Short answer: the W-King X20. It ranks #43 of 112 boombox speakers by sound quality, rated 3.5/5, at $219.98; the EcoXGear Defender ranks #84, rated 2.5/5, and costs $299.99, which makes this an easy call rather than a real tradeoff.
The EcoXGear Defender is the lighter pick. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. At 10 lbs (4.54 kg) it weighs noticeably less than the W-King X20 at 15.9 lbs (7.2 kg). 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 X20 is the better-sounding option. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It plays in stereo from a single unit, unlike the EcoXGear Defender. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the W-King X20. 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.
