Google Assistant on headphone officially debuted on Bose QC35 II, last week. While many publications already uploaded reviews of the headphones with Assistant, but there was not much information available from Google.

The company finally realised the need for educational videos to show the working of Assistant on headphones. Google has posted three videos to enlighten the inquisitive minds about how exactly Assistant takes over the functioning of headphones. The Bose QC35 II is the first device in the lineup, more models are expected to launch, and one model could be from Google itself.
