The Supertooth II is a wonderfully designed unit. The two magnets attach securely to one of the two included sun-visor clips. Noteworthy on this model is the large speaker and the flip down microphone.
The beauty of this design is that flipping down the microphone turns on the device and answers the calls. If the Microphone is kept in the "down" position, calls will automatically be answered when they come in. Your hands never have to leave the wheel - which is the idea behind "hands free" design.
There is a very easy to use volume control knob - a design I much prefer to up and down arrows. LED's show the Bluetooth connection and charge of the battery.
One extra detail is that the Supertooth II ships with a car charger and a home AC charger. In theory, you never need to take the Supertooth II out of your car to charge.
Ease of Use
The Supertooth II could not be easier to use. Pairing is accomplished by holding the call reject button and the Pick up button simultaneously. Lights flash, phone finds Supertooth, pass code entered and there you have it.
One of the nicest features of the BlueAnt experience is their wonderful user guides. Within the user guides are not only directions for pairing and using, but specific directions for virtually every mobile phone/smartphone on the market.
I so appreciated the subtle differences in directions for getting this to work flawlessly on my Treo. No manual has ever been more complete and helpful. BlueAnt obviously realizes that Bluetooth is still an evolving science and that some companies do it a bit differently.
Once paired, using the Supertooth II was a joy. The Mike can swivel into a usable position whether the visor is down or up (a nice touch). Calls came in perfectly. This is truly a “just set it up and use it” kind of device.
This is the single most important issue in a Handsfree car kit. If people can't hear or understand you - no matter how good the design - the car kit becomes useless. Well, BlueAnt has no worries in this department.
I routinely asked callers how I sounded. People said calls were clear and I sounded just like I was using the phone itself. Even with the windows down and the radio on, people were still able to hear me clearly.
Sound on my end was amazing. Calls were clear - no tinny sound, no reverberation - just crystal clear sound.
