Pick the Galaxy Buds 3 Pro if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. The biggest gaps in its favor are spatial audio, water resistance.
Pick the Ear (a) 2 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, driver size, among others.
Both ship with comparable active noise cancellation, multipoint, so those specs don't separate the two — focus on the differences below.
