These sit in different size classes, so this is not a straight ranking comparison. The Bose SoundLink Max ranks #17 of 120 large speakers by sound quality at $399; the JBL Partybox Encore Essential 2 ranks #6 of 113 boombox speakers by sound quality at $249.95.
The Bose SoundLink Max is the longer-running, lighter option. A rugged waterproof speaker with deep bass, a very long real world battery and a port that charges your phone. It is rated for 20 hours of battery against 15 for the JBL Partybox Encore Essential 2. At 4.9 lbs (2.2 kg) it weighs much less than the JBL Partybox Encore Essential 2 at 13.7 lbs (6.2 kg). It is rated IP67 against IPX4 for the JBL Partybox Encore Essential 2. The catch: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
The JBL Partybox Encore Essential 2 is the deeper-bass choice. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. Its bass reaches about 42Hz before falling 10dB, against 48Hz for the Bose SoundLink Max. It links with other speakers (Auracast), which the Bose SoundLink Max cannot. It has an adjustable EQ, which the Bose SoundLink Max lacks. The catch: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
Buy the Bose SoundLink Max at $399 for a large speaker, or the JBL Partybox Encore Essential 2 at $249.95 for a boombox speaker instead.
