Google's Pixel Buds update saves sleep detection for people who also wear a Pixel Watch

Someone dozes off on a late train with Pixel Buds Pro 2 in and a podcast running. If they are wearing a Pixel Watch, its sleep sensing decides they are asleep, and the buds pause the episode, silence notifications and switch off touch gestures ^[3]. Both reports name the Pixel Watch as the trigger ^[2][3]. The Verge calls it the biggest feature in the update ^[2].

Google is pitching smarter earbuds. What actually ships is a feature list sorted by which other Google hardware the owner already has. Tap-to-mute mutes and unmutes the microphone with a tap during calls, but only with a Pixel phone ^[4]. Neither report says why a tap on the buds needs Google's own phone.

Of the five features in the coverage, two need a second Google device and Dynamic ANC needs the Pro 2 ^[12]. All five together take three Google products: Pro 2 buds, a Pixel phone and a Pixel Watch ^[11]. On the conditions the reports give, a Buds 2A owner with neither the phone nor the watch gets two of the five ^[12]. 9to5Google says one of those two, Gemini control, arrived with last month's companion app update ^[9].

So the Pixel Watch is required for one feature and the Pixel phone for one more ^[2][4]. Translation goes the other way, toward less hardware in hand. Google's wording, as quoted by 9to5Google, says owners can "leave your phone in your pocket and start translating instantly with a simple touch on your earbuds" ^[8].

The full update is for the household that already owns all three devices. For everyone else, I'd judge the buds on what works with the phone and watch they already have. The tradeoff is that a person without a Pixel Watch gives up the feature The Verge ranks first ^[2].

The sorting tool is a two-by-two. Put a Pixel phone on one axis and a Pixel Watch on the other. With neither, the buds get the Gemini commands and one-tap translation ^[5][7], plus Dynamic ANC on the Pro 2 ^[6]. Adding a Pixel phone brings tap-to-mute ^[4]. Adding a Pixel Watch brings sleep detection ^[2]. Only the corner with both, on Pro 2 buds, gets all five ^[11]. When a ticket says sleep detection does nothing, the first question is whether a Pixel Watch is on that wrist. The second is whether the buds show firmware release_6.144 under More settings > Firmware update in the Pixel Buds app ^[10].
