JBL - Boombox 3 vs Sonos - Era 100 Portable (rumored)

The Boombox 3 is the clear pick on raw spec strength, leading by 42.4 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 Boombox 3 if you care most about battery and low-end response. The biggest gaps in its favor are battery, low-end response, water resistance, among others.

The Era 100 Portable (rumored) similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
