Short answer: the Onn Medium Party Speaker Gen 2. It ranks #65 of 112 boombox speakers by sound quality, rated 3.1/5, at $90; the EcoXGear Defender ranks #84, rated 2.5/5, and costs $299.99, so there is not much of a tradeoff to weigh.
What the EcoXGear Defender does well: A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. It has an adjustable EQ, which the Onn Medium Party Speaker Gen 2 lacks. The tradeoff: 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 Onn Medium Party Speaker Gen 2 is the better-sounding choice. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. It links with other speakers (Party Sync Mode), which the EcoXGear Defender cannot. The tradeoff: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality than the EcoXGear Defender and costs less, which makes it the one to get unless you need something the other one does better.
