Short answer: the W-King T11. It ranks #38 of 76 boombox speakers by sound quality, rated 3.3/5, at $150; the EcoXGear Defender ranks #60, rated 2.5/5, and costs $303.38, so there is little reason to consider the other one.
What the W-King T11 does well: A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
The case for the EcoXGear Defender: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. 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.
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.

The Two Speakers In Full
W-King T11: $113.53 Amazon AliExpress eBay
Pros: A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Its deep bass and 5.1kg size make it a strong option when punch and portability matter more than audiophile refinement. Measured bass extension of 43Hz (-10dB).
Cons: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments. There is no app-based fine EQ, battery life is only a claimed 10 hours, and the external power brick is less convenient than USB-C charging.

EcoXGear Defender: $303.38 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: 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 default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.
