Which should you buy?
These two are nearly even on the Mars Score (74.5 vs 76.1). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the Buds Pro 3 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 — buds, battery — with case, weight per bud.
Both ship with comparable active noise cancellation, water resistance, multipoint, so those specs do not separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
