AirPods will often times say they're “connected” but still play sound from your phone. If this happens to you, there are several proven ways to fix it: Try resetting the Bluetooth on your phone by toggling it off then on again. Reset your AirPods by using “Forget This Device”.
Put AirPods Back in the Case Since both the AirPods have to connect to your phone separately, one of them likely bumped into a problem during the pairing process. Turning them off and back on will force them to reconnect, which should resolve the issue. Place both AirPods into the case and close the lid.
Set a Volume Limit Typically, Volume Limit is set to “Off,” but it doesn't hurt to check if that's true. It could be the reason why your AirPods play so quietly you don't hear them. Go into Settings > Music > Volume Limit > set the slider to Maximum (turning volume limit off).
Turn Bluetooth OFF & ON Again Sometimes your AirPods fail to connect to your phone properly, so one or both sides don't receive sound. Turning Bluetooth off and back on forces your phone to reestablish the connection all over again. This time, hopefully, without issues.
Performing a Reset You might also try doing a full reset by: Place the Airpods back in their case and close. Open the Airpod case and press the small button at the back of the case for a few seconds. The light should blink amber three times.
If you can't connect to your iPhone, iPad or iPod touch Make sure you have an iPhone or iPod touch with the latest version of iOS, or an iPad with the latest version of iPadOS. Put both AirPods in the charging case and make sure both AirPods are charging. To make sure Bluetooth is on, go to Settings > Bluetooth.
After pairing each AirPod individually, return them both to the case and try pairing a final time by holding the Setup button again. If this doesn't work, go into the Bluetooth settings on your iPhone to forget both AirPods, then try pairing them together again.
Just go to your Settings -> Bluetooth and make sure the green indicator is on and also make sure your AirPods are properly paired to your iDevice. If your Bluetooth connection is acting weird or you have many devices, try turning it off on purpose and turn it on 20 seconds later.
If your left AirPod is not working, you need to reset your AirPods. Go to Settings > Bluetooth > Info icon next to your AirPod name > Forget This Device. Then, with both AirPods in the case and the lid open, hold the button on the back until the status light blinks white.
Close the lid, then hold the setup button on the charging case until it flashes white. Go to the Home Screen on your iPhone or iPad. Open the charging case (with your AirPods inside) near your device and wait for the setup animation to appear. Tap 'Connect,' then 'Done.
Wrong settings If your device isn't configured with the correct settings, your AirPods may not maintain a consistent connection. To ensure your AirPods stay connected to each device you pair them with, it's good practice to review the Bluetooth settings to ensure there are no anomalies.
Make sure Bluetooth is enabled, and look for available devices. The AirPods should show as an option as long as the AirPods case is still flashing white. Tap “pair” and allow the phone and the AirPods to establish a connection to your phone.
Performing a Reset Open the Airpod case and press the small button at the back of the case for a few seconds. The light should blink amber three times. Close the Airpods case again.
First, make sure your AirPods are not physically damaged and fully charged. You can simply test the hardware with a mobile phone or another Windows computer. Remove AirPods and pair them again. Restart your computer to resolve the temporary glitch of the system.
