Quick answer: turn Bluetooth off, check the headphones on another device, use the correct adapter (USB-C or Lightning) and clean the port. If the phone shows a headphone icon with nothing plugged in, the port has dirt or moisture in it.
Wired or USB-C headphones not working
- Turn Bluetooth off – sound may be going to another device.
- Test the headphones on another phone or laptop.
- Use the right adapter. Phones without a headphone jack need a USB-C or Lightning to 3.5mm adapter. Cheap “passive” USB-C adapters often don’t work – a USB-C adapter with a built-in DAC (digital-to-analogue converter) is more reliable.
- Push it in fully and take the case off – thick cases can stop the plug seating.
- Clean the port – see cleaning the charging port.
Phone stuck in headphone mode
Symptoms: no sound from the speaker, a headphone icon on screen, or volume labelled “Headphones” with nothing connected.
- Plug headphones in and out a few times, then restart.
- Check Bluetooth isn’t connected to something nearby.
- Look in the port with a torch for fluff or moisture and clean it.
- If it got wet, leave it to dry for 24 hours – moisture can trick the port into detecting a plug.
Still stuck?
A port that keeps detecting headphones usually has corrosion or damage inside. On phones without a headphone jack this is the charging port – a common, same-day repair.
