Short answer: the Ultimate Ears Everboom. It ranks #35 of 105 large speakers by sound quality, rated 3.9/5, at $159.99. The Zealot S67 ranks #104, rated 2.0/5, at $70.94, $89.05 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Ultimate Ears Everboom is the better-sounding, lighter option. At 2.1 lbs (949 g) it weighs much less than the Zealot S67 at 5.3 lbs (2.4 kg). It links with other speakers (PartyUp up to 50 speakers), which the Zealot S67 cannot. It has an adjustable EQ, which the Zealot S67 lacks. The tradeoff: Careful placement and volume setting remain important for balanced sound.
Why pick 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. It plays in stereo from a single unit, unlike the Ultimate Ears Everboom. The catch: Sound quality is the catch.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality, and the $89.05 saving on the Zealot S67 is not enough to make up the difference.

The Two Speakers In Full
Ultimate Ears Everboom: $159.99 Amazon $159.99 eBay
Pros: Ultimate Ears Everboom uses 2x 56.6mm x 56.2mm fullrange transducers + 2x passive radiators. Its 949 g, claimed 20 hours (Manufacturer specified) battery life, IP67 protection, aux input and mono playback make it a practical option for its intended room or portable use.
Cons: Careful placement and volume setting remain important for balanced sound. Warm tuning with an upper-bass boost and rolled-off treble, and the bass does not go very deep.

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.
