Between the Beats Fit Pro and Liberty 4 Pro, the Beats Fit Pro comes out ahead in spatial audio, while the Liberty 4 Pro wins on battery — buds and battery — with case. Overall, the Beats Fit Pro scores 59.2 and the Liberty 4 Pro scores 72.8 on our Mars Score.
Which should you buy?
The Liberty 4 Pro is the clear pick on raw spec strength, leading by 13.6 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.
Pick the Beats Fit 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.
Pick the Liberty 4 Pro 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, weight per bud, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the Liberty 4 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
