Short answer: the Marshall Middleton. It ranks #34 of 105 large speakers by sound quality, rated 4.0/5, at $215.80. The Zealot S67 ranks #104, rated 2.0/5, at $70.94, $144.86 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Marshall Middleton is the better-sounding, lighter pick. Very deep bass for the size/weight. At 4 lbs (1.8 kg) it weighs noticeably less than the Zealot S67 at 5.3 lbs (2.4 kg). It links with other speakers (Marshall Stack), which the Zealot S67 cannot. Watch for: 5db dip at 1.7kHz and 6.3kHz.
The case for the Zealot S67: It offers a lot of practical hardware for a 5.3 lbs (2.4 kg) budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The tradeoff: Sound quality is the catch.
Buy the Marshall Middleton. It is rated higher for sound quality, and saving $144.86 with the Zealot S67 does not make up for the sound-quality gap.

The Two Speakers In Full
Marshall Middleton: $215.80 Amazon $215.80 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 S67: $70.94 AliExpress $70.94 eBay
Pros: It offers a lot of practical hardware for a 2.4kg budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The large enclosure and dual-driver/passive-radiator layout can provide useful party-level volume.
Cons: Sound quality is the catch. Independent reviewer comparisons report obvious distortion once volume rises past roughly halfway, little true deep bass, and a rolled-off, low-detail treble. There is no app or real EQ to correct that balance, so its long feature list does not make it a good pick for attentive music listening.
