Buying guide

Water resistance beats everything outdoors

All four are at least IP67, which means dust-tight and safe in a meter of water for 30 minutes. If you'll use it by salt water, the Boom 3i is the only one explicitly salt-water rated.

Battery claims assume moderate volume

Manufacturers rate battery at 50% volume or lower. Crank it to party level and expect noticeably less — the JBL's 24 hours can drop fast at high output. Read 'up to' as a ceiling, not a promise.

Stereo vs. mono

The JBL and Bose play true stereo from one box; the Sonos and Soundcore are mono. Stereo matters more for music at a distance — a mono speaker sounds fine up close but collapses into a point source across the room.

Smart features are the Sonos's edge

Only the Roam 2 connects to Wi-Fi, which means AirPlay, a multi-room system, and voice assistants when you're home. If you never plan to use those, you're paying for features you won't touch.

Questions

Frequently asked questions

Which portable speaker is loudest?

On paper the Soundcore Boom 3i's 50 W is the highest rating, but loudness also depends on driver efficiency. The JBL Charge 6 and Bose SoundLink Max are the picks if you want big, clean sound outdoors.

Can these pair together for stereo?

The JBL and Bose support multi-speaker pairing and stereo mode. The Sonos Roam 2 pairs with other Sonos speakers over Wi-Fi. The Boom 3i supports stereo pairing but not a long chain.

Are they safe in a pool or ocean?

All four are IP67/IP68, so they survive splashes, rain, and brief submersion. The Sonos Roam 2 and Soundcore Boom 3i actually float. Rinse with fresh water after salt water.

Which is best for travel?

The Sonos Roam 2 (430 g) and Soundcore Boom 3i (780 g) are the most portable. The Bose SoundLink Max at 2.1 kg is a shoulder-strap speaker, not a backpack speaker.

Do I need Wi-Fi on a portable speaker?

Only if you want AirPlay, multi-room audio, or voice assistants at home. If you'll use it purely over Bluetooth, the Sonos's Wi-Fi is unnecessary — and the other three are simpler.
