The short answer

Bose SoundLink Max comes out ahead by a clear margin (4.3 vs 3.9). The gap is mostly about outdoor users wanting premium sound — read the strengths below before deciding.

Bose SoundLink Max
Higher ratedRanked #2 in Best Waterproof Bluetooth Speakers
Bose SoundLink Max
7 sources$309.99as of Aug 1

The Bose SoundLink Max pairs excellent sound quality with an enjoyable user experience in a premium, outdoor-friendly package. What Hi-Fi? praised the rugged design, the powerful bass, and the lively audio, while noting it lacks transparency and has no built-in microphone. At $399 it sits in premium territory next to competitors like the Dali Katch G2 and Sonos Move 2. Buyers who want a durable, high-performing portable speaker for outdoor use will be satisfied; anyone who needs call functionality won't.

Strengths
  • — Rugged, ergonomic design with silicone wrapping and carry handle
  • — Powerful, tight bass response
  • — Lively, energetic sound quality
Watch-outs
  • — Not the most transparent-sounding
  • — No built-in mic for taking calls

Soundcore Boom 3i
Ranked #5 in Best Waterproof Bluetooth Speakers
Soundcore Boom 3i
2 sources$129.99as of Aug 1

The Soundcore Boom 3i is a rugged, bass-forward portable speaker with an IPX7 rating and a carry strap, aimed at pool decks and campsites rather than critical listening. SoundGuys scored it 8.4 out of 10 and called it the best waterproof Bluetooth speaker they had tested; PCMag was markedly cooler at 3.5 out of 5. The split is the story — the durability and the low end are genuinely good, the app and the finer detail in the mids are not. Casual outdoor listeners will be happy; anyone chasing tonal accuracy should not be.

Strengths
  • — Compact and portable design suitable for outdoor use
  • — Solid bass response and overall sound quality for its size
  • — Built-in rechargeable battery with decent runtime
Watch-outs
  • — Companion app support is limited next to rival speakers at the price
  • — No active noise cancellation and little in the way of audio tuning
  • — Mid and high frequencies lack detail, which shows on acoustic and vocal material

How they stack up

Bose SoundLink Max

The Bose SoundLink Max delivers powerful, lively sound and a rugged design, but lacks the app features and water resistance of the JBL Charge 6 and JBL Boombox 4. While the Soundcore Boom 3 and Bose SoundLink Flex offer more affordable options, the Max's premium price is justified by its superior bass response and button feedback. It's not as versatile as the JBL Authentics 500 for home use but excels in outdoor performance without call capability.

Soundcore Boom 3i

The Soundcore Boom 3 offers a compact design and solid bass for its size, but lacks the advanced app features and water resistance of the JBL Charge 6 and JBL Boombox 4. Compared to the Bose SoundLink Flex, it has less refined EQ options and minimal hardware upgrades, though it's more affordable. Unlike the Bose SoundLink Max, it doesn't offer premium sound quality or call functionality, making it a basic choice for casual users.
