Stylish in design, easy to use and with no installation requirements, the BlueAnt Supertooth Light offers a safe alternative to talking on your phone while driving. The BlueAnt Supertooth Light uses a Digital Signal Processor (DSP) to remove any echo or background noise, resulting in extremely high sound quality of the user's voice regardless of whether the car is stationery or traveling at high speed. It also adjusts sound levels to compensate for loud engine noise or external noise created when the windows are wound down.Other products from A4C
