JBL - Xtreme 4 vs Sonos - Move 2

The Xtreme 4 edges ahead on the Mars Score (73.9 vs 69), but the 4.9-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Xtreme 4 if you care most about output power and water resistance. The biggest gaps in its favor are output power, water resistance.

Pick the Move 2 if you care most about low-end response. Its strongest claims are low-end response.

Both ship with comparable battery, stereo pairing, 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.
