Short answer: the EcoXGear Defender for better sound quality, the W-King X10 for the lower price, though neither ranks well in its class. The EcoXGear Defender ranks #84 of 112 boombox speakers, rated 2.5/5, at $299.99. The W-King X10 ranks #93, rated 2.3/5, at $80, $219.99 cheaper. Both are rated below 3.0/5 among the 112 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
The case for the EcoXGear Defender: A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. 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 W-King X10 is the longer-running, lighter option. A cheap, waterproof stereo boombox with a very long battery, loud output and a power bank for charging your phone. It is rated for 42 hours of battery against 25 for the EcoXGear Defender. At 6.5 lbs (2.95 kg) it weighs noticeably less than the EcoXGear Defender at 10 lbs (4.54 kg). It plays in stereo from a single unit, unlike the EcoXGear Defender. The tradeoff: Heavily rolled off treble, less bass than the top ranked.
Buy the EcoXGear Defender if sound quality matters more than the price. Buy the W-King X10 if the price matters more than sound quality.
