A:Answer Hi Delirious! Great question.
The QC35 Series II offers the same unmatched noise reduction technology, audio performance, and 20-hour battery. However, it has a new Action button located on the left ear cup. In countries and languages where the Google Assistant is available, that button gives you instant access to the Google Assistant. In countries where the Google Assistant is not available, it lets you quickly toggle through three different ANR settings for optimal performance wherever you go.
Hope that helps!
Best Regards.
