These headsets might not have dedicated Google Assistant buttons like the Bose QC35 II Bluetooth headphones, but they also won't cost you $350 to upgrade if you already own a set. However, you can change the noise cancellation button to summon Google Assistant instead.

This new integration also gives you direct access to Google Assistant on iOS -- these headphones were previously compatible with Siri and defaulted to Apple's voice assistant before this. You can also now receive Google Assistant spoken notifications on these two Sony headsets, and push-to-talk works faster.

At CES, Google promised that headsets new and old would work with Google Assistant, and it looks like the company is living up to its promise. Three more Sony headsets should be getting a similar update soon: the WH-CH900N, the WH-H900N and the WF-1000X.
