Between the LinkBuds Fit and Buds Pro 3, the LinkBuds Fit comes out ahead in several specs, while the Buds Pro 3 wins on battery — with case and battery — buds. Overall, the LinkBuds Fit scores 53.8 and the Buds Pro 3 scores 74.5 on our Mars Score.
Which should you buy?
The Buds Pro 3 is the clear pick on raw spec strength, leading by 20.7 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The LinkBuds Fit doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the Buds Pro 3 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, driver size, among others.
Both ship with comparable active noise cancellation, spatial audio, multipoint, so those specs don't separate the two — focus on the differences below.
Bottom line: the Buds Pro 3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
