Soundcore Boom 2 Plus vs Zealot S78

Last updated: October 12, 2026

Short answer: the Soundcore Boom 2 Plus. It ranks #37 of 98 boombox speakers by sound quality, rated 3.6/5, at $179.99. The Zealot S78 ranks #97, rated 2.0/5, at $159.68, $20.31 cheaper, a saving that is not big enough to make up the sound-quality gap.

Soundcore Boom 2 Plus vs Zealot S78

The Soundcore Boom 2 Plus is the better-sounding pick. Quite a bit lighter than most of the other boombox size speakers. It supports AAC Bluetooth, which the Zealot S78 lacks. It links with other speakers (PartyCast 2.0), which the Zealot S78 cannot. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.

The Zealot S78 is the longer-running option. 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 Boom 2 Plus. The catch: 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. It is rated higher for sound quality, and saving $20.31 with the Zealot S78 does not make up for the sound-quality gap.

Soundcore Boom 2 Plus ranking card

Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5). See every Soundcore Boom generation.

Same family: the Soundcore Boom 2 (smaller model, rated 4.5/5).

Pros: 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. Measured bass extension of 39Hz (-10dB).

Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.

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.
