Hi M-Dannet,
We'd like to share some suggestions to help get you on the best path. With issues like you mention, its best to start with the guidance in If your AirPods won't connect - Apple Support
- "Make sure that your iPhone or iPod touch has the latest version of iOS or that your iPad has the latest version of iPadOS.
- Put both AirPods in the charging case and make sure that both AirPods are charging.
- To make sure that Bluetooth is on, go to Settings > Bluetooth.
- If your AirPods are connected, make sure that they're selected as your audio device. If your AirPods appear in the list of devices but they don't connect, go to the next step.
- Close the lid, wait 15 seconds, then open the lid. Press and hold the setup button on the back of the charging case for up to 10 seconds. The status light on the front of the charging case should flash white, which means that your AirPods are ready to connect.
6.Hold the charging case, with your AirPods inside and the lid open, next to your iPhone, iPad, or iPod touch.
7.Follow the steps on the screen of your iPhone, iPad, or iPod touch.
8.Test your AirPods. If you still can't connect, reset your AirPods."
In addition to what you mentioned same issue with new replacement, we would also recommend seeing if you have an issue with another device as this can help isolate if AirPods or iPhone related. If you go through all those steps and test with another device, we would recommend contacting Apple Support to share the results.
Thanks for using Apple Support Communities.
