Short answer: the W-King D20. It ranks #41 of 112 boombox speakers by sound quality, rated 3.6/5, at $193; 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 lighter choice. 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 D20 at 14.3 lbs (6.5 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 D20 is the better-sounding choice. A loud stereo party speaker with two wireless microphones, a 24 hour battery 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 D20. 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.
