Before using your Microsoft® LifeChat headset, connect it to a powered USB port.
Using a wired headset
Before you put on a headset for the first time, lower the volume.
Put on and position the headset.
Adjust the microphone. Position the microphone’s flexible arm so that the microphone is approximately one inch (3 centimetres) from your mouth. Move the arm to one side of your mouth to prevent transmitting the sound of your breath while you are on a call.
