Short answer: the JBL Xtreme 5 for sound quality, the Bose SoundLink Max for the lower price. These rank #17 and #2 out of 120 large speakers, $0.95 apart, and the gap in measured performance is large.
The Xtreme 5’s pros describe it as a fantastic-sounding speaker with excellent off-axis dispersion, reaching bass well below 40Hz and beating both the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. It also plays clean at volume, a contrast the pros draw explicitly against the JBL Boombox 4. The Bose’s own cons tell a different story: a big peak in the upper bass, a dipped midrange, and further peaks and dips above it, plus distortion above 80% volume.
The Xtreme 5 isn’t without flaws. Its cons note a hole in the mid-upper bass that can’t be EQ’d out, and default EQ presets that are weak enough that the review recommends a custom EQ (the setup note points to an Oluv EQ preset) to get its best sound. It is also bigger and heavier than the outgoing Xtreme 4, and the cons call it high priced even before this comparison’s price gap.
What the JBL Xtreme 5 adds: a removable battery, a 7-band app EQ (the Bose has none), Auracast party linking, a 110dB max volume rating, and IP68 sealing versus the Bose’s IP67.
What the Bose SoundLink Max adds: an aux input with 33ms latency, which the Xtreme 5 lacks entirely, and a meaningfully smaller, lighter build for easier one-hand carrying.
Buy the JBL Xtreme 5 if sound quality is the priority. Its measured rank is dramatically higher, and the bass depth and clean high-volume output are the biggest differentiators here.
Buy the Bose SoundLink Max if the $0.95 savings and a smaller, lighter body matter more to you than closing that sound-quality gap.
