Google - Pixel Buds A-Series vs Google - Pixel Buds Pro 2

The Pixel Buds Pro 2 edges ahead on the Mars Score (65.4 vs 69.5), but the 4.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Pixel Buds A-Series if you care most about driver size. The biggest gaps in its favor are driver size.

Pick the Pixel Buds Pro 2 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are battery — buds, battery — with case, active noise cancellation, among others.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
