Short answer: the Soundcore Boom 3i if sound quality matters most, the Tronsmart T8 if price matters most. The Soundcore Boom 3i ranks #31 of 182 medium speakers, rated 4.0/5, at $118.99. The Tronsmart T8 ranks #54, rated 3.6/5, at $49.99, $69 cheaper.
The Soundcore Boom 3i is the better-sounding option. A warm, punchy waterproof speaker that sounds great and is a strong value. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Why pick the Tronsmart T8: An affordable waterproof speaker with upward firing drivers that spread sound around, plus lights, app EQ, an aux input and stereo pairing. It keeps a wired aux input, which the Soundcore Boom 3i lacks. The catch: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass.
Buy the Soundcore Boom 3i when sound quality outweighs the price for you, and the Tronsmart T8 when the price outweighs sound quality instead.
