If you just got an iPhone 15 and your headphones aren’t working, you’re not alone. Many users face this frustrating issue, and it can happen with both wired and wireless headphones. Sometimes, the problem is simple—a loose connection or a bit of dust. Other times, it’s a software glitch or a deeper hardware issue. The good news: most problems have simple solutions you can try at home before visiting a repair shop.
This guide explains the 15 most common reasons why your iPhone 15 headphones might not be working, and how to fix each one. We’ll also cover a few smart troubleshooting tips and answer the questions people ask most.
1. Headphones Not Properly Connected
Sometimes, the simplest answer is the right one. Make sure your headphones are plugged in fully or properly paired if they’re wireless. For wired headphones, push the connector until you hear or feel a click. With wireless headphones, check for a solid Bluetooth connection.
2. Bluetooth Not Enabled
If you’re using Bluetooth headphones, your iPhone 15’s Bluetooth must be turned on. Go to Settings > Bluetooth and make sure the switch is green. If your headphones aren’t listed, try pairing them again.

3. Headphones Not Compatible
Some older headphones may not work with iPhone 15, especially if they use outdated Bluetooth versions or lack support for Apple’s standards. Check your headphone specs or try them with another device to confirm compatibility.
4. Volume Too Low Or Muted
It’s easy to overlook the volume. Use the side buttons to turn up the sound. Also, check the volume slider in Control Center. Some headphones have their own volume controls—make sure they’re turned up too.
5. Headphones Not Selected As Output
IPhones can send sound to different devices. Swipe down for Control Center, tap the AirPlay icon, and choose your headphones as the audio output.
6. Headphone Jack Or Port Dirty
Dirt or lint can block connections. For wired headphones, carefully inspect the USB-C port. Use a toothpick or compressed air to remove debris. Avoid using anything metal, which could damage the port.
7. Headphones Need Charging
Wireless headphones won’t work if their battery is empty. Place them in their charging case or use a cable. Some models show battery status in the iPhone’s battery widget.
8. Software Glitch
A quick restart often fixes random software bugs. Hold the side and volume buttons until the power slider appears, then turn your phone off and on again.

9. Outdated Ios Version
Apple updates often fix audio bugs. Go to Settings > General > Software Update. If an update is available, install it and try your headphones again.
10. Bluetooth Interference
Other wireless devices nearby can interfere with your connection. Try moving to a different room, turning off unused Bluetooth devices, or resetting your headphones.
11. Headphones Not Paired Correctly
Some wireless headphones need to be in pairing mode before connecting. Refer to your headphone’s manual. On your iPhone, forget the device in Bluetooth settings, then pair again.
12. Audio Balance Settings
Go to Settings > Accessibility > Audio/Visual > Balance. If the slider isn’t centered, sound may only come through one ear. Adjust as needed.
13. App-specific Audio Issues
If headphones work in some apps but not others, check the app’s settings. Some apps have their own mute buttons or audio controls. Updating the app may also help.
14. Water Damage
Even though iPhone 15 is water-resistant, the headphone port or your headphones might not be. Signs of water damage include muffled sound or no sound at all. Let your devices dry completely before trying again.
15. Hardware Defect
If you’ve tried everything and your headphones still don’t work, there may be a hardware issue with your iPhone or headphones. Try using a different pair of headphones to isolate the problem. If nothing works, contact Apple Support.
Comparison Of Wired Vs Wireless Headphone Issues
Understanding the differences can save time when troubleshooting.
| Issue Type | Wired Headphones | Wireless Headphones |
|---|---|---|
| Connection Problems | Loose port, debris | Pairing, Bluetooth interference |
| Power Issues | Rare | Battery needs charging |
| Compatibility | Port type matters | Bluetooth version matters |
Quick Troubleshooting Steps
Try these steps if your headphones aren’t working:
- Disconnect and reconnect your headphones.
- Restart your iPhone.
- Check for iOS updates.
- Test headphones with another device.
- Try another pair of headphones with your iPhone.
If you get sound with another device, your iPhone may be the issue. If not, your headphones may need repair or replacement.
Hidden Causes Beginners Overlook
Many people don’t realize that audio routing settings can send sound to AirPlay speakers, not headphones. Always double-check output in Control Center.
Another common miss: some protective cases block the USB-C port slightly, causing a poor connection. Remove your case and try again.
