Short answer: the W-King D10, though neither ranks well in its class. It ranks #79 of 112 boombox speakers by sound quality, rated 2.7/5, at $84.97; the EcoXGear Defender ranks #84, rated 2.5/5, and costs $299.99, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 112 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
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. Watch for: 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 D10 is the longer-running, lighter pick. An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. It is rated for 42 hours of battery against 25 for the EcoXGear Defender. At 7.9 lbs (3.6 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: Upper bass boost, bass not that deep.
Buy the W-King D10. 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.
