1. Check whether the headphones are plugged in correctly, make sure to plug in the motherboard audio interface or replace the USB port; 2. Make sure the headphones are the default playback device; 3. Update or reinstall the audio driver; 4. Enable the disabled audio device. When Windows does not recognize headphones, you should first check whether the headphones are plugged in, try changing the jack, then confirm that the headphones are the default playback device in the sound settings, then update or reinstall the audio driver through the Device Manager, and enable the device that may be disabled in the sound control panel. If the problem is, there may still be hardware failure.
The problem of Windows not recognizing headphones is actually quite common, especially when there is no sound or the system does not respond after plugging in the headphones. This problem may be related to the driver, setup, or the hardware itself, but it can be solved in most cases.

Check if the headset is plugged in or try changing the jack
This is the easiest step to ignore. Sometimes the headset is not plugged tightly or the interface is inserted in the wrong way, and Windows will naturally not detect it. Confirm:

- Is the headset completely plugged into the audio interface (usually a green or pink 3.5mm jack)
- If it is a desktop computer, the jacks on the front panel and the rear motherboard sometimes have different functions. You can try changing to the jack on the back of the motherboard
- If you have USB headsets or headsets, try changing to USB mouth
Some laptops have loose jacks, which will disconnect if they sway slightly. You can also gently adjust the position of the headphone plug to see if there is any response.
Check sound settings and default devices
Even if the headset is plugged in, Windows may not set it as the default playback device. You can check this way:

- Find the volume icon in the lower right corner of the taskbar, right-click → "Open Sound Settings"
- Click "Sound Control Panel" (in "Related Settings")
- In the Play tab, check if your headset device appears (such as "Speaker/Earphones" or "Realtek High Definition Audio")
- If so, right-click to select "Set as default device"
If you don't see the headphone device, it may be a driver problem, read down.
Update or reinstall the audio driver
Many headphone recognition problems are actually caused by drivers. You can update the driver in the following ways:
- Press
Win X
and select Device Manager - Expand "Sound, Video, and Game Controllers"
- Right-click on Realtek, Conexant or other branded audio devices inside → select "Update Driver"
- If the update is invalid, you can try "Uninstall the device" and then restart the computer, and the system will automatically reinstall
If you are not sure which driver is audio-related, you can also directly search the official driver page of your computer model to download the latest version.
Enable disabled audio devices (hidden devices)
Sometimes Windows will misjudge the headset as a microphone, or the headset device is hidden by the system. This can be done at this time:
- Open the Sound Control Panel → Play tab
- Right-click the blank space → check "Show disabled devices"
- Check if there are any headphone devices displayed in gray. If there are, right-click → “Enable”
In addition, you can also do similar operations in the "Record" tab to ensure that the microphone part is fine.
Basically these are the methods. Most of the time, try it in sequence to solve the problem. If it still doesn't work, it may be that the headset is broken or there is a problem with the motherboard audio interface. You can use other headsets to test it.
