This Jabra SPEAK 510 MS -USB VoIP desktop hands-free unit is perfect for online video conferencing.
The device contains a USB 2.0 cable that connects to any computer's USB 2.0 port.
The first time the Jabra plugs into a computer, it will automatically install necessary drivers. Do not unplug the Jabra during this installation process. When video conferencing, make sure to set the video conferencing software's audio input/output to the Jabra rather than your computer's built-in input/output.
