Short answer: the W-King T11. It ranks #55 of 113 boombox speakers by sound quality, rated 3.3/5, at $116.57; the EcoXGear Defender ranks #85, rated 2.5/5, and costs $299.99, so there is little reason to consider the other one.
The W-King T11 is the better-sounding choice. A weather resistant party speaker with deep bass, high volume and a karaoke mic input. It plays in stereo from a single unit, unlike the EcoXGear Defender. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
The EcoXGear Defender is the longer-running choice. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. It is rated for 25 hours of battery against 10 for the W-King T11. 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.
Buy the W-King T11. 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.
