Cingular Go Phone: Blueant S4 Bluetooth Stereo Speaker Review

Works great, easy to set up. The sound is awesome and very clear. Small, thin and very portable. All voice controlled. I do miss the British female voice of my last Blueant speakerphone, this one has only an American male voice.
Must have only Windows 32 bit to update the software. Does not work with iMac (which I don't like.) You will also need FroYo 2.2 to use with Android phones.

Product Description:
The BlueAnt's most interesting feature is its hands-free trigger mode. While in trigger mode, a green LED is illuminated to indicate that the BlueAnt is listening for its activation phrase, "BlueAnt, speak to me." When the device hears this phrase spoken, it goes into listen mode and becomes responsive to its full list of voice commands. Users can ask the BlueAnt for information about its pairing state, update the phone book from a paired handset, check battery status, or query the S4 for a list of available commands.Of course, users can also make hands-free phone calls. Incoming calls can be answered or rejected by saying "answer" or "reject." If, during pairing, you allowed the BlueAnt to upload your phone's address book, incoming callers will be announced by name.Interestingly, the BlueAnt S4 doesn't seem to have its own internal voice dialing system, instead deferring calling duties to your paired phone's voice dialing system, if available. Outgoing calls are initiated by saying, "BlueAnt, speak to me" then "Phone commands" to access your paired phone's voice command system. If your phone doesn't allow access to external voice commands, as is the case with Android phones, then you're out of luck and will need to initiate your calls from your handset. This is more of a limitation of the paired phone than that of the BlueAnt S4 itself, but other systems like Ford Sync or Kia's OEM hands-free system get around this hurdle by running their own voice dialing software.In addition to hands-free calling, the BlueAnt S4 also supports A2DP audio streaming for listening to music or receiving turn-by-turn directions from a running GPS application. The unit also supports multipoint pairing for connecting to two devices simultaneously. When connected to two phones, the S4 can receive calls from either handset, but can only stream A2DP audio from the primary phone.
