Which should you buy?
The Boom 2 Plus edges ahead on the Mars Score (73.1 vs 76.4), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The SoundLink Max 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 Boom 2 Plus if you care most about output power. Its strongest claims are output power.
Both ship with comparable battery, water resistance, low-end response, 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.
