Short answer: the Zealot ZE21. It ranks #18 of 112 boombox speakers by sound quality, rated 4.0/5, at $187.15; the B&O Beolit 20 ranks #48, rated 3.4/5, and costs $749, so there is little reason to consider the other one.
The Zealot ZE21 is the better-sounding, deeper-bass pick. A rugged battery boombox with unusually deep bass, very long battery life, and stereo pairing for party scale sound. Its bass reaches about 36Hz before falling 10dB, against 45Hz for the B&O Beolit 20. It is rated for 40 hours of battery against 8 for the B&O Beolit 20. It is rated IPX6 against IPX4 for the B&O Beolit 20. Watch for: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy.
The B&O Beolit 20 is the lighter choice. A premium designer portable with 360 degree sound and a top that doubles as a wireless phone charger. At 6 lbs (2.7 kg) it weighs much less than the Zealot ZE21 at 20.4 lbs (9.27 kg).
Buy the Zealot ZE21. It is rated higher for sound quality than the B&O Beolit 20 and costs less, which makes it the one to get unless you need something the other one does better.
