Which should you buy?
The Buds Pro 3 edges ahead on the Mars Score (74.5 vs 69.5), but the 5.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Buds Pro 3 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are battery — with case, battery — buds, water resistance.
Pick the Pixel Buds Pro 2 if you care most about weight per bud. Its strongest claims are weight per bud.
Both ship with comparable active noise cancellation, driver size, spatial audio, so those specs don't separate the two — focus on the differences below.
Bottom line: the Buds Pro 3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
