Short answer: the Zealot S67, if you are buying new, though neither ranks well in its class. The Ultimate Ears Megablast ranks higher than it (#87 vs #104 of 105 large speakers, 2.8/5 vs 2.0/5) but is discontinued, so only consider it used; the Zealot S67 is still sold new at $70.94. 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 Megablast is the better-sounding, lighter option. Alexa integration (Wi-Fi + Bluetooth). At 2.4 lbs (1.1 kg) it weighs much less than the Zealot S67 at 5.3 lbs (2.4 kg). The catch: Bass is not very deep compared to the competition.
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.
Buy the Zealot S67 if you want one new; the Ultimate Ears Megablast is discontinued, so only look for it used.

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.
