An update for Pixel Buds Pro 2 and Pixel Buds 2a adds a clever interaction with Pixel Watch sleep detection: when the watch detects sleep, compatible earbuds can pause audio, silence notifications and turn off touch controls. The Pro 2 also gains Dynamic ANC that adapts to fit, while Pixel-phone users gain a tap-to-mute gesture during calls.
This is an interesting example of two wearables cooperating to solve a real problem rather than simply collecting more metrics. It is not a reason to replace AirPods in an Apple-centric setup, but it is a useful benchmark for how well connected-device ecosystems can behave.
Do this: compare the feature set with what your current watch and earbuds do before buying anything; the capability depends on specific Pixel hardware.
