We understand that your AirPods Pro will randomly connect to your iPhone and then disconnect. Unpairing and repairing the AirPods is a good first step to try.
If your AirPods won't stay connected, outdated device firmware might be the reason behind the issue. With your AirPods connected to your iPhone, head over to Settings > General > About > AirPods and check whether Firmware Version is up to date.
You may have configured the iPhone accessibility settings to play the earbuds at different levels. Go to the iPhone Settings > Accessibility > Audio/Visual. Make sure the slider is balanced, with the button in the middle between the L and the R. Re-pair the AirPods with the iPhone.
One of the settings you need to check is the Volume Limit. If this feature is set to minimal or low, your audio is adjusted automatically to that volume. To change it, go to your Device's Settings, then tap on the Music option and then make sure that your Volume Limit is set to maximum.
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”.
This is fine when there aren't many Wi-Fi sources, but more Wi-Fi sources means less space in the spectrum for Bluetooth to talk to your device. This causes your AirPods to cut out. Bluetooth range also plays an important factor. This is defined by how far away you can move from your device to remain connected.
Reset your AirPods Go to Settings > Bluetooth and tap the "i" icon next to your AirPods. 2 Then tap Forget This Device, and tap again to confirm. With the lid open, press and hold the setup button on the back of the case for about 15 seconds, until you see the status light flashing amber.
Usually, the problem is that your AirPods are connected via Bluetooth yet the output source is different. Go to System preferences -> Sound and then to the “Output” tab. Select your AirPods and if they are already selected try switching back to the computer audio and then select the AirPods again after 10 seconds.
Make sure the AirPods have some charge and open the lid. Press and hold the setup button on the back of the case until the led flashes from amber to white color to put reset them. Now that you've done a hard reset, it's time to pair them again. Open the lid near your iPhone or iPad and follow the instructions.
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.
