Which should you buy?
The Boombox 3 is the clear pick on raw spec strength, leading by 13.3 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 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 Boombox 3 if you care most about output power and battery. Its strongest claims are output power, battery, low-end response.
Both ship with comparable water resistance, stereo pairing, so those specs don't separate the two — focus on the differences below.
Bottom line: the Boombox 3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
