JBL - Tour Pro 3 vs Anker - Liberty 4 Pro

The Tour Pro 3 edges ahead on the Mars Score (76.9 vs 72.8), but the 4.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Tour 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. The biggest gaps in its favor are battery — buds, battery — with case, driver size, among others.

Pick the Liberty 4 Pro if you care most about weight per bud. Its strongest claims are weight per bud.

Both ship with comparable active noise cancellation, 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.
