Short answer: the W-King D10, though neither ranks well in its class. It ranks #80 of 113 boombox speakers by sound quality, rated 2.7/5, at $99.99; the Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95. With prices this close, go by the sound-quality ranking rather than the cost. Both are rated below 3.0/5 among the 113 boombox speakers; for better sound, the Bugani Brief Pro ranks #28 at $99.98.
The W-King D10 is the longer-running option. An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. It is rated for 42 hours of battery against 10 for the Gemini GGO-650L. It has an adjustable EQ, which the Gemini GGO-650L lacks. The tradeoff: Upper bass boost, bass not that deep.
The case for the Gemini GGO-650L: An inexpensive stereo party speaker with a big woofer, water resistance and a 10 hour battery. The tradeoff: Bass is limited by its ~56Hz specification.
Buy the W-King D10. It is rated higher for sound quality, and the $0.04 you would save on the Gemini GGO-650L does not close the gap.
