If you have a copy of the second generation Airpods Pro, we can mention that there is now a new version of the software available.
Apple is keeping quiet about exactly what is new this time, but the focus is likely to be on various bug fixes.
If you want to check if the update is installed, go to Settings -> General -> About -> Airpods and checks to see if it says the correct firmware version.
If it says something other than 5B58, place the headphones in the charging box and make sure they are connected to your iPhone, iPad or iPod Touch. Then the update should happen automatically.
In this context, it can be mentioned that Apple also sent out new software for Powerbeats Pro, Beats Fit Pro and Beats Studio Buds.
