The Supertooth 3 features a choice of 6 languages including American English, Spanish, French, Italian, German and British English
The Supertooth 3 can be paired with up to 8 devices and supports voice dial activation, redial and call reject.
The Supertooth 3 also adjusts sound levels to compensate for loud engine noise or external noise created when the windows are wound down.
The Supertooth 3 announces the name or ID of the caller by using text-to-speech technology. When the phone rings, users just say 'OK' to accept the call.
Voice prompts provide assistance to help you connect the device with your phone and upload your address book.
The device is quickly and easily installed and connected to your mobile phone. Simply slide the metal clip onto your sun-visor and attach the Supertooth 3 via the magnets on the rear of the device.
The BlueAnt Supertooth 3 hands-free speakerphone provides a safer, legal alternative to talking on your mobile phone while you drive. The Supertooth 3 will be available in Telstra stores from June 2 and available at other retailers Australia-wide in mid to late June.
Its audio quality is a result of using advanced digital signal processing software to eliminate noise and achieve echo cancellation, regardless of whether the car is stationary or travelling at high speed.
