Best portable Bluetooth speakers with loud sound and strong bass

Top pick: JBL Xtreme 5. It's the one built for exactly this — big, room-filling volume with the deepest bass of the group, and it still runs on battery and takes knocks. Best for parties, patios and anyone who wants the loudest sound per dollar.

• JBL Charge 6 — the everyday all-rounder: punchy bass, rugged, easy to carry; the sensible choice if the Xtreme is more speaker than you need.
• Bose SoundLink Max — the most refined sound and best build here; go for it if you want clean, balanced bass over sheer volume.
• Ultimate Ears Everboom — tough, outdoor-first pick with good bass and a wide soundstage.
• Soundcore Boom 2 — the budget bass champion; loud and thumpy for casual use.
• Bose SoundLink Plus — slim and rugged, but reviewers note bass is limited, so skip it if bass is the priority.
• Sonos Roam 2 — small and smart-home friendly; fine for a room, not for a crowd.
