Short answer: the Zealot S95. It ranks #37 of 112 boombox speakers by sound quality, rated 3.7/5, at $157.41; the EcoXGear Defender ranks #84, rated 2.5/5, and costs $299.99, so there is little reason to consider the other one.
The EcoXGear Defender is the longer-running choice. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. It is rated for 25 hours of battery against 12 for the Zealot S95. The catch: 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 Zealot S95 is the better-sounding pick. An affordable stereo boombox with water resistance, a power bank output and linking for up to 100 speakers. It links with other speakers (PartyAdd up to 100 speakers), which the EcoXGear Defender cannot. It plays in stereo from a single unit, unlike the EcoXGear Defender. Watch for: A little rolled off up top and not that balanced through the rest of the range.
Buy the Zealot S95. It is rated higher for sound quality than the EcoXGear Defender and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
