If the iPhone headphones do not physically fit, the PC jack and the headphone plug are different connector types.
A standard wired headphone jack on many PCs is 3.5 mm. Windows guidance for audio troubleshooting also refers to 3.5 mm jacks and checking that the plug is inserted into the correct audio jack.
A simple way to check compatibility:
- Look at the PC audio port.
- If it is a round 3.5 mm jack, headphones with a 3.5 mm plug should fit.
- If the PC does not have a 3.5 mm jack but has USB-C, a Surface USB-C to 3.5mm Audio Adapter can connect standard 3.5 mm headphones.
- Check the headphone plug.
- If the iPhone headphones have a 3.5 mm plug, they should physically fit a 3.5 mm PC jack.
- If they have a different connector, they will not fit that jack.
- If using USB-C audio, use the right adapter type.
- Windows notes that many PCs support USB-C digital audio adapters, and an analog USB-C audio adapter might not work.
- If the plug fits but audio still does not work, check the basics:
- Make sure the cable is fully inserted.
- Try the correct audio output jack.
- Try a different USB port if using a USB audio device.
- Unplug other headphones or speakers and test again.
If the goal is to use wired iPhone headphones on a PC, the key thing to verify is whether the headphones end in a 3.5 mm plug. If not, an adapter or a different headset type is needed.
