Soundcore Motion Boom+ vs Zealot S78

Last updated: October 12, 2026

Short answer: the Soundcore Boom 2 Plus, if you are buying new, though neither ranks well in its class. The Soundcore Motion Boom+ ranks higher than the Zealot S78 (#68 vs #97 of 98 boombox speakers) but is discontinued; its replacement, the Soundcore Boom 2 Plus, is rated 3.6/5 at $179.99 and is still sold new. Both are rated below 3.0/5 among the 98 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.

Soundcore Motion Boom+ vs Zealot S78

The Soundcore Motion Boom+ is the better-sounding, lighter choice. 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. At 5.3 lbs (2.4 kg) it weighs much less than the Zealot S78 at 9.7 lbs (4.4 kg). It links with other speakers (PartyCast up to 100 speakers), which the Zealot S78 cannot. The catch: Default presets are all warm sounding with rolled off treble.

The Zealot S78 is the longer-running choice. A robust 9.7 lbs (4.4 kg) party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. It is rated for 40 hours of battery against 20 for the Soundcore Motion Boom+. The tradeoff: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.

Buy the Soundcore Boom 2 Plus, the replacement for the discontinued Soundcore Motion Boom+; it is rated higher for sound quality than the Zealot S78.

Soundcore Motion Boom+ ranking card

Newer model: the Soundcore Boom 2 Plus, ranked higher, rated 3.6/5, released May 2024. It adds built-in mic and AAC. See every Soundcore Boom generation.

Pros: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Measured bass extension of 52Hz (-10dB).

Cons: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6kHz peak comes out when volume is above about 60%. Not much deeper bass than a Soundcore Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.

Zealot S78 ranking card

Pros: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings.

Cons: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
