A couple of months after the last update, the American company has released a new version of the firmware for the AirPods Max. At the moment it is not known what it has added or what it has removed. Or if he has not done either one or the other. What is clear is that with the addition of Spatial Audio, which we already know works, it is likely that it will just be a matter of obtaining only a software improvement. Either way we already have version 3E756 with us.
Apple has released firmware version 3E756 for AirPods Max. Previously, the firmware version was 3C39. So, if anything, the firmware version has gotten a bit longer. As for what's new, however, as mentioned above, that remains to be seen. Apple does not typically issue release notes for these types of updates. So remains a mystery this time.
It is more than possible that Apple is addressing some underlying problems that many users have had and that have become very popular. It is also possible that Apple aims to fix other problems or improve others. Even if it is only slight improvements and security improvements. The usual and normal in basic updates.
Updates to AirPods are usually done automatically, but it is true that it can be forced a bit. You just have to connect the AirPods Max to an iPhone or an iPad and go to Settings -> General -> About -> AirPods. There you will see which is the version of your headphones and perhaps that way you are requesting that the new version be downloaded now. But it will be something that is done without realizing it.
We are pending in case there is any news worth telling.
