Short answer: the Soundcore Boom 2 Plus if sound quality matters most, the Zealot S78 if price matters most. The Soundcore Boom 2 Plus ranks #26 of 73 boombox speakers at $169.99. The Zealot S78 ranks #73 at $159.68, $10.31 cheaper.
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.
What the Zealot S78 offers: 120W RMS output with 150W peak power, exceptional 40-hour battery life, power bank function, IP67 waterproof, EQ with multiple modes, dual woofers with tweeters and passive radiators, MicroSD and USB playback, AUX input, TWS stereo pairing, USB-C charging Watch for: Gets distorted above 50%. Not much bass. Volume level fluctuates at high volume.
Buy the Soundcore Boom 2 Plus if sound quality is the priority over the price, or the Zealot S78 if the price is the priority over sound quality.
The Zealot S78 is not a sound-quality pick. It sits near the bottom of the 73 boombox speakers; there are better options higher up.
There is a real battery-life gap here: the Zealot S78 is rated for 40 hours, the Soundcore Boom 2 Plus only 20 hours.
