Short answer: the Zealot ZE01. It ranks #27 of 75 boombox speakers by sound quality at $169.90; the EcoXGear Defender ranks #59 and costs $249.99, so there is not much of a tradeoff to weigh.
What the EcoXGear Defender offers: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode. Watch for: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode.
What the Zealot ZE01 offers: Appears to be the same internals as the S95 Watch for: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers.
Buy the Zealot ZE01. It ranks higher for sound quality than the EcoXGear Defender and costs less, so the other one has nothing left to offer.
The EcoXGear Defender is not a sound-quality pick. It sits near the bottom of the 75 boombox speakers; there are better options higher up.
If battery life is a priority, the Zealot ZE01 is rated for 40 hours versus 25 hours for the EcoXGear Defender.
