Short answer: the Tronsmart Halo 200, if you are buying new. The Harman Kardon Onyx Studio 8 ranks higher than it (#12 vs #65 of 89 boombox speakers, 4.1/5 vs 2.8/5) but is discontinued, so only consider it used; the Tronsmart Halo 200 is still sold new at $169.99.
Why pick the Harman Kardon Onyx Studio 8: At 3.3 kg, Harman Kardon Onyx Studio 8 combines a 120mm woofer and 2x 20mm tweeters with Bluetooth and aux. The catch: Bass is limited by its 35Hz specification.
The case for the Tronsmart Halo 200: 15,000mAh battery rated 18 hours; charges in 3.5 hours. The tradeoff: Not as deep bass as some of the top ranked.
Buy the Tronsmart Halo 200 if you want one new; the Harman Kardon Onyx Studio 8 is discontinued, so only look for it used.
If water resistance matters to you, the Tronsmart Halo 200 at IPX4 (splashing) holds up far better than the Harman Kardon Onyx Studio 8 at no water resistance.
