Short answer: the Motion Boom, on both price and ranking. It ranks #14 of 78 large speakers at $109.99; the T9 ranks #38 at $130, $20.01 more.
The T9’s spec sheet reads long: 80W output, a 24-hour battery with power bank function, dual subwoofers, RGB lighting, microSD and AUX support, and even a karaoke mode with a bundled wireless microphone. Our notes still flag peaks in the upper mids that make it sound a bit harsh.
The Motion Boom keeps it simpler and measures better for it. Our notes call it excellent budget-friendly value with a genuinely long battery of its own, 24 hours claimed, and a waterproof buoyant design that doubles as a practical carry handle.
Buy the Motion Boom for the better value and higher ranking. Buy the T9 if the karaoke mode and bundled microphone specifically matter to you.
If water resistance matters to you, the Soundcore Motion Boom at IPX7 (brief submersion) holds up far better than the W-King T9 at no water resistance.
