Ultimate Ears Epicboom vs Zealot S67: Which Is Better? (2026)

Q: Should I buy the Ultimate Ears Epicboom or the Zealot S67?

Buy the Ultimate Ears Epicboom. It is rated higher for sound quality, and the $157.65 you would save on the Zealot S67 does not close the gap.

Short answer: the Ultimate Ears Epicboom, though neither ranks well in its class. It ranks #83 of 105 large speakers by sound quality, rated 2.9/5, at $228.59. The Zealot S67 ranks #104, rated 2.0/5, at $70.94, $157.65 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 105 large speakers, so if sound quality matters, consider the Tribit Stormbox Lava instead, ranked #3 at $119.99.

The Ultimate Ears Epicboom is the better-sounding option. 17 hour battery with USB-C charging (first UE portable with USB-C). The catch: Not very deep bass for the size.

What the Zealot S67 does well: 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.

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.
