BlueAnt has released its latest Bluetooth Speakerphone, the S4. The S4's main features center around the use of voice commands to enhance the "hands free" experience. While you can still control the speakerphone with buttons, with the S4 you can say "answer" or "ignore" to manage incoming calls.
In addition to offering hands free calling, the S4 also puts BING information at your disposal through BING 411 and allows access to audible text messages by being Vlingo compatible. All in all, the S4 hopes to keep your hands more on the wheel and less on your phone.
We had the opportunity to take the S4 out for a test drive and found it to offer some "cool" features. We also found some features still needed a little work. Follow the break to what type of impression the S4 left.
