When your headphones stop working with your iPhone 16, it can feel like a sudden audio blackout. Whether you're using the USB-C port for wired buds or connecting to AirPods over Bluetooth, the fixes are usually straightforward. I'd start by checking a few simple things first.
Restart Your iPhone 16
This is often the quickest fix for any weird audio glitch. To restart your iPhone 16, press and quickly release the Volume Up button, press and quickly release the Volume Down button, then press and hold the Side button until you see the Apple logo appear. This force restart can clear out temporary software bugs that are blocking your headphones.
Check the Physical Connection
For wired headphones, make sure the USB-C plug is fully inserted into the port. A loose connection is a common culprit. If you're using Bluetooth headphones, ensure they're charged and in pairing mode. It's always a good idea to test the headphones with another device to rule out a hardware failure on their end.
Clean the USB-C Port
Lint and pocket debris love to get packed into the USB-C port on the iPhone 16, which can prevent a wired headphone adapter from making proper contact. Use a dry, soft-bristled brush or a wooden toothpick to gently clean out the port. Avoid using metal objects, as they can damage the sensitive pins inside.
Verify the Audio Output
Sometimes your iPhone 16 sends audio to the wrong place. Open Control Center, then press and hold the volume slider in the top-right corner. A menu will pop up showing all available audio outputs. Make sure your headphones are selected here, not the iPhone speaker or another Bluetooth device.
Forget and Re-Pair Your Bluetooth Headphones
If your wireless headphones are connected but there's no sound, the pairing profile might be corrupted. Go to Settings > Bluetooth, tap the info icon (i) next to your headphones, and select Forget This Device. Then, put your headphones back into pairing mode and reconnect them fresh from the Bluetooth menu.
Update to the Latest iOS
Audio and Bluetooth issues are frequently addressed in software updates. Head to Settings > General > Software Update to check for and install any available updates for iOS 26. This is particularly important for ensuring compatibility with newer headphone models and firmware.
Check for Software Volume Limits
Press the Volume Up button on the side of your iPhone 16 while your headphones are connected. Also, make sure you haven't accidentally enabled a volume limit. Go to Settings > Sounds & Haptics > Headphone Safety to check if "Reduce Loud Sounds" is turned on and set to a very low level.
Reset All Settings
For persistent problems where audio consistently routes to the wrong output, a settings reset can help. This won't delete your data, but it will clear all your preferences. Navigate to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. You'll need to re-pair Bluetooth devices and reconfigure things like Wi-Fi passwords afterward.
