Google is rolling out a sizeable firmware update for its Pixel Buds line that brings a handful of genuinely useful features to owners of the original Pixel Buds Pro, the Pro 2, and the new Buds 2a. According to 9to5Google, the rollout follows last month's companion app update that added Gemini voice controls.
The headline feature, Dynamic Active Noise Cancellation, is reserved for the Pro 2. The rest of the bundle is shared across the older Pro (2022), the Pro 2 (2024), and the 2a (2025).
- Dynamic ANC on the Pro 2 adjusts audio based on how the earbuds sit in your ear
- Tap to Mute for calls works across all three models when paired to a Pixel
- Pixel Watch sleep sensing now auto-pauses media and silences notifications
- Enhanced Live Translate lets you start a conversation without pulling out your phone
- The original Pro (2022) is getting this update after Google initially left it unmentioned
- Firmware version software_release_6.144 lands via the Pixel Buds companion app
What is actually new
The cleanest win for the Pro 2 is Dynamic ANC. Rather than a fixed noise-cancelling level, the buds "automatically adjust audio or noise cancellation based on your ear seal," compensating for subtle shifts when the buds move. It is the kind of detail that only matters once you have worn earbuds on a long walk and noticed sound leaking in.
Tap to Mute is more obviously useful. During a call, you tap the bud to mute and tap again to unmute the microphone. The gesture requires a paired Pixel phone, which closes a few cross-platform edge cases.
Sleep-driven auto-pause is the sleeper feature, pun intended. With a Pixel Watch nearby doing sleep sensing, the buds pause media playback when you fall asleep, disable touch gestures, and silence notifications. People who fall asleep to podcasts will recognise the problem this solves.
Enhanced Live Translate trims the friction from earlier versions. You can now leave your phone in your pocket and start translating with a single tap on an earbud, drawing on the Google Translate app in the background.
Why this matters
Firmware updates for earbuds are usually security patches and codec tweaks. This one is closer to a feature drop, and it lands across three generations at once. That is notable because Google originally previewed these features in August without confirming that the original Pro (2022) would receive them. Quietly including it now is a small goodwill gesture to people who bought into the line five years ago.
There are two practical limits to keep in mind. First, the most interesting feature, Dynamic ANC, is exclusive to the Pro 2. Owners of the older Pro or the cheaper 2a get the headline features but not the headline hardware trick. Second, several features lean on a paired Pixel phone and a Pixel Watch, which narrows the real-world benefit for iPhone or non-Pixel Android users.
A practical scenario
Say you are a product manager running standups across time zones. You wear your Pixel Buds Pro 2 all day. With the new firmware, you can mute yourself on a noisy train with a single tap rather than fishing for the on-screen button, and when a meeting overruns into lunch you can pop out the buds, hand the phone to a colleague and ask them to translate, all without unlocking the screen.
At night, the buds pair with your Pixel Watch and pause your podcast the moment you drift off, instead of playing a full episode into your pillow.
What to watch next
Check the Pixel Buds companion app under More settings, then Firmware update, to trigger the pull of software_release_6.144. If you own the original Pro, watch closely: Google did not initially list it as eligible, so the rollout may stagger.
Key takeaways
- Update via the Pixel Buds companion app under More settings, then Firmware update
- Pair with a Pixel phone to unlock Tap to Mute and the new gesture controls
- Set up Pixel Watch sleep sensing to use the new auto-pause feature
- Only the Pro 2 gets ear-seal-based Dynamic ANC
