First make sure the headset is connected correctly to the computer.

• Without the adapter; when your computer has a combined audio port.
• With the adapter; if your computer has 2 separate audio ports.

Then make sure that both the headset and the microphone are selected as the default audio device (input and output) on the computer.

We recommend to check the following:

• Microphone privacy settings: Check if the microphone allows apps to access the microphone
• Default device: Check if the microphone has been selected as the default sound input device on the computer
• Windows Update: Check if Windows is up-to-date via windowsupdate.com

Try the product on another device, does the microphone function on another device?
