Fix: Wired headset microphone not working

A wired headset mic often fails because the plug is not fully inserted, the device has separate headphone and mic jacks, the headset needs a splitter, or the app is using the wrong input.

Quick answer

Push the plug in fully, check whether your device needs a headset splitter, then select the headset microphone as input.

Important warning

A 3.5mm headset with one combined plug may need a splitter on desktop PCs with separate headphone and microphone ports.

Try this

  1. 1 Check whether the headset has a mute switch on the cable.
  2. 2 Unplug and firmly reconnect the headset plug.
  3. 3 Make sure the plug is fully inserted.
  4. 4 Check whether your computer has separate headphone and microphone jacks.
  5. 5 Use a headset splitter if the headset has one combined plug but the computer has separate jacks.
  6. 6 Open sound settings and select the headset microphone as input.
  7. 7 Test the headset microphone in another app.
  8. 8 Try the headset on another phone or computer.
