Apple has released firmware update 2D27 for AirPods Pro users around the globe. As usual, you can’t force the update yourself.

A month ago Apple released a brand new firmware for AirPods Pro users called 2D15. Today, Apple is taking things up a notch with the release of version 2D27. There’s no changelog for this update so there is no way of telling what this new update brings to the table apart from unknown bug fixes. Also, you can’t force the update onto your AirPods. Just connect to an iOS device, an iPhone, iPad or iPod touch, and the update will automatically install on their own.
