Pixel Buds Pro 2: What’s Included in the Latest Rollout

Announcement

Hey Pixel Buds Community,

We’re rolling out new features on the latest firmware update (version 4.467) for your Pixel Buds Pro 2 to enhance your audio and Gemini experience.

What’s included:

• Adaptive Audio

Adaptive Audio keeps you aware of your surroundings while dynamically reducing the volume of unwanted noises and sounds. Whether you’re out walking, cycling, on the metro, or at the gym, you can stay alert while still enjoying your music, podcasts, and audiobooks.(1)

• Loud Noise Protection

When a loud noise occurs suddenly, your earbuds help reduce its volume to protect your hearing. This means a nearby fire truck’s loud siren won’t blare in your ears at maximum volume.(1,2)

• Head gestures for calls and texts(3) 

Manage calls and text messages without lifting a finger. Head gestures allow you to control your Pixel Buds with simple head movements. Nod to answer a call or reply to a text, or shake your head to decline; making it a truly hands-free experience.(4)

• Clear Gemini Live interactions in noisy environments

Communicate with your Gemini Live clearly, even in a noisy environment. Advanced audio processing prioritizes your voice and eliminates background noise so your conversations with Gemini Live are uninterrupted, even when others are talking around you.(4,5)

Get the Update

The Pixel Buds Pro 2 update will be rolled out gradually to all users. To ensure you receive the update, please keep your Pixel Buds Pro 2 charged and connected to your phone, and update to the latest Google app. 

Here are the details on how to receive the firmware update for your Pixel Buds Pro 2.

• Automatic Updates

The firmware update will be downloaded automatically when your Pixel Buds Pro 2 is connected to a Pixel or Android 6.0+ device. This takes about 10 minutes, and you can continue using your earbuds during this time. The update will begin installing the next time you place your earbuds into the charging case with a sufficient charge. This process also takes about 10 minutes.

• Manual Updates

If you have automatic updates turned off, you can manually trigger the update from the Pixel Buds app on your phone. Here’s how:

1. Place your earbuds securely into their charging case.
2. Open the Google Pixel Buds app .
3. Go to More settings  Firmware update.
4. Tap Manual update available and follow the on-screen instructions. This process may take about 15 minutes to complete.

You can also download the latest firmware update from the web companion app at mypixelbuds.google.com.
