Short answer: the JBL Xtreme 4. It ranks #44 of 105 large speakers by sound quality, rated 3.8/5, at $309.95. The Zealot S67 ranks #104, rated 2.0/5, at $70.94, $239.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Xtreme 4 is the better-sounding option. A rugged 4.6 lbs (2.1 kg) portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. It links with other speakers (Auracast), which the Zealot S67 cannot. It has an adjustable EQ, which the Zealot S67 lacks. Watch for: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
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. It keeps a wired aux input, which the JBL Xtreme 4 lacks. The catch: Sound quality is the catch.
Buy the JBL Xtreme 4. It is rated higher for sound quality, and saving $239.01 with the Zealot S67 does not make up for the sound-quality gap.

JBL Xtreme 4: $309.95 Amazon $309.95 B&H Photo Video eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5, released Apr 2026. It adds USB audio input, AAC and LC3, but drops the built-in mic. Water resistance goes from IP67 to IP68.
Older models: the JBL Xtreme 3 (ranked higher, rated 4.3/5), the JBL Xtreme 2 (ranked lower, rated 3.4/5) and the JBL Xtreme (ranked lower, rated 3.2/5). See every JBL Xtreme generation.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.

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.
