Which should you buy?
The MW09 edges ahead on the Mars Score (79.3 vs 74.5), but the 4.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the MW09 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 — buds, battery — with case, water resistance.
Pick the Buds Pro 3 if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. Its strongest claims are weight per bud, spatial audio.
Both ship with comparable active noise cancellation, driver size, multipoint, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
