Steps
Unplug the headphones and plug them back in firmly until the connector seats fully. Remove any phone case or port cover that stops the plug going all the way in.
Test the headphones on another device, such as a laptop or Android phone. If they stay silent there too, the headphones are the problem, not the iPhone.
Shine a light into the USB-C port and look for lint, dust or fluff. Use a wooden toothpick to lift debris out gently. Never use a metal pin or any liquid.
Restart the iPhone. Hold the side button and a volume button, slide to power off, wait 30 seconds, then press the side button to turn it back on.
Update iOS. Open Settings, tap General, then Software Update, and install anything waiting there.
Turn Bluetooth off in Control Center so the iPhone stops sending audio to earbuds or a speaker you paired earlier.
Play a song, open Control Center and tap the AirPlay audio icon. Pick your USB-C headphones from the list if they appear there.
If you use a USB-C to 3.5 mm adapter or a hub, swap it for a known good one. Cheap adapters without a built-in audio chip often pass no sound.
Still nothing? Go to Settings, General, Transfer or Reset iPhone, then Reset, and choose Reset All Settings. This keeps your data but clears audio routing glitches.
Tips and common mistakes
Skip compressed air, as it can push lint deeper into the port.
Let a wet or damp port dry fully before plugging anything in, and never clean it with liquid.
Try Apple or brand-name USB-C earphones first, since some no-name models draw more power than the port allows.
Questions
Why does my iPhone say the accessory is not supported?
That message usually means the port has lint or moisture in it, or the accessory needs more power than the iPhone will supply. Clean and dry the port, then try a different pair of headphones.
Do USB-C headphones need a special chip for iPhone?
No. Standard USB-C audio headphones work, but cheap USB-C to 3.5 mm adapters need a built-in DAC chip. An adapter without one will often give no sound at all.
Will resetting my iPhone fix USB-C audio?
A full erase rarely helps. Reset All Settings is the safer first try, since it clears audio routing glitches without deleting your photos, apps or messages.
