Short answer: the Marshall Middleton. It ranks #34 of 103 large speakers by sound quality, rated 4.0/5, at $149.99; the Zealot S127 ranks #45, rated 3.8/5, at $148.85. The price gap is small enough that the sound-quality ranking should decide it.
The Marshall Middleton is the lighter choice. Very deep bass for the size/weight. At 4 lbs (1.8 kg) it weighs much less than the Zealot S127 at 7.8 lbs (3.54 kg). The catch: 5db dip at 1.7kHz and 6.3kHz.
What the Zealot S127 does well: The S127 pairs a claimed 100W amplifier with four drivers - two 92mm woofers plus two 42mm units - in a 33.6 cm cabinet, which points to real outdoor loudness rather than a small desktop box. The tradeoff: At 7.8 lbs (3.54 kg) this is a car-camping speaker, not a backpack one, and it recharges only from a 5V DC input, so refilling a 24000mAh pack takes hours; no charging time or battery-life hours are published.
Buy the Marshall Middleton. It is rated higher for sound quality, and the $1.14 you would save on the Zealot S127 does not close the gap.

The Two Speakers In Full
Marshall Middleton: $149.99 Amazon eBay
Newer model: the Marshall Middleton II, ranked higher, rated 4.1/5, released Jul 2025. It adds app control and adjustable EQ. Battery life goes from 20 to 30 hours. See every Marshall Portable Speakers generation.
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.

Zealot S127: $148.85 Amazon eBay
Pros: The S127 pairs a claimed 100W amplifier with four drivers - two 92mm woofers plus two 42mm units - in a 33.6 cm cabinet, which points to real outdoor loudness rather than a small desktop box. Zealot quotes 20Hz - 20kHz coverage, so it promises usable low bass. The 24000mAh battery doubles as a power bank for phones, while Bluetooth 5.3, roughly 10m range, TWS pairing, USB, microSD and AUX inputs cover most sources. IPX6 splash resistance and RGB lighting suit camping, beaches and evening parties, and reviewers rate it against far pricier JBL models. Jay’s Straight Up Reviews found it a capable performer that is not bass-heavy, and comparisons place it close to pricier JBL models.
Cons: At 3.54 kg this is a car-camping speaker, not a backpack one, and it recharges only from a 5V DC input, so refilling a 24000mAh pack takes hours; no charging time or battery-life hours are published. IPX6 survives splashes but not immersion, and Zealot lists no maximum SPL, sensitivity or impedance, so real output capability is unknown. There is no documented companion app or custom EQ, leaving tuning to on-board presets. No independent lab has measured its frequency response, distortion or loudness, so the 20Hz claim stays unverified.
