It appears Sony has begun the process of pushing true Google Assistant integration to select models of headphones and earbuds, specifically the WI-1000X and WH-1000XM2.
First spotted by Android Police, this update will allow for users to hear notification read backs via Assistant, plus it will let you speak to Assistant more easily for requesting info and issuing commands.
If you own one of these first headsets to receive the update, simply update your firmware via the Headphones Connect app on Google Play.
If you don’t see your Sony headset listed about, don’t worry, Sony mentioned earlier this year that it intends to roll out Assistant integration to the WF-1000X, WH-CH900N, and h.ear on 2 WH-H900N in the future.
