TL;DR
Put AirPods in the case, close the lid for 30 seconds, open it, and hold the setup button on the back until the light flashes white. Then on your iPhone, go to Settings > Bluetooth > forget the AirPods and re-pair them. That solves 80% of connection issues.
Why AirPods Fail to Connect
AirPods use Apple's W1 or H1 chip for Bluetooth pairing, which is normally seamless. Connection problems usually come from: the AirPods being paired to another device in your iCloud account, a corrupted pairing state, a firmware glitch, Bluetooth interference, or low battery. Here's how to work through each cause.
Fix 1: Check Which Device They're Connected To
If you have multiple Apple devices signed into the same iCloud account (iPhone, iPad, Mac), your AirPods auto-switch between them. They may currently be connected to your Mac rather than your iPhone. On your Mac: System Settings > Bluetooth > find AirPods > disconnect. On iPad: Settings > Bluetooth > find AirPods > disconnect. This frees them up to connect to your iPhone.
Fix 2: Toggle Bluetooth Off and On
Settings > Bluetooth > toggle off, wait 5 seconds, toggle back on. Alternatively, use Control Center. With the AirPods case open near your iPhone, the pairing popup should appear within a few seconds.
Fix 3: Forget AirPods in Bluetooth Settings and Re-pair
Settings > Bluetooth > tap (i) next to your AirPods > Forget This Device > confirm. Then open the AirPods case near your iPhone and follow the pairing prompt. This clears the corrupted pairing state and establishes a fresh connection.
Fix 4: Check AirPods Battery
AirPods won't connect if they're fully dead. Put them in the case for at least 15 minutes before trying again. Check battery: open the case next to your iPhone to see the battery widget, or ask Siri. If the case itself is out of battery (no light when you open it), charge the case first — AirPods can't charge inside a dead case.
Fix 5: Reset Your AirPods
This is the most reliable fix for persistent connection issues. Place both AirPods in the case and close the lid. Wait 30 seconds. Open the lid. Hold the setup button on the back of the case for 15 seconds — until the status light flashes amber, then white. The AirPods are now reset. Open the case near your iPhone and pair as new.
Fix 6: Restart Your iPhone
Restart your iPhone and try again. This clears Bluetooth subsystem state that can prevent devices from connecting even when everything appears configured correctly.
Fix 7: Check for Interference
Bluetooth operates at 2.4GHz, which is shared with WiFi (2.4GHz band), microwaves, and other wireless devices. In high-interference environments (busy offices, apartments with many WiFi networks), you may experience connection drops. Try moving to a different room or disabling your phone's WiFi temporarily to test.
If your AirPods connect but sound cuts out or one side stops working after connecting, see our [AirPods one side not working](/guides/airpods-one-side-not-working) guide. For any suspected hardware defects, check our [Apple recalls guide](/guides/apple-recall) to see if your AirPods model has any active service programs.
