AirPods are a staple for most iOS users, whether you’re still rocking the original design using the AirPods 2nd Gen or the upgraded noise-canceling AirPods Pro 2, they consistently have a reputation for being excellent wireless earbuds. Once you pair your pods with your listening device, they are designed to stay connected, automatically pairing when Bluetooth is turned on and their case is open. However, if your Bluetooth connection is spotty, you’re having trouble connecting, or you want to change the automatic-pairing device, it can be helpful to select “forget device” in Bluetooth settings and start fresh. Reconnecting is simple and straightforward, and if you set up your AirPods originally, rest assured that it follows the same steps. Here we’ll walk you through what you need to do to successfully reconnect your AirPods after you instruct them to “forget device.”
