Pick the Galaxy Buds 3 if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. The biggest gaps in its favor are weight per bud, spatial audio.
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. Its strongest claims are battery — buds, battery — with case.
