How to connect airpod pro to non-Apple devices using bluetooth

Place the Airpods in their case. Close the case. Open the case. Hold the hidden circular button on the back of the case for 15+ seconds or until the Airpods case light starts to blink white. This will put the Airpods Pro into pairing mode. Now all Bluetooth devices should be able to see the Airpods Pro and connect to them.
