I'm starting a new series called Biz Gadgets, where I will be reviewing electronics suited for the small business owner. This week let's take a look at the Supertooth 3 from BlueAnt.

Handsfree devices have become popular in recent years, especially with drivers. States like New York and California now have laws preventing handheld mobile phone use while driving. (look up your state) There is debate whether or not handsfree devices truly make driving safer. Safety really depends on the particular device (is it truly handsfree?) and the behavior of the driver.

When looking for a handsfree device for my car, I decided on opting for a speakerphone as opposed to an earpiece. I find earpieces too cumbersome. They make us look funny too, like cyborgs. Most earpieces should be labeled partially handsfree because they require pressing a button when answering calls. I don't want to have to press any buttons when driving, making the speakerphone my best option. After sifting through reviews and surveying friends, the Supertooth 3 became the clear choice for the features and price I wanted.

The Supertooth 3 is a speakerphone that connects wirelessly with your mobile phone via bluetooth. It is designed for the car, giving you a handsfree solution when you're driving. The Supertooth 3 automatically connects to your phone upon entering the vehicle. When a call comes in, you have the option of accepting or rejecting the call by speaking simple voice commands, or by pressing the appropriate button.

The Supertooth 3 allows you to upload your phone's address book (confirm compatibility) and uses the information to announce who is calling. Calls are announced using BluAnt's sophisticated Text-to-Speech technology, which can be set to 6 different languages.

I am very pleased with the audio quality. People on the other end seem to agree. The volume level has been satisfactory in my experience. On a good connection the audio level is enough so that I can hear the caller when the windows are down.

Battery life is impressive. I can easily go 4 weeks without needing to recharge. I don't talk very much in the car, so this number will differ depending on your usage. The Supertooth 3 comes with two sun-visor clips, allowing you to easily transition between two vehicles.

I'm using the Supertooth 3 with my iPhone and they seem to play well together. Periodically updating my address book has been a breeze. I've used it in the office a few times for conference calls. It really is a great little speaker phone.
