Short answer: the Zealot ZE21 for better sound quality, the Soundcore Boom 2 Plus for the lower price. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The Soundcore Boom 2 Plus ranks #26 at $169.99, $77.42 cheaper.
What the Zealot ZE21 offers: Great value for the bass performance, play time and max volume in the boombox class, though the Zealot ZE41 now beats it out. Watch for: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding
What the Soundcore Boom 2 Plus offers: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
Buy the Zealot ZE21 if sound quality matters more than the price. Buy the Soundcore Boom 2 Plus if the price matters more than sound quality.
There is a real battery-life gap here: the Zealot ZE21 is rated for 40 hours, the Soundcore Boom 2 Plus only 20 hours.
