Short answer: the JBL Partybox Encore. It ranks #6 of 75 boombox speakers by sound quality at $230; the EcoXGear Defender ranks #59 and costs $249.99, so there is not much of a tradeoff to weigh.
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 JBL Partybox Encore offers: JBL Partybox Encore uses 135mm woofer + 2x 20mm tweeters. Its 6.3 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 110dB and stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 38Hz specification.
Buy the JBL Partybox Encore. It ranks higher for sound quality than the EcoXGear Defender and costs less, which settles it without a real tradeoff to make.
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.
Battery life favors the EcoXGear Defender: rated for 25 hours against 6 hours for the JBL Partybox Encore.
Water resistance is not close: the EcoXGear Defender is rated at IP67 (brief submersion), well ahead of the JBL Partybox Encore at IPX4 (splashing).
