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