I installed iOS 11, set right AirPod to skip track and left for Siri. Downgraded to 10.3.3 and the double tap controls still work as it did in iOS 11. It doesn't show in the menu on the iPhone. The AirPods are reborn with the use of controls like these. Yes, I have AW but still wanted a way to skip tracks on the AirPods. It is so nice to double tap to skip, super fast and easy. Feels real natural, Siri does not. Edit: The "skip track" -control also works as Play, very convenient.
