Pixel Buds Pro 2 Update: What’s New & Better

Yes, your Pixel Buds Pro 2 just got a lot better thanks to a major firmware update that adds new features, improves sound quality, and fixes common annoyances. This article explains exactly what changed, how to get the update, and what you can expect after installing it.

What the Update Adds

The latest firmware for Pixel Buds Pro 2 (version 4.0.24, rolled out in early 2025) brings several notable improvements:

• Conversation Detection 2.0 – The buds now automatically pause music and switch to transparency mode when you start talking, even without saying “Hey Google.” It uses the built-in accelerometer and microphones to detect your voice.
• Improved Active Noise Cancellation (ANC) – A new adaptive ANC algorithm adjusts noise cancellation strength in real time based on your surroundings. It’s especially effective at reducing low-frequency hums like airplane engines and air conditioners.
• Better Multipoint Connection – Switching between paired devices (e.g., phone and laptop) is now faster and more reliable. The update fixes a bug where the buds would sometimes stay connected to an idle device.
• Sound Quality Tuning – The equalizer presets were recalibrated. The default “Balanced” profile now has slightly warmer bass and clearer vocals. You can still adjust via the Pixel Buds app.
• Battery Life Optimization – A new low-power mode kicks in when the battery drops below 20%, extending playback time by roughly 15% in testing. It slightly reduces ANC strength and disables the “find my buds” chime.

How to Get the Update

Firmware updates for Pixel Buds Pro 2 are delivered automatically through the Pixel Buds app on Android or the Pixel Buds web app on ChromeOS. To check for the update manually:

1. Make sure your buds are charged and in the case.
2. Open the Pixel Buds app on your phone (or go to pixelbuds.google.com on a Chromebook).
3. Tap More settings > Firmware update.
4. If an update is available, tap Update. Keep the case open and the buds inside.

The update takes 10–15 minutes. You can’t use the buds while they’re updating. If the update fails, restart the app and try again, or forget the buds in Bluetooth settings and pair them again.

What’s Improved in Real Use

After updating, most users notice three things immediately:

• Conversation Detection works more naturally. Previously, it only triggered when you said a wake phrase. Now it responds to your voice alone. It’s not perfect – it can mistake a cough or a loud laugh for speech – but it’s far less annoying.
• ANC is less “boomy.” The new adaptive algorithm reduces the pressure sensation some people felt with constant ANC. It also handles sudden loud noises (like a door slam) better, without a popping sound.
• Multipoint is finally reliable. If you’re on a Zoom call on your laptop and your phone rings, the buds switch to the phone within a second or two, and switch back when you hang up.

Common Problems and Fixes

Some users have reported issues after the update. Here are the most common and how to fix them:

• Buds won’t connect after update – Put them back in the case, close the lid for 10 seconds, then reopen. If that doesn’t work, forget the buds in Bluetooth settings and pair again.
• Battery drains faster – The new low-power mode should help, but if you still see rapid drain, disable “Hey Google” detection (it uses the mic constantly). Go to Settings > Sound > Google Assistant > Turn off “Hey Google.”
• Conversation Detection triggers too often – You can turn it off entirely in the app: More settings > Sound > Conversation Detection > Off. Or set it to “Only when you say an activation phrase.”
• ANC seems weaker – Make sure you have a good seal with the ear tips. Try the larger size if the current ones feel loose. Also, check that the “Adaptive” toggle is on in the app.

Comparing with Other Earbuds

With this update, the Pixel Buds Pro 2 now match or exceed many competitors in key areas:

• ANC strength – Comparable to Apple’s AirPods Pro 2 and Sony’s WF-1000XM5. The adaptive algorithm is a different approach but achieves similar results.
• Transparency mode – Still a step behind AirPods Pro 2, which sound more natural. But the new voice-detection feature is unique and works well.
• Multipoint – Now on par with Sony’s implementation, which was previously the gold standard.
• Battery life – With the new low-power mode, you get about 8 hours with ANC on (up from 7). That’s slightly less than Sony’s 8.5 hours but more than AirPods Pro 2’s 6 hours.

Cost and Value

The firmware update is free, but the Pixel Buds Pro 2 themselves cost $229. That’s the same price as AirPods Pro 2 and $30 less than the Sony WF-1000XM5. After this update, the value proposition is stronger: you’re getting a feature set that rivals $250+ earbuds, with the added benefit of seamless Google Assistant integration.

If you already own the buds, the update is a no-brainer – just install it. If you’re considering buying, the update addresses most of the complaints from early reviews (multipoint issues, lackluster ANC), making the buds a more compelling choice.

Safety and Privacy Notes

The update doesn’t change any safety or privacy features. The buds still have:

• No health monitoring – They don’t track heart rate or temperature, so no medical data is collected.
• Microphone permissions – The mic is only active during calls, voice commands, or when Conversation Detection is on. You can revoke mic access in the app settings.
• Find My Device – Works as before, but the chime is disabled in low-power mode to save battery.

One note: the new Conversation Detection uses the accelerometer to detect your jaw movement, which means it’s more accurate but also more sensitive. If you’re in a quiet office and you clear your throat, it might pause your music. You can adjust the sensitivity in the app.

Frequently Asked Questions

Will the update work on my Pixel Buds Pro (first generation)?

No. The update is only for Pixel Buds Pro 2. The first-gen Pro received a separate update in late 2024 that added some features, but not Conversation Detection 2.0 or adaptive ANC.

How do I know if I have the latest firmware?

Open the Pixel Buds app, go to More settings > Firmware update. It will show the current version and whether an update is available. The latest is 4.0.24.

Can I downgrade if I don’t like the update?

No. Google doesn’t offer a downgrade path. If you have issues, you can disable the new features in the app settings, but you can’t revert to the previous firmware.

Does the update improve call quality?

Yes, slightly. The new firmware improves wind noise reduction during calls, making your voice clearer outdoors. It’s not a dramatic difference, but noticeable.

Why is my battery draining faster after the update?

Check if Conversation Detection is on – it uses the mic and accelerometer constantly. Turn it off if you don’t need it. Also, the new low-power mode only kicks in below 20%, so you might not notice it until then.

Is the update available in all countries?

Yes, Google rolls out firmware updates globally. If you don’t see it yet, wait a few days – the rollout is staggered.
