Short answer: the Bose SoundLink Max if sound quality matters most, the Zealot S79 if price matters most. The Bose SoundLink Max ranks #17 of 126 large speakers, rated 4.3/5, at $399. The Zealot S79 ranks #52, rated 3.6/5, at $106.97, $292.03 cheaper.
The Bose SoundLink Max is the better-sounding, lighter option. A rugged waterproof speaker with deep bass, a very long real world battery and a port that charges your phone. At 4.9 lbs (2.2 kg) it weighs noticeably less than the Zealot S79 at 7.3 lbs (3.3 kg). The tradeoff: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
The Zealot S79 is the longer-running choice. A loud party speaker with plenty of bass, a huge battery that doubles as a power bank, lights and a shoulder strap. It is rated for 50 hours of battery against 20 for the Bose SoundLink Max. The tradeoff: At moderate volume the JBL Xtreme 3 is cleaner and more balanced, and one reviewer preferred the JBL Xtreme 4 in every way.
Buy the Bose SoundLink Max when sound quality outweighs the price for you, and the Zealot S79 when the price outweighs sound quality instead.
