1) Check the headset cable controls to make sure that the mic is switched on.
2) Determine whether your computer has a single audio/mic input or if it has 2 separate audio/mic input slots. If it only has a single input, connect the 3.5mm jack of the headset directly into the slot. If it requires 2 separate inputs, connect the 3.5mm jack to the splitter cable (comes with the headset package), then connect the headphone jack and microphone jack on the splitter cable to the correct input slots on your computer.
3) Once the headset is connected, check if a dialogue box appears on your computer asking you to select a device. Select "headset" if prompted to. Skip to step 4 if no dialogue box appears.
4) Go to your computer’s Control Panel, then double click “Sound”.
5) Under the recording tab, you should see a green check mark next to “Microphone Realtek High Definition Audio.” Click on the microphone and select “Properties” at the bottom right-hand corner of the screen.
6) Under Properties, select the “Levels” tab. Make sure the volume level of the microphone is turned all the way up. Then click OK to exit the screen. Control your headset volume as you would with any standard set of headphones or earbuds.
