Summary: The BlueAnt S4 delivers good call quality and, with its voice trigger system, increased vehicle safety. However, it excludes many popular handsets from its true hands-free claim by not including its own voice dialer.
Pros: The S4's voice trigger grants users access to most of the speakerphone's functions without physically touching the device. "What can I say?" command practically eliminates the need for an instruction manual. Imported contacts' caller ID info is read aloud when receiving a call. Bing-411, Vlingo, and BlueAnt app integration, as well as A2DP audio streaming, extend the device's functionality.
Cons: The S4 lacks a built-in voice dialer, so if the paired phone doesn't have its own voice dial system (e.g. Android), calls must be manually initiated. In louder vehicles, the S4 had difficulty understanding our voice commands.
Excerpt: The BlueAnt S4 True Handsfree Voice Controlled car speakerphone has become my travel companion in my weekly rental cars. Most states have adopted hands-free laws, and the BlueAnt S4 helps you comply with local laws and it makes you a […]
Summary: The BlueAnt S4 can be put into pairing mode with the button, but it is much easier to say "BlueAnt Speak To Me" and then "Pair Me" instead of remembering how long to hold what button. Once pairing mode has been entered, you can pair the S4 with up to 8 devices - and remain connected to two devices at once. This is true multi-point and although it seems like it could get a little confusing, it seems to work and balance well.
Pros: True Hands-free calling, answer and text, Voice Activated Answer means you don't have to take your hands off the wheel to answer a call, Voice Prompts, Text To Speech announces callers name if it's in your address book (just number otherwise), Pair with up to 8 devices, Good range
Cons: Mic quality isn't as good as a headset, Speaker isn't quite loud enough in noisy driving environments
