BusinessWeek.com has Rated Scala 700 Best! 5 of 5 stars.

Multi-Pairing capability: allows users to easily switch the headset’s connection between 2 paired cell phones at the touch of a button. Location Buzzer: 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, Cardo added a buzzing locator device. Users need only to press a button on their cell phone to activate the locator, which initiates a series of audible tones from the headset until it has been found. Battery Status LEDs: just like a cell phone, a wireless headset should also indicate its charging status. The Scala 700 does just that: with a press of a button, the Scala 700 LED instantly displays whether it’s fully charged (blue), half charged (blue and red) or in immediate need of recharging (red). Wind and Noise Cancellation: the Scala 700 not only delivers a rich feature set, but offers extremely clear audio, even under windy or noisy background conditions. The device’s six-level volume range, speaker amplifier and echo-cancellation technology further enhance the headset’s superb audio quality.
