Release year	2024	2024
Chip	Google Tensor A1 in each earbud Google says Tensor A1 adapts audio to the environment up to 3 million times per second and runs noise cancellation twice as strong as the original Pixel Buds Pro; music and noise-cancellation processing run on separate paths. Google	—
Noise control	Active Noise Cancellation with Silent Seal 2.0; Transparency mode; active in-ear pressure relief; Conversation Detection Pressure relief reduces the plugged-ear feeling of sealed earbuds. Conversation Detection pauses music and switches to transparency when you start talking. Google	—
