BlueAnt S4 Bluetooth Car Speakerphone
Product Review (submitted on October 3, 2011):
I have had the blue ant st3 for 2.5 years and it is a very good quality bluetooth speaker phone, works with out fail and the voice quality is almost excellent, i would say A- for voice quality.
I am sure the new one is better on voice quality from what i have learned, and no more pressing tthe green button to make a call, now all voice.
The next step blue ant needs to go to is getting the speaker phone to allow you to add a phone # by voice to your phone book, thats now in your cell yet, now thats total hands free and I will buy that one.
