If your used AirPods 4 with Active Noise Cancellation (ANC) are not functioning as expected, there are several troubleshooting steps you can follow to resolve common issues.

Initial Checks

Before diving into complex solutions, ensure that your AirPods are properly charged and connected. Low battery levels can affect performance, especially features like ANC.

Verify that your device’s Bluetooth is enabled and that your AirPods are correctly paired. Sometimes, simply reconnecting can fix minor glitches.

Troubleshooting Steps

1. Restart Your Devices

Turn off your device and AirPods, then turn them back on. Reconnect your AirPods and check if the issue persists.

2. Reset Your AirPods

If problems continue, reset your AirPods to factory settings. To do this:

  • Put your AirPods in the charging case and close the lid.
  • Wait 30 seconds, then open the lid.
  • Press and hold the setup button on the back of the case until the status light flashes amber, then white.
  • Reconnect your AirPods to your device.

Check for Firmware Updates

Ensure your AirPods have the latest firmware. Connect them to your device, and update your device’s software if necessary. Firmware updates can fix bugs and improve performance.

Adjust Settings

Verify that ANC is enabled in your device’s Bluetooth settings. On iOS devices, go to Settings > Bluetooth, tap the info icon next to your AirPods, and ensure Noise Cancellation is turned on.

Additional Troubleshooting

Clean Your AirPods

Dirty microphones or speakers can impact ANC and sound quality. Carefully clean your AirPods using a soft, dry cloth and a small brush.

Test with Different Devices

Connect your AirPods to another device to determine if the issue is with the AirPods or your original device.

When to Seek Professional Help

If none of the above steps resolve the issue, contact Apple Support or visit an authorized service provider. Your AirPods may require professional repair or replacement.
