Google is distributing new firmware to Pixel Buds Pro, Pro 2 and 2a. Tapping to mute the microphone during a call requires a connected Pixel phone, while pausing playback when the user falls asleep relies on sleep detection from a Pixel Watch. Touch-activated translation is also included. Dynamic noise cancellation that adapts to the ear’s fit is exclusive to Pro 2, so the same features are not being added to every model.
