Short answer: the W-King D20. It ranks #29 of 75 boombox speakers by sound quality at $193; 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 D20 offers: Comes with 2 wireless microphones Watch for: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks
Buy the W-King D20. It ranks higher for sound quality than the EcoXGear Defender and costs less, so there is no real case for the other one.
The EcoXGear Defender is not a sound-quality pick. It sits near the bottom of the 75 boombox speakers; there are better options higher up.
