with up to two different devices at the same time, and it has background noise reduction too. However, unlike the Supertooth 3, it doesn't have a text-to-speech feature that will read out incoming caller ID. The BlueAnt S1 will be available later this year around June or July for $79 each.
