Mark Gurman at Bloomberg:

The model coming as early as this year will let people summon Apple’s Siri digital assistant without physically tapping the headphones by saying “Hey Siri.” The function will work similarly to how a user activates Siri on an iPhone or a HomePod speaker hands-free.

I would live this addition. I currently have the double-tap feature on my AirPods set to play/pause because that is way more useful at out open office at work. Having Hey Siri would give me the best of both worlds.

I was considering buying the new charging case for my current set when the AirPower mat is finally released, but now I think I will just wait for the new version of AirPods.
