The Pixel Buds Pro 2 and Pixel Buds 2a, which debuted today alongside the Pixel 11 series, are receiving a set of hands-free features to make the earbuds much more adaptable for daily use starting this fall. That sounds like a useful extension of the Pro 2's existing ANC system, which Google says already cancels up to twice as much noise as the original Pixel Buds Pro. The Pro 2 is 27% smaller and 24% lighter than the original Pixel Buds Pro, and it comes with Google’s Tensor A1 chip and a redesigned fit.
