Short answer: the Gemini GGO-650L, though neither ranks well in its class. Both are rated 2.5/5 for sound quality (#73 and #72 of 89 boombox speakers), and the Gemini GGO-650L costs $99.95 against $299.99 for the EcoXGear Defender, with sound quality a draw, the lower price decides it. Both are rated below 3.0/5 among the 89 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
What the EcoXGear Defender does well: 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.
Why pick the Gemini GGO-650L: At 4.2 kg, Gemini GGO-650L combines 6.5” woofer + tweeter with Bluetooth and aux. Watch for: Bass is limited by its ~56Hz specification.
Buy the Gemini GGO-650L. Both are rated the same for sound quality, and it costs $200.04 less than the EcoXGear Defender.

The Two Speakers In Full
EcoXGear Defender: $299.99 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.
