Adjust the volume knob on the speakers to about 3/4 of the way to maximum.

Some headsets include a microphone, if this is the case there will be two plugs at the end of your headset cable

The plugs on most headset cords have an 'icon' of a microphone and/or a speaker on each plug

Be sure your speaker plug is plugged into the speaker output of your computer
