The scala-700 headset offers the best of all worlds: lightweight and stylish yet feature-rich and user friendly. It includes all of the advanced features one would expect in a Bluetooth headset such as voice dial and re-dial call waiting conference calling call reject and wind and noise reduction plus unique features that set it apart from other headsets.Toggle between two active phones: SWAP Technology allows users to easily switch the headset's connection between paired mobile phones at the touch of a button.As wireless headsets become smaller the more comfortable and natural they are to wear. But small items often get lost among the clutter of an office in a desk or in clothing. So a buzzing locator device was added. Users need only to press a button on their mobile phones to activate the locator which initiates a series of audible tones from the headset until it has been found.Just like a mobile phone a wireless headset too should indicate its charging status. The scala-700 does just that: with a press of a button the scala-700's LEDs instantly display whether it's fully charged (blue) half charged (blue and red) or in immediate need for recharging (red).The scala-700 not only delivers a rich feature set but offers extremely clear audio even under noisy background conditions. The device's six-level volume range speaker booster and echo-cancellation technology further enhance the headset's superb audio quality.
