Google rolls out major Pixel Buds update with sleep detection and dynamic ANC

Key points

• Firmware 6.144 adds sleep detection to Pixel Buds 2A and Pro 2, pausing media and silencing notifications when paired with a Pixel Watch.
• Dynamic Active Noise Cancellation is exclusive to the Pro 2, adjusting audio levels based on ear seal quality.
• New Gemini voice commands allow users to control ANC, EQ, and touch settings on both models.
• Tap-to-mute functionality is available for calls, but requires a paired Pixel phone.
• The original Pixel Buds Pro will not receive this update, despite initial announcements suggesting otherwise.

Background

In August 2026, Google teased upcoming software enhancements for its earbuds. The Pixel Watch has been under scrutiny for its sleep tracking accuracy, as noted in earlier coverage of its sleep score system. This update integrates the earbuds more deeply with the watch's sleep sensing capabilities.

How outlets are covering it

The Verge and Thurrott.com emphasize the new features, particularly sleep detection and dynamic ANC. Android Central highlights the concurrent $60 price drop for the Pro 2, bringing it to $170. All sources confirm the update is rolling out now, but The Verge notes that Google initially claimed the original Pixel Buds Pro would receive the update before retracting that statement.

Why it matters

This update enhances the Pixel Buds' integration with Google's ecosystem, particularly the Pixel Watch and Gemini AI. The price cut makes the Pro 2 more competitive in the premium earbuds market.
