Which should you buy?
The Liberty 5 edges ahead on the Mars Score (69.5 vs 76.1), but the 6.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Pixel Buds Pro 2 if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. The biggest gaps in its favor are driver size, spatial audio.
Pick the Liberty 5 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 — with case, battery — buds, water resistance, among others.
Both ship with comparable active noise cancellation, multipoint, so those specs don't separate the two — focus on the differences below.
Bottom line: the Liberty 5 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
