Plantronics latest addition to the Bluetooth speakerphone market is the K100. The K100 is a slim, low profile speaker that slides on to your car's sun visor to allow hands free operation of your Windows Phone.
Not everyone is comfortable with a Bluetooth headset and the K100 gives drivers a hands-free alternative. Additionally, the K100 provides an FM transmitter that allows you to stream audio files from your Windows Phone through your car stereo.
To see if the K100 is worth the investment, make the jump past the break.
