Short answer: the W-King D10. It ranks #55 of 75 boombox speakers by sound quality at $84.97; the EcoXGear Defender ranks #59 and costs $249.99, so there is little reason to consider the other one.
What the EcoXGear Defender offers: 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. 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 default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode.
What the W-King D10 offers: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ and bass boost, microphone input for karaoke, MicroSD card support, USB playback, TWS pairing Watch for: Upper bass boost, bass not that deep.
Buy the W-King D10. It ranks higher for sound quality than the EcoXGear Defender and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the EcoXGear Defender. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
There is a real battery-life gap here: the W-King D10 is rated for 42 hours, the EcoXGear Defender only 25 hours.
